Engine oil COMPARED at 5,000km vs 10,000km vs 20,000km! This'll make you service your 4WD RIGHT NOW!

Manufacturer engine oil changes... MYTH BUSTED? Shauno answers the age old question of whether or not changing your oil more often REALLY makes a difference!
Factory service manuals often recommend oil change intervals around 10,000kms, but Shauno explains why that might be WAY too long for your 4WD!
Watch & see what actually happens to the oil inside your engine if you leave it too long between oil changes, especially if you drive your car short distances without warming it up, tow or drive it hard!

10,000kms or every 6 months is fine with a new filter & a decent oil everytime for me. I've never had a problem nor any diesel 4wd we have had in the family. Only time I change it before 10k is if it's been longer then 6 months since servicing it and Just do it for peace of mind or doing a trip away so it's 100% before leaving and if your smart, you would be under the bonnet anyway prepping it for the trip so why not spend a hundred dollars on oil & a filter while your under there. Doing it every 5k isn't bad if you tow a tool trailer/caravan everyday as it's added load on the motor so working twice as much as you would driving around town each week like most people do with families etc.. Saying all that, each time you should check the oil level, colour, metal in the bottom/filter etc and go from there with how you decide to service your vehicle. Mines never been bad enough to worry me when dropping it so 10k is good enough for me and how I drive and use it. Every motor is diffrent, how the 4wd is used, weather conditions and so on.. so don't base your vehicle health on someone else's 4wd expecting it to go the same distance and perform the same.

@@jamezxh it’s all fun and games to laugh at something, but actually if you run the heater flat out that in turn can cool the cooling water which will help cool the cylinder heads a bit, on a car with a marginal cooling system that could be the difference with it pulling some ignition timing or not, could be the difference of a couple HP. Also in the ecu program of my ba falcon there is provisions to modify ignition timing with the heater position, usually used to retard timing to increase engine temp to heat the heater up quicker, it’s all set to zero but if I were to put -2 in those cells and throw a couple points more octane in the tank turning the heater on full would gain 2 degrees timing advance and with the higher octane to stave off spark knock that could gain me 6 or 8 HP. Also an engine that pulls enough air will gain a few HP from a less restrictive air filter setup. A k&n pod filter in a proper enclosure to feed it cold air is worth almost 20 HP over the stock filter arrangement at peak rpm (6500) in my heavily modified V8 falcon. It’s all well and good to have a laugh at young blokes that try all this on a stock v6 commodore for no gain but in the right circumstances it certainly can make a difference.

My oil gets changed every 6 months at approximately 6-8000km depending on my driving (less in the winter but more idle time as Canadian winters are rough).

We at Low Range 4x4 Adventures service our Colorado at the recommended 15000km interval, when doing lots of towing we do more regular oil and filter changes at least 1 extra between services. We also do a full front and rear diff oil change to protect our lockers and something a lot of people may not know is that lockers require a different oil than the regular diff. Finally we also check gearbox and transfer case oils every service, if they are at all contaminated they are changed as well. We also regularly check brake/clutch fluid and change more regularly then recommended as we do a lot of towing so it needs checking more often. Recommended diff oil for an RG Colorado is 75w-90 however for lockers ARB recommend 85w-140 so this is what is used and changed every 15000km.

I’m in the U.S. For all my vehicles, I use only Amsoil Signature Series. The oil has very little burn-off which helps greatly with reduced deposits and with extending the life of the emissions and cat systems. I change out between 10,000 - 15,000 miles (16,093 - 24,140 kilometers) and burn thru about 1 1/2 quarts per oil change. The oil is rated to go up to 25,000 miles (40,233 kilometers) with the proper filter. This all depends greatly on how you use your vehicle. All my vehicles have lasted me close to 250,000 miles (402,336 kilometers) before I sold them in still good condition. I would encourage everyone to use only top quality synthetic oils, even though they cost more, as they will greatly extend the life of your engine and transmission. The oil analysis all report back as having many thousands of miles of life left in the oil, even at those higher mileage uses.

Hi Shaun the reason why Diesel engine oil goes black is because it is a high detergent oil designed to de carbon the engine to prevent Diesel engines from getting pre ignition.

Hi from France ! Thanks for the insights on oil contamination, and especially for petrol engines, I didn't know that oil can get contaminated by water if not running at operating temp ! On my Jeep Grand Cherokee WJ, I usually change engine oil every 4000 to 5000km, because I wheel it pretty hard, I abuse it quite a lot (man this 4.7 V8 sounds so gooood), and also because it is as per manufacturer specifications ! They actually propose two plans for vehicule maintenance, wether you use it like it was designed for, or only on pavement ! That's pretty neat if you ask me ! I obviously change oil filter when I change oil, I don't understand people changing oil but not the filter, resulting in immediate contamination of your engine oil. Regarding transmission and transfer case oil and filter, I change those every 20000 to 25000 km, or earlier if I see darkening in the oil (I'm checking all my oils every two fuel tank refills, people are looking at me like a madman at service stations). And since I have factory limited slip differentials, I check on them regularly to see if the oil does not smell like burnt (happened once, I might have had too much good times in the snow), and if no water has entered differential housing when crossing deep rivers. Since I have to use the expensive Mopar additive especially made for those limited slip diffs and it is hard to find in Europe, I change diff oil only every 30000km. Have a great day, thanks for all the amazing content ! I learned how to use winches the right way by watching you guys, and I can't thank you enough for that

[@eaglen00b]

It all comes down to HOW you use your vehicle. I've got a 1995 1HZ 75 Series Troopy from new. Followed the servicing/warranty booklet diligently with 5k servicing intervals until I reached 250,000kms thereabouts. From there it was a 10k oil change interval with new oil filter. Fuel filters are changed every 30k or after a long trip needing a refuel at a bowser in woop woop. Granted, the oil level on the dipstick does drop from the FULL mark to around half by the time the oil change and service is due. 547,000km later, still going strong. Doesn't blow smoke, fires up on first crank, idles and revs smoothly, fuel consumption is still about the same. Original engine from factory too. Oils and filters have come a long way since the days when my rig was built, so it's okay to extend the oil change interval on a 1990s 1HZ Troopy.

Who knows but a general good time to change is still around that mark, not saying you cant do it earlier but your just over maintaining increasing oil waste, if your driving like a mad man or going off road every weekend off course service intervals are going to be closer as it comes under adverse conditions, i would say in the case of shauno, thats more that defiantly adverse conditions, for someone like me who doesnt get out too much or put heavy loads on my vehicle, sticking to the service intervals is a great way to keep a car healthy, sorry if im abit lacking in knowledge, i’ve only been in the business for a couple of years now, ADF has taught me alot but still have plenty to learn

Shauno, good advice for those that only do short trips, are regularly towing heavy loads, or spend a lot of time off road, however you didn't mention that a good quality filter is just as important as the oil itself, along with the oil change procedure. Best to drain oil with a wamr motor, as the oil will drain easier. Once refilled to the full mark, start the motor, let it run for 7 to 10 seconds, then turn it off. Wait a minute (for the oil at the top of the motor to drain back to the sump), then check and top the oil level back up. My X5 BMW is serviced every 20k to 24k, service book recommends 24k. It has done over 400,000ks without an issue, however I don't take it far off road these days, or do a lot of long distance towing with it. Most of the time it is driven, it is in a country town, dong 15 to 20 minute trips so it gets warm every time. Oil changes are easy, oil is still quite viscous (still turns as black as every other diesel), yet never had a major issue with it. However, it also uses 7.4 litres of oil, so I'd say the actual oil capacity has a lot to do with the longevity and service intervals of the oils. Trans, transfer case and diffs have never been touched since I had it, they were last serviced in a dealership and don't need to be touched for another 30k or 40k. But again, I'm not doing water crossings and such every few weeks, so those depends on your driving conditions and the overall conditions of the seals, bearings etc. Each to their own, all comes down to how the vehicle is used.

On my Gu Patrol I usually change the oil when the shops have 10w40 on special! Usually around the 5000-8000km mark but it doesn't get driven hard so I'm not fussed.

[@smarty_7997]

I’ve always held the belief that fresh fluids are cheap insurance for keeping very expensive components in good condition, especially in modern common rail diesels. I live in the NT so I do heaps of km’s per year, servicing my Landcruiser Ute gets expensive. -engine oil 5000kms -fuel filter 5000kms (dodgy outback servos) - fuel system lubricant (5000kms) - diff oils 20,000kms -gear box oil 40,000kms - wheel bearings 40,000kms - coolant every 12months (gets hot up here) - brake fluid every 12 months Keeping my Ute serviced and in good nick could be a matter of life or death up here in the NT, she does some very remote work with little to no back up. Never let me down though 🤞

[@SeriousSchitt]

I’ve found it to be the complete opposite way around. The longer the oil stays in my motor (usually 7,500) it starts to break down and becomes far more runny than the brand new oil, not thicker!

That may be diesel in the oil

Helps keep the tractor running smooth and hopefully for a very long time to come. Tow a camper when I head away so always want to make sure basic things are in check.

Changing the oil more often will lower the soot load, for sure, which will show up on the paper, however for anything else you need a proper oil analysis. Also oil has three functions, lubrication, cleaning AND cooling.

[@bartismoellis1052]

something else that needs to be taken into account on your oil changes is time if your 4x4 sits for extended periods the oil might time out before the milage interval. Engine oil can become contaminated by things like moisture just from sitting requiring a oil change.

[@electron-1979]

That's what they say, but moisture evaporates when engine get to operating temp, so there must be another reason 🤔

[@toddrohrlach8336]

I have a 2010 Hilux and do all the servicing on it. I did some testing myself and found 6-7000 still good for me. The Magnatec oil holds up well and does a great job like all Castrol products. Just did tranny oil and filter on weekend 25000ks on Transmax and no bad smell still drove well. Good test man.

[@heathwellsNZ]

My dad was a mechanic all his life and only just retired mid 70's a year or so back... from the day I got my first car and 4WD he made sure I did an oil change and filter every 5,000K's and I've stuck to that. A career's worth of experience from someone's opinion I trust (my Dad) is too hard to ignore.... and he worked on all types of vehicles including being the manager of a Landrover (series ones in the 70's and 80's) dealership/agent too... I have had the luxury though over most of my adult life to get filters and oil much cheaper via his work buying power. To this day though (even now I have to buy oil and filters retail now) I do my modern petrol SUV daily driver vehicle at 5,000K (about every 6 months)

[@kovalenkoihor4325]

5K miles or kms?

[@marcusbarnes5929]

Best to get an oil analysis to check TBN number at each service interval to find out oil condition. No point changing of oil is still in good lubricating shape...the higher the TBN number the better. Oils that are A5 spec are long drain intervals. Viscosity is important thicker isn't always better as most wear occurs at cold start up. 5w30 or 5w40 is suited for most climates in Australia for modern engines.

[@archygrey9093]

[@theroyalcrownedtiger2946]

10k km on full synthethic can be done. But 10k km on regular or semi syhthetic is not to be done. I do my oil changes 5k kms on full synthetic, so its 2 oil changes a year, which will help keep the engine better lubricated and cleaner, and reducing the wear, which helps to extend life of the engine. Oil changes are cheaper than engine replacements or rebuilds.

The engine see's new oil and an oil filter every 2,500km as well as a quick clean of the air filter, and I drain both fuel filters and grease the Unis and spring shackles at the same time. Every 20,000km I change the air filter and both fuel filters and every 30,000km I replace the front and rear diff oils, the transfer case oil and the gearbox oil. Finally, every 50,000km I replace the power steering fluid and the Brake fluid, two things that are often neglected in vehicles new to our workshop.

[@itsthemetho]

Changing oil more frequently ensures less % contamination that causes wear. This includes fuel and water. But there are diminishing returns if you go extreme on frequent oil changes. The other issue is the lubricant additives. Are they at sufficient levels to ensure performance? Lastly there is engine oil viscosity. With multi grade oils they can shear down and become less viscose. Additionally oxidation can cause oil to thicken, forming sludge and varnish. I haven't seen an engine die from frequent oil changes though, but plenty with issues related to lack of maintenance. This includes a lack of oil. What isn't discussed is oil filtration. Synthetic filters can filter smaller micron particles that are the leading cause of engine wear.

[@kevinoverdevest8022]

Went on a trip of over 2500KM and required 1lt of oil on an engine at the destination. Was rather concerned about the oil consumption as the engine had only 60K km and was 5k km short of its required service. found out it was due to contamination oil due to city driving then long distance driving. Had a service done and was recommended to replace the oil in between scheduled services (@7.5k km), since then, it has never consumed any oil and the engine has been a lot healthier. Having a scheduled service by a mechanic is good, but changing the oil myself and having a good look underneath whilst doing the oil change, has given me a better understanding of the vehicle. Would love to see an episode on fixing squeaky suspension as it seems a lot of duel cabs suffer this!

[@danmaldet5391]

Shaun, I drive a 2002 4Runner with the 5VZ-FE and it is specifically a tourer and camping rig. It always carries my gear and tows my camper. I only drive it in the summer here state side, so it usually gets around 3,000 - 5,000 miles every year. I'll typically change it once towards the middle - end of summer with 5W-30 full synthetic. I also check the diffs, transfer case, and auto transmission, coolant, and power steering every year and change that fluid every 2 years. It is almost due now but when I get back from my trip I'll be servicing the diffs and t-case. My change frequencies usually go by time interval instead of mileage.

I think a lot of this depends on how you use your car. Like he says, if you're doing lots of hard off-roading or stop start city driving its probably better to do shorter intervals. Personally for me, my car almost never sees an unpaved road and spends about 75% of its running time doing easy highway miles, I'm happy to go 10,000k between changes with full synthetic and have never had an issue doing so.

[@exploringsydneyandbeyond9059]

On our 2020 NX Pajero , from brand new we fitted a catch can , every 5,000 km oil and filter is changed with full synthetic 5w-30 that’s DPF approved , front and rear diff oils every 20,000km and auto transmission and transfer case every 40,000km . All the servicing is done myself and I only used quality oils that has the approved specs required by Mitsubishi. My oils are changed out before even half of the manufacturers recommended intervals are reached . Oils are the life blood of our cars , just like blood in the human body , the cleaner it is the longer we live , so we can enjoy our 4wds and trips even longer .

[@rondhole]

it is in the manual handbook. 10k miles only in normal condition, not offroad, high load, towing, short trips, dusty area, etc. Those harsh condition need 5000 miles interval. Actually, oil thinning up as it is used instead of thicker until it is oxidized and start slugging.

I have used Castro Oils since the 70’s in petrol engines and still do, from 84 I started with RX Super in my diesels at 5,000 k intervals with a filter and every second change a can of flush added. Since Magnatec was released I have used both types diesel and petrol at 5,000:and 10,000 depending on the driving done and a can of flush at 10,000. The gear box,transfer case and diffs usually at 20,000 but always before a major trip. Universal joints greased at 10,000. No failures.

[@jackdibella6838]

As already commented, correct spectromatic oil analysis is the most accurate way to monitor your oil properties and henceforth engine condition. Assuming this is oil from a diesel engine, oil total base number (TBN) and total acid number (TAN) are a crucial factor. As your oils alkaline reserve begins to deteriorate due to the combustion process, an acidic environment may result. Acidic environment=bad times Joe.

[@kymhanlin9930]

The only way to accurately tell what your oil change interval should be is to get an oil analysis done preferably a few times over several changes like the big trucking companies do. That way you can look at soot loading, diesel contamination, viscosity etc. I do that with every new vehicle I own and with my current usage the suggested 15000km service intervals are doing just fine. But 90 percent of my driving is long distance bitumen too which no doubt helps extend oil life. Everyone is different though and mileage will vary.

[@5975ami]

I also change oil at 15,000 km (turbodiesel CRDI, fully synthetic ACEA C3) although the recommended interval is 30,000 km. So far no problem.

[@callumrose9605]

I got 2, 2wd 2000 VW golfs. Both are lifted and got big tires. As they are both well over 300,000kms, one at 321, the other at 460 I change my engine oil at 5000km, the diesel soot, being older high mileage vehicles and drive like they are stolen helps to keep the engine going. Transmission fluid and fuel filters are done every 20k as the engines and trans work harder pushing big tires around, especially offroad.

[@shanebutler9260]

Righto. Oil service intervals: - Engine every 10k (15k in the book) - Gearbox oil at 60k (240k in the book) - Diff oils every 60k (240k in the book) My ranger isn’t used “hard” for 4WD or extensive towing but it does get some work. It’s also important to understand the rangers are known for transmission issues so for me, changing the driveline oil every 60k versus 240k as per the book is a must for me. She’s also due for a transmission service with a full flush (and potentially an aftermarket cooler at some point too!)

[@leighbaragwanath]

I have a 2002 kitchen variety Landcruiser 1HZ105 manual & it’s approaching 350K kms. I’ve always been a stickler for changing my oils on all the vehicles I’ve owned Shaun & not just the engine oils either. There is a lot of good advice in what you say . As a hunter/fly fisherman I’m away every couple of weeks for a few days at a time & many of the places I travel to demand reliability in the vehicle. I currently use the Penrite products, although am alway looking at other quality products that may assist with my vehicle reliability goals. A tip or extra little thing I do is place small magnets on my sumps & oil filters & swap them over at every oil change, just to assist in preventing my engine wear. I also use extra friction additives in the lubricants for added peace of mind & enhancement. So as you can see I take pride & care of my little Penguin because it matters.😊

[@alexanderlittle358]

I own an old diesel (rd28 gq), so I religiously change the engine oil every 5000kms. The gearbox, transfer and difs get changed every 20,000kms (or when they are too contaminated with water/other contaminants). Coolant gets flushed and changed when it shows up bad on a test strip, and brake fluid gets changed when the pads are changed/when the fluid goes black. All fluids get check rather often, particularly before a big trip, and changed if necessary

[@nicholascaraiscos4162]

service intervals Engine oil: 5000km oil filter: 10000km Gearbox fluid and filters: 20000km diff fluids: 20000km transfer case fluids: 20-30000km Change fluids around the vehicle frequently as vehicle gets pushed heavily through mud and water crossings all year round. Frequent fluid changes ensures there is less contaminated fluids in the vehicle at any stage.

[@lukepell3871]

All those cooking segments definitely works wonders for your spooning technique.

[@tiputipu777]

The recommended oil change intervals are mostly based on normal highway driving and also run time. If you mostly do hard 4wd for lets say 5k you might easily do the equivelent of 10-15k of normal high way driving. The more highway driving you do, in theory the more ks you can do before an oil change. I forgot to change my diesel kia ceed oil and went 27000ks on the same oil. 327000ks on the odometer and still doesnt burn oil. For regular cars I change 15000 to 20000, for my hilux I changed every 10000. Also diesel suts the oil very quickly, and especially a diesel with over 400tkms you dont have to go long before the oil is black. Diesel works as a lubricant so in theory you can get away with a bit more ks between oil change vs a gasoline car.

Manufacturer doesn't just recommend changing the oil every 10K but also every 6 months for Honda as an example or 12 month for other cars. So basically some people may not even do 5k or 10k during 6 months but according to manufacturer they need to change the oil on which ever comes first

Our LN106 is serviced every 5000-7500km's, new oils all throughout, it does alot of water and mud driving, aswell as towing. On a fresh rebuilt motor we try our best to maintain regular servicing. After about 2500 kms the oil is still clean enough you can see through it on the dipstick.

[@vnyeu]

1, Oil became dark is because of oil stick on the side of piston. Oil get burn after combustion. Piston move up and down which contaminated that some carbon push through the gap which mix carbon particles into clean oil. This usually in deisel engine due to great force 2, oil spray on piston wall which is very hot. This is just like oil get cook slowly which turn to brown.

[@vincentrobinette1507]

Another thing to consider, Forget distance travelled, forget hours of run time. I think it might actually be more accurate to go by total liters of fuel consumed by the engine. I would guess, about 150-200 liters of fuel consumed per liter of total oil exchanged in a service. You'll find, that doing heavy off-roading, or short distance winter driving, your fuel efficiency is very low, compared to summer freeway driving. Going by the fuel consumed, compensates for the variety of operating conditions the engine might be subjected to, during a service interval. I used to drive a tow truck. There was a lot of time spent, with the engine idling (jump starts), and, time where the engine was running above idle, and even loaded, (recovery), where the engine is consuming fuel, without going anywhere. Then, there's towing, where the engine has to power the weight of 2 vehicles, and all the rigging to connect the two together. That engine was always heavily loaded. The truck was equipped with a very large auxiliary fuel tank, and, every 3rd fill-up, time for an oil/filter change. Despite the severe operating conditions, the engine lasted for decades!

I have two 4x4's- a 2013 Toyota Hilux N70 1KD-FTV, a 2001 Toyota LandCruiser 105 Series with a 1HD-FTE in it and I also have a non 2005 Subaru Liberty GT Turbo. I only ever use Castrol or Nulon in all my vehicles. I have refused to use Penrite for years since it caused my Subaru and also my father's brand new Subaru Outback to tick. The first two mods that I always do whenever buying a new car is installing an Oil Catchcan to reduce blowby particles of oil clogging up my intake and cleaning the intake manifold and EGR components, and then blocking it off. After that, I will install a pre fuel filter and diff breathers. I change my engine oils and filter religiously at 5,000k's, regardless of what vehicle it is, I also do my fuel filter at this time. The EJ20 found in the Subaru is a extremely finicky and highly stressed engine and they like regular oil changes with premium synthetic oils, where as I use the recommended semi-synthetic oils for my 4x4's. I change my transmission, transfer case and diff oils after every hard trip, especially with water crossings, if not, every 15,000. I use the Nulon Ezy-Squeeze for this, primarily for the easy and convinience of not having to lay under the car getting a sore forearm from using a small hand pump that only transfers small quantities with lots of manual labour. I do power steering fluid flush, brake fluid and coolant as it is required, when there starts to be discolouration, a drop in levels or slop in the brake pedal. Cheers Shauno, loved the video. It just further reinforced that what I have been doing truly is cheap insurance and the right thing to be doing!
