Just changed the 5wdumbass oil in my 2011 Range Rover Sport for 5w40 C3 and the first thing I noticed is the engine is noticeably quieter! Makes sense, but didn't really expect it, so a nice little bonus. 121k miles (200k km) on the clock now, so hopefully this change will keep it running smooth for many more years. Thank you guys, und vielen dank! 🙂

Land Rover are the leading experts in making changes that cost more and are worse from a structural or reliability standpoint compared to their previous variants. I can confirm this as a long time owner from RRC, Series and original Defender.

Hi, I’m an ex D3 and D4 owner, fantastic cars. I am now a Toyota owner after over 30 years of owning Land Rovers. Your Toyota comments are so funny, it’s true, they just work without any issues. I went to Toyota because I just didn’t have the time to keep up with the constant repairs and high maintenance with the Land Rovers. I really miss the Discovery 4 though, but now I have a life and money in the bank! Great content, although I’ve gone over to the dark side I’ll still be sticking around with you guys, great and unique channel, you make a great team.

Replace oil pump now to make sure that is the reason for low oil pressure before you pull the engine 😊

[@elrodjenkins]

The chances the low oil pressure is due to the oil pump is low. At the end of the day, the oil pump creates flow. Pressure is achieved with the bearings.

Arh. I think you already have the answer Christian. Swop out the pump now so you can rule it out or in as the fault. Very entertaining video again. Love your German logic.

You can change the oil ‘weight’ dependent on climate and session… a oil suitable for Finland is going to be different to Africa, the operating temperature ranges are vastly different. People get to hung up on ‘what the manual says’, it’s a guide. The additive package and quality of the oil is what peopled should focus on.

[@egSmith-sp9gl]

oil weight is directly proportional to its mass !

[@sheilamorrison1954]

The operating temp will be very close. The engines have a cooling system with a thermostat for a reason......

[@jamest5149]

@@sheilamorrison1954​​⁠you would think they would closely match but they don’t, data logging shows oil temperatures lag behaving water temps a lot, partly due to localised heating of the coolant in the heads around the exhaust ports plus the coolant temp sensor normally being located in the coolant path between the head and radiator. Oil temps take so much more time and miles to get to operating temperatures than anyone expects especially on cold days where oil might not actually get to temp for most journeys. This delta can be as large as 20-30 minutes or more!

Engine wear is in the equation also. Wider tolerances in a worn engine will need a ticker oil than when the engine was new⚠️

[@dustcommander100]

My eyes have been opened with regard to oil types. My wife's 2007 Camry was the subject of oil use issues that some thought should result in a recall and engine repair or replacement. You may not know, but Toyota would test the oil consumption by filling to the proper level and then "sealing" the system. They would recheck the level after the owner drove the car 1000 miles and brought it back to the dealer again. Toyota would not repair an engine unless it used over 1 quart of oil in 1000 miles. During the effective time of the tests (age and mileage), her car did not consume oil. Later on, it began using a great deal of oil - possibly half the capacity - between oil changes. For some reason, I felt I could not use oil other than the type (5W20) marked on the oil filler cap. A friend suggested I try another weight oil to see if it helped with the consumption. I switched to 10W40 oil, and the oil consumption practically stopped. This seems to have allowed us to use the car for another 50,000 or more miles so far - beyond what seemed to be where it was worn out, based on oil consumption. In some cases, the dealer is not going to help with a problem, and you have nothing to lose by trying something the dealer does not recommend.

[@leop3009]

Oil Cap viscosity markings are to satisfy the EPA. It is not, usually for the health of the engine. And yes, 5/20 whether in a mazda, toyota, honda or Ford, GM, Chrysler.... They do burn quick. So the 30s and 40s are better when at operating temps. If you do live in the colder parts of the US, i would suggest a 5/40 vs a 10/40 for better cold starts....but remains the same when hot. (in Alaska, u may require to go 0/40 vsa 5/40)

[@sweetpepsi100]

Hi Christian, I bought my 2016 Disco 4 in July this year and about 2 wks ago, I got Service Required indication came up. I saw your video. You changed to 5w40 oli on Disco 3, and I, too, was going to change to 5w40. But my 3.0 SDV6 has start/stop, dpf filter and Adblue, I kind of chickened out fearing it may cause engine problems and used 5w30 oil(landrover Jaguar specification) and You were right in saying that 5w30 oil is just like pouring water, it's so thin and it worried me, if this watery oil would be sufficient enough to keep engine parts well lubricated. Then I added ZX1 Lube Oil, which is protection/friction free lubricant for essential engine parts. After doing the service, my God what a difference that ZX1 Lube oli made. The engine runs very quiet and silky smooth and on top of it the best thing happened is that I used to get with normal driving 26 mpg and now I'm get nearly 28.7 mpg. I'm delighted. But I think I'll switch to 5w40 on my next service.

You can reuse your copper washer again, it work hardens. But It's just a matter of glowing it with a blowtorch to make the copper soft again. And C4 oil is only available as 5W-30.

[@garymcmullin2292]

you two are a couple or wonderful characters, love the entertainment value of the video but also appreciate that you pass along much technical information. If it were my decision I would opt to replace the oil pump ASAP because it is essential to the engine. Could be when you do the replace you will find some other problem that was causing loss of pressure or lack of oil feed to the pump? Whatever the case I see it as a problem that needs solving sooner than later because you are risking accelerated wear....even in just the summer months interval.

[@philadams92]

Another great video, I have watched for 18 months now and enjoyed every one. I couldn't believe I did not think to put 5w-40 in my own Disco 3 but within a week of you doing Vera's I did mine, I have changed the oil pump (and belts) twice on my 176000 mile (not Euro KM,s) and the engine runs very quiet and smooth in fact previously I had a Discovery Sport with the same engine with only 60000 mile on it and that engine was defiantly louder than my Disco. Anyway we all know just regular engine oil changes will prolong the life of any engine I usually go no longer than 3-6 thousand miles between oil changes. I changed the oil after your oil change but also I added Wynns additive which has the consistency of honey (as used by Derick on Vice Grip Garage) which I have used over the years. So heading towards a quarter million miles (hopefully) unless you would like to do an engine refirb for me Christian lol that was a great series of videos. Keep up the fantastic content all the best Phil and Louise

[@theondebray]

Good point about the oil. Since new, I have used 5W-30 oils, but recently as the engine is ever-so-slightly tired, I put in a hefty squirt of gear oil! That quietened it down nicely, and SEEMS to have improved compression & starting. So 5W40 is the way to go. (Also, I have been using an anti friction additive Activ-8 in my engines for years, greatly reduces wear in the long run.) Good vid, thanks.

Hi what weight of gear oil did you use & roughly how much of a squirt,300ml,500ml ?

Thank you so much for this step-by-step instruction for an oil change. I just made the first oil change on my new old LR4 and it worked out perfectly. Btw I used a pizza cardboard from a supermarket pizza which I placed over this frame as a shield which made the oil run smoothly into the bucket. Not a single drop spilled 🙂

[@DragicaKajganić-n7g]

2.7 and 3.0 hdi engine was originally designed for 5W-40 and then due to marketing and idea of less internal friction and lower fuel consumption changed to 5W-30. Than suddenly in Norway we had maby engine failures related to oil because it showed that 5W-30 brake apart by oil shreading and high tempts just over 5000 km. I would reccomend 5W-40 quarc 9000 total ineo. Magnatec oil you showed is branded as synthetic but its actually semi synthetic with esters.

[@360plussynthetics]

This was the most fun video of oil change and maintenance I've seen in a while. Love the banter and comments between you two and the maintenance being performed. 👍🏻

[@SiCrewe]

Vera, tell Christian that the only way you're going to let him wait until winter to replace the oil pump is if he buys a replacement engine that can be fitted immediately in the event of a catastrophic failure. I suspect the reason Christian isn't in a rush to fix it is because he thinks there's some other problem and a new oil pump won't help. If that IS correct, and the engine requires a major rebuild, the cost of buying a new oil pump is going to be insignificant compared to the cost of rebuilding the engine so it won't really matter if you try a new oil pump before starting more major work.

[@nihallee]

I wouldn’t change that oil pump yet but keep monitoring it closely. Also, make sure to keep us posted on that JLR business meeting!

[@graemevass745]

[@aztech4x4mechanical]

Just to clarify a few points: D4 engine bash plate uses the same bolts as a D3, somebody has changed them to torque. Not all world regions have a DPF fitted to the D4 (no DPF on the D4 in Australia) I actually don't agree with blowing out air filter, simply replace it. I recommend to all my customers to do a service every 10K changing engine oil, oil filter, air filter and fuel filter. At the end of the day the best thing you can do to an engine is change the oil on a regular basis. While I am certainly not a Land Rover fan boy remember that the V6 2.7 and 3.0 is a rubbish Ford engine. I'm a small workshop and I have probably done at least 30 engine replacements on both the D3 and D4. Saying that I can show many D4 models that have over 300K and running well. As always keep up the fun videos.

[@DiscoGruffalo]

My 2012 D4 sump bash plate has 13mm head bolts the same as the D3. I suspect the previous owner / LR garage gorilla rounded off the 13mm heads and replaced them with whatever they had to hand. Your torx head bolts actually look like seat bracket bolts. I also use a Femco quick drain on the drain hole, and I also use the suction tube. Well done for finding the reason for the differences in the oil filter, I have often wondered, but never investigated. I have used 5w40 in my D3 in the past when it was working a lot in the south of France. I currently use 5w30 C2 PAS spec in my D4 but am considering changing to 5w40 C3 The D4 has vacuum supplied engine mounts, and if you see the actuator arms on EGR cooler valve are rattling, the vacuum pipe to the engine mounts is compromised. (My engine builder, Marko at QP Online) told me this. I have used Ravenol STF 0870 for years, but now Ravenol tell me that The new RAVENOL Transfer Fluid DTF-1 replaces the RAVENOL Transfer Fluid TF-0870! I use a 5 litre garden pressure sprayer to fill my diffs, much easier than all that pumping. And I have found that fill to spill on the diffs and transfer box takes just under the measured amount of oil, so fill to spill it is. My cost per km on my 320,000km D4 for the last 215,000km is €0.21/km including a full engine rebuild due to a snapped crankshaft at 198,000km.

[@Okierover]

Your graphic is perfect. Love that. I have a 1993 Range Rover Classic petrol. I upgraded my oil to 20w50. Manual calls for 10w40. But using the right oil for the right climate matters. Love the videos. You two crack me up.

[@julesviolin]

Also it depends how worn the engine is. Unipart used to suggest thinner oils for newer engines and thicker for older ⚠️

[@shaunbava1801]

In the US the ford f150 diesel has the same engine basically and almost everyone including ford dealers uses 5w40 HDEO oil, ford sells the magic 5w30 oil under their own label but from what I gather they advise for severe duty to use 5w40 ACEA E9 oil.

[@zech007]

5w-40 on all diesel no exception is what I use on all diesel, help with fuel/oil dilution, oil sheering, oil pressure and oil consumption.

[@lewlewis6511]

I do the same, always have done and always buy Diesel specific engine oil. I have run Toyota 4x4's for decades, in the handbook the range of approved oils is huge depending on typical local ambient temperature, am yet to have any issues with any of them save a failed alternator once.

[@defendermodsandtravels]

Tip. I hate removing oil drain plugs because (a) they a habit of dropping into the used oil, and (b) I often get a squirt of oil down the sleeve of my overall. I installed an oil drain valve some years ago and it's great - really quick and no mess.

[@stephan707]

Prefilling of oil filters mean to introduce a cup of unfiltered oil into the engine when starting. Caterpillar does not allow this procedure to avoid any oil contamination during oil change. Of course in the quiet atmosphere of a home garage it seems different but better safe than sorry.

My understanding is that different oil viscosity can be used depending on ambient temperature. Probably not the case so much with modern oils, but likely why landrover may have specified 5w40 in South Africa and 30 in germany.

[@m3baller675]

Hello Christian and Vera! Thank you for leading me to this video. I am also experienced in automotive, but this is my first Diesel engine. I have done a lot of research on the DPF oils and can add a couple of things I've read from the manufacturers - with C1 and C4, they don't make it in a 5w40, only 5w30. I also don't want to criticize, but just bounce some ideas off of each other, that C3 is actually considered a mid-SAPS oil, not low-SAPS like C1 and C4 (C4 has the higher HTHS rating). I don't know if this was a mistake or not, but with LR calling for a low-SAPS engine oil, do you all have any concern over using a mid-SAPS oil in regard to the DPF clogging over time?

[@m3baller675]

@@TobiasCat-nb9lg This sounds like you are talking about gasoline spec though, which of course any oil could be interchangeable. I understand some oils will better protect the engine, but my concern about this post is clogging the DPF with mid-SAPS when the spec calls for low SAPS.

[@paulandbeauoutdoors2685]

I changed to Ford Motorcraft synthetic 10w30. The same oil that goes in the 6.7 power stroke. Been testing it at black stone labs in Indiana. It is at least twice as good at metal protection than the Castrol from Land Rover dealer. And it’s cheap.

[@umbrela_Corp]

Hey guys, randomly ended up here from vw touareg videos, 5w 30 only good for early stage of vehicle life i personally have always ran petrol boxer engines or turbo diesel cars 10-40w regardless of the deal oil company made with an car company. Few things to consider offcourse is if a vehicle fitted with a dpf, you may have to avoid small trips thats all!

[@balkanca]

Once again, I firmly believe you made a good decision. What would really make this more interesting is, if you haven't disposed of the old 5W-30, you could get a small sample (100 ml or so) for a used oil analysis and do the same with the 5W-40 after 2 oil changes with the same oil for consistency purposes. One suggestion I would make though is to replace air filters as opposed to blowing them out with compressed air. Part of this is because the filter media is not designed for the type of air pressure you would see out of an air compressor. The other being, you cannot clean the filter out completely and end up loosening dirt that could make it's way into the intake when the filter is put back in service. This could also show up as elevated silicone levels in a used oil analysis. With that being said, considering the South African A3/B4 recommendation, which is essentially a full SAPS oil, you could take that up a notch and use a heavy duty engine oil that's has an ACEA E7 rating with a much more robust additive package than any other regular oil. Something like Mobil Delvac 1 5W-40 comes to mind. As for the differential, 75W-140 is a great choice. Yes, fuel economy may take a slight hit, but in the grand scheme of things, offers better protection for your gears. I notice you also used vollsynthetisch labelled oil, which in Germany means it's POA based, making it an even better choice!

[@richardweerasinghe3296]

That’s some good info!

[@Vera_and_Christian]

Thanks for the feedback. I thought about a oil analysis but I would not be able to interpret the data. The air filter was only 8 month old and this is why I put it back in. I only checked if there was dust using a air gun. It was not my intention to clean the filter. Talk to you see Cagri, Christian

CASTROL MAGNATEC 5W-40 DPF C3 has 13,9 mm2/s at 100ºC, which is close to +40% more. At 40ºC the viscosity is 89 mm2/s, which is +65 % compared to C1. It looks like a big step up and sulphur content is +40% compared to C1. Would you consider using Ravennol HDS 5W-30 C4 in the 3.0 liter D4 ?

Hello Christian . If your worry is the HTHS , there are 5w-30 C3 oils . Going from C2 to C3 there is a significant difference and makes sense. Going from 5w-30 to 5w-40 ... for sure will not hurt but not benefit much either... Engine oils - never run out of arguments 🙂 L.E. Since it would be crazy to have a D4 as the only vehicle in the family I also own a small Toyota hybrid bought from new. Despite the fact that the owner manual and all official documentation states 0w-20 oil should be used, at the annual inspection, dealers from Belgium, Germany and Luxembourg all put in 5w-30. And I don't think it is because of the hot climate :) . I even asked why they do this, the answer was invariable - for better protection, that the 0w-20 trades protection for fuel efficiency and they don't even bother to have it on stock.

Your videos are the highlight of my KZbin week! Thank you! I had a thought ( which doesn't happen very often, and when it does, is normally not very impressive) but, isn't your aftermarket oil pressure guage causing your pressure problem?

[@Vera_and_Christian]

Hello Sean, I also tried a direct mounted oil gauge. Not the best one either but it does read higher on my LR4... Yes, the chineese electrical gauge sucks. Christian

[@simondrive4616]

These videos make my week 👍and as an English man who owns a defender I can say this video sums up completely why the U.K gave the world Land-rover and Germany gave us Mercedes Benz😂😂

To save the cost of buying a new oil sump plug for every oil change (which is recommended), you could instead buy the _rubber gasket_ for the sump plug. For the _Discovery 3_ , I use the _Dorman 097-139 Rubber Drain Plug Gasket, Fits M14_ . When changing the engine air filter on my Discovery 3, I also usually clean the _Mass Air Flow (MAF)_ sensor and _Manifold Absolute Pressure (MAP)_ sensor with an electrical sensor cleaner. It's supposed to improve fuel efficiency and performance.

[@Vera_and_Christian]

We do that also. 👍😃🙋‍♀️Vera

[@Vera_and_Christian]

I cleaned the sensor 2 or 3 videos back. I also bought seal rings but they do not fit as well. I must have gotten a bad brand. Thanks. Christian

A trick for transmission oil - put the bottle with oil to the hot water to warm it up before filling up the transmission or differential

[@Vera_and_Christian]

Now you tell me after I broke a sweat Lol. Good idea. Christian

[@bobby3378]

Watching back some of your older videos. Very useful knowledge presented in a light hearted way which makes it easy to watch. Glad to see the support for your channel continue to grow ( I can tell by the length of the Patreon roll) Keep up the good work.... we Discovery owners need the backup.😁😁👨‍🔧👩‍🔧

[@Vera_and_Christian]

Yes, without our wonderful Patrons we not be doing KZbin videos anymore. 👍🙋‍♀️

[@jeffreywilkinson2679]

Heh Christian, I presume JLR are meeting with you to discuss establishing that "Centre of Excellence for Quality and Reliability" in your garage. Yes? It will be a fascinating meeting I am sure. Well done. Best wishes to Vera. I enjoy your work so much.

[@aaronboucher629]

Landrover has a long history of speccing oil that barely works for its products.. You know like atf in manual gearboxes etc.. ....love your video guys....

[@lukekirkby5304]

You do good work and explain your work very well. I must admit I cringe everytime I see those certain green bottles. Had to recondition many engines for a particular manufacturer that exclusively use this oil. They may have improved their formula but after many engine failures due this particular oil I recommended going to a oil brand we used on all engines. Problem solved never seen those again for those problems. Hello from 🇦🇺

[@tonyallam8371]

In my LR 3 V8 4.4 I use Castrol 5w30 however i then add STP oil treatment and it makes a huge difference to the engine sound (much smoother). Not sure what others think of STP versus Liqui Molly.

[@Vera_and_Christian]

It‘s a V8 so no need to not go by the LR spec, like we do on the V6. We, however, do not use additives. 👍👌🙋‍♀️

[@markwhitton8785]

Just checked my D3 (2008) servicing records, have been using C3 5W/40 (mag prof) since at least 2013.

[@paulreeves5012]

Hi Christian and Vera. Thanks another great video and the slump in Christians shoulders when Vera ordered her oil pump change was funny to see. Everything you go through is of interest as I do as much of my own maintenance as I can and the Discovery is relatively easy to work on (I have a Saab 9-5 and that thing is frustrating to do anything to!) but I'm not blessed with a garage and a pit as you are but some home built ramps help out. To give the Toyota drivers an idea as to what is coming up, can I suggest that you use a grading system for the jobs you take on? So something simple like a oil change would be a 1, Oh My God on the Vera scale, while a major operation could go up as high as a 10, Oh My God on the Vera scale.

[@keithknight1107]

I love watching you too you make a good pairing if I was you I would replace the oil pump and if it's possible check the main bearings on the crankshaft keep doing your thing I love watching you on Sunday morning

[@Vera_and_Christian]

That is the plan, when we change the oil pump, to remove the sump and check the bearings. 💪👍🙋‍♀️Vera

[@guidogrommeck3247]

Danke für das Video. Gute und wichtige Informationen, die zum Werterhalt des Disco beitragen.

[@michaelblaich3685]

Hi Vera and Christian, After a filter change my oil pressure comes in around 2 seconds. You can hear it with the valve tappets easily. But the crankshaft will do some turns without sufficient pressure. In consequence I dont change the filter on each oil change because I am changing it not later than 10000km. What i would really be interested in is how the drain plug or check valve of the filter housing is working on the D4 3.0 TDV6. Its because I saw one picture in the net where this valve was not tight due to debris so that the filter housing was drained every time you are stopping the engine. I didnt understand exactly how it works and how it is constructed but I am afraid that it may be a major risk for the engine if this valve is not really tight and drains the filter housing frequently. With the 5W30 you are absolutely right. The engine is extremely short because initially it was planned for an east west fit in the engine bay of a french sedan car. The widths of the bearings and the (Stege) of the head gaskets are paying the price for this. Good video, as always. Thanks for this Best Regards Michael

[@Vera_and_Christian]

The drain valve on a D4 may not close properly if the oil filter is a bit short. The filter would not push the drain closed. This would be catastrophic as the oil pressure would not build up fully and what you said too. Our d3 takes 5 seconds to build pressure at the moment. It used to take only 2-3 sec. Christian

[@michaelblaich3685]

@@Vera_and_Christian Thanks Christian. Yes, thats true. Thats the reason I dont buy cheep maintenance stuff. But its good to check after an oil change the time it takes to get on pressure. Then you can be sure that the drain plug is closed. But what is when the check valve is not closed due to debris? I think the oil pressure would not be affected but the time it takes to build up pressure is long when the engine has been standing still for longer time. Maybe its worth to check the tightness of this valve everytime you are changing the filter. You only have to close the drain hole in the filter housing and fill some oil in. And then wait if it gets drained or not. If yes, one should take out the filter/cooler housing and maintain it. Cheers Michael

[@jamest5149]

I would change now, you know first hand how much work and money it takes when the engine goes boom 🤯👍

[@ragfour9303]

You are asking a pump designed for 5W30 to push a thicker oil.. your oil pressure may well drop. In SA, with higher ambient temps, the 5w40 would have a similar consistency. Consider a quick test back to 5W30 using a cheap oil. Save the 5W40 (if you wish to re-use it) just in case :)

[@khalilrazak6486]

​@teevee2145 It's viscosity is higher therefore it is thicker.

[@danielderiecroft4948]

You do better than i, after working on all my cars the Land Rover makes me want to bang my head on the work bench some times. Still loving you videos

[@Vera_and_Christian]

😅👍🙋‍♀️Vera

[@jasoneyes01]

5w40 gives you more wear protection at the expense of fuel economy theoretically. It protects the engine from fuel dilution which happens as the engine blow by increases with age. You can get oil starvation at extreme freezing in cold engine. Some oil pumps and vvt systems are too fragile to run high viscosity oil in newer cars. You can end up destroying a pump, stretching timing chain, or variator.

[@Vera_and_Christian]

We only talk about the Lion TDV6, 2.7L and SDV6 3.0L. Not any other engines.👍🙋‍♀️

[@hammyh1165]

Another excellent video 🙂. Change the oil pump now , just to be sure.

[@gettin-sendy]

Why did the front diff and transfer case get neglected? Did the trans and rear diff. I will tie in a fuel filter change every 50k km with the trans, transfer and diff oils. 👍

[@gregculverwell]

You are olon a contentious subject! There are endless arguments here on YT on this subject. I also have opinions. Firstly one needs to bear with that the manufacturer does not care about longevity (quite the opposite) but they do care about emission certification and warranty claims. So they will specify a grade of oil that ticks both boxes - lowest possible drag, consistent with low claims due lubrication failure. Also the additve packages have changed. Zinc is excellent anti wear agent but it poisons catalytic converters, so it was replaced with poor substitutes. Beyond that it is up to the owner to choose the right oil for the conditions they are driving in. I'm in South Africa where we have extremes. I have seen - 12c before dawn and +34 by midday in winter and in summer +52c at the same location. The handbook for my old Landcruiser may say 10w-30 but I use 5w-40 and am extremely gentle until up to temperature on cold mornings.

[@Vera_and_Christian]

Thanks for the info and feedback out of South Africa. We also got extreme conditions here. Check our next video at the end scenes. I revel the big secret why I drive a Discovery 4 and not a What Cruiser. Christian

[@maxchobotov9501]

Hi guys! Thank you for your love to Disco that you are sharing with us! Absolutely love watching your channel 🤗 I know that you runs diesel engines on your both Discos, but maybe you can still express and share your own opinion about which engine oil would you prefer to use if you’ve had a gasoline V8 5.0 engine? I own 2012 Discovery 4 with gasoline V8 5.0 liters engine (engineered by Ford as far as I know, maybe I’m wrong) and it has 93000 kilometers on clock, on the oil cap it says to use Castrol 5W20 which later was switched to 0W20. As per my request to LR international support the recommendation is to use engine oils with following requirements SAE 5W20 WSS-M2C925-A or SAE 0W20 STJLR.51.5122.

[@lindsayrixon7402]

😂😂Cracking up, what a hoot of a channel. I’m now a subscriber and it will be my Sunday night viewing complete with beer and chips. Great work, from Oz 🇦🇺

[@gepwxaqdfsidsesg1548]

OEM oil pumps are cheaper from a Peugeot / Citroën dealer. That's what I fitted to my Jaguar XJ 2.7.

[@simon-mouse8739]

Definitely replace the oil pump now. Don't risk running low oil pressure for any longer 👍happy wife, happy life and in this case a happy Tdv6 😎

[@Raysthebars]

This guy & his wife are fun and highly informative. Euro-Pros for sure 👍🏻👍🏻 🚙💨💨

[@justinsmith6296]

Another great video 👍 Christian you could make changing an Air filter video worth watching 😆 as for the oil pressure issue, I would definitely look at changing the oil pump now to help with future diagnosis of the pressure problem.

[@Adventures-with-Ty]

I remember you saying that premature was not a good word for us guys ! I say leave it in, enjoy your vacation then do it as part of the engine overhaul. Another great video. I’ve ordered the magnatec 5w-40 DPF version for my next oil change. I’m trusting you guys more than my own mechanic !!

[@Vera_and_Christian]

😅👍 🙋‍♀️Vera

[@Vera_and_Christian]

I ordered a pump and I intend to change it this week. The big benefit is, that we all will learn if a cheap pump can really be the reason for low idle pressure and slow build up. Video will be out in 2-3 weeks because we got to fix the rear brakes first. Christian

[@maximshilov]

Hello from Kazakhstan. I think that for the engine to be better protected, additional parameters need to be considered. Certainly, oil viscosity is crucial. I believe that for greater protection, a more viscous oil like w50 with a stronger base and fewer polymers added to increase viscosity would be suitable. The difference in fluidity between w40 and w50 oils is not significant, but the HTHS value and viscosity(100 to 150 degrees) favor w50. This is because the oil can heat up beyond 110-120 degrees, and during this process, the viscosity can drop significantly. If you measure oil pressure at 110-120 degrees, the pressure can be below 1 bars, even in a new engine. In reality, this is very low, especially if you are driving on mountain serpentine roads or moving on autobahns at high speeds. Therefore, more viscous oil will help increase pressure. Next, the original oil pressure sensor should be replaced with one that gives a warning if the pressure drops below 1 bar. And most importantly, the coolant and oil temperatures should be lowered. I believe the ideal parameter is 80-90 degrees for the oil all time. Structurally, the oil cooler is not in the most optimal place. This can be improved by modifying the oil cooling system, moving the cooler from its standard location to a separate radiator that cools the oil with the airflow during movement. The oil filter can also be placed separately. These solutions exist and are used in racing tuning. Replacing the thermostat with a colder variant that opens at 82 degrees can further enhance cooling efficiency and protect the engine under varying operational conditions. Additionally, it is very important to change the oil every 5,000-6,000 kilometers. Thank you!

I can't find a c3/c4 oil where I am at in Canada - only a3/a4 UGH. Going to get going on all this soon! Thanks for another great video!

[@timwyld573]

Another top video. I am going to change to 5w40 on the next service. I do a fair amount of short runs for work and the school run here in the UK. QUESTION? For a while now I have had a small amount of oil pooling ontop of the oil cooler on my D4. We know its not leaking oil but the tech said it is likely to be vapour from around all the hoses in and around the throttle body. Could the 5w30 be getting so thin it escapes past seals? The cooler is good and the plastic filter housing is not cracked. MY2010.
