[@SediciTurbo]

Motul in its catalog recommends 8100 5w40, in my city the ambient temperatures range between 0º and 40º in winter or summer, it must also be taken into account that my car is modified and it would be ideal to keep the oil pressure stable in conditions of maximum demand with a lot of heat.

[@TcheCaver]

You should make a list of things that need to be maintained on B58 2/3/440i's, and at what mileage/how long to go between service intervals. As a 340i owner, there is so much conflicting information about maintenance, having you break it down clearly would really help!

[@kern417]

I'll definitely try to do that in the future.

[@Oni-One]

@@kern417 Yes, please !

[@AgonxOC]

Service interval should be between 5K - 10K miles/1 year, whichever comes first. If you drive the piss out of it then 5K, if you driver normal around town then 7.5K, if you drive on the highway a lot then 10K. Do not go beyond 10K and also keep an eye on the oil temps and that will give you a good relative idea of how the oil could be performing. My N55 starts to burn oil between 6K and 8K, which is my cue to change it. The engine has 163K miles and it runs like it did when new.

[@mannisingh4950]

@@AgonxOC Yup this right here. I follow the same rule, once I start burning oil or get a low oil level light which is usually about every 8-9k km I change the oil.

great info. I actually made the switch from 0w-20 to 0w-30 Valvoline European bmw ll-01. I do some spirited driving twice a month, and burn less oil than when I was running 0w-20. Before I had to top off about .5-1qt every 2k or so. The most I had to top off was maybe half a quart at about 4k. 0w-30 and 0w-40 for the win all day!

[@MatthewWatches]

Weather is important, living in Florida are summers are very hot, I run 0-30 in my xDrive 440i, no issues, the slightly thicker oil helps combat overheating, heat thins oil and when it's already very hot it can get too thin at 0-20, all shops in hot climates suggest *-30 for summer, most of us running year-round.

[@kern417]

Weather doesn't matter. Our cooling system works well whether it's 30F or 100+. And thick oil doesn't combat overheating. You need to improve your cooling system for that.

[@suspect3539]

Before watching this, I had 100% convinced myself to move to a 0w-30 or 40 on the next change but what you say here makes perfect sense. My oil temp stays rock solid around 230 even during extended highway runs and the car has under 50k miles on it too, so definitely no reason to go up yet. Thanks as always for sharing your extensive knowledge of these cars.

[@ZoneCrasher]

0W-20 was purely developed for fuel economy. 30 is always the better choice for wear protection as the film strength of 20 oil is compromised.

[@kern417]

Correction. The car was designed to run on 0w-20 to improve its fuel economy. Running the correct oil is always the better choice because running an oil is too thick can cause damage. You're welcome

[@ZoneCrasher]

@@kern417 If you look at the manual closely, it says 0W-40, 0W-30, 5W-40, 5W-30, 0W-20 or 5W-20. BMW recommend 30 or even 40 weight for cars sold in Europe, that should tell you something. 0W-20 is to meeting EPA fuel economy requirement but at the expense of engine wear. You heard it from me first. 😄

Amsoil makes a wonderful "European Spec" 0W-20 and an even better Signature Series 0W-20. I probably wouldn't use sig series until after yanking the stock cat off like you did. Those European emissions/cats are no joke.

[@Hubscharber]

The problem with Amsoil is that: 1. they're effectively an MLM company and 2. they don't go and get the approvals from the manufacturers

[@TheMrwinkleberry]

I was curious about this. I swapped from BMW oil to Amsoil Euro 0w20 as soon as I bought the car. I have since went catless with a stage 2 tune. I wasn't sure if it was ok to switch to Amsoil Signature 0w20 or maybe even 0w30 on my next oil change?

[@ianlam1445]

I live in Australia and summer is approaching it usually hovers around 35-40c for ambient temperatures in prime summer. We have an Australian branded oil called penrite built for Australian conditions. What would you say to be using 0w-30 or 5w-30 full synthetic with a gen1 b58 at 100k kms and running stage 2+ BM3 tune and downpipe with supra HPFP installed.

[@kern417]

Should be fine

[@to6ko9913]

Hi, this oil is for NA only, what is the equivalent for the EU market?

[@mokotoks]

Great advice and well thouht out and clear. The one thing I still puzzle about with mine (2017 B58)is that its even lower mileage and not driven much in the winter. I end up getting the maintenance advice to be done annually and not on mileage. I am being told that spark plugs are due at 25,000 km because its at 5 years. It seems too soon to me and if anything I think I will remove the plugs and put them back in just so they dont get stuck from being in too long. OIl changes every year isnt a big deal to me but even then its very low mileage between intervals. Any thoughts appreciated???

[@kern417]

A lot of fluids need to be replaced regularly regardless of use because they absorb water and contamination even when not running. Spark plugs not so much but they can still rust or just get old from sitting. It's still a good idea to replace. Even tires dry rot over time even if the tread is not worn down.

[@mokotoks]

[@kern417]

Nope it's pretty much the same, but fitment for some parts like the intake and heat exchanger will be different just because you have a bigger engine bay. But turbos, downpipes, etc that bolt to the engine should have the same fitment.

[@sleeper3404]

Thanks, kern417. I’ve got a lot of knowledge from your channel about basic technology and mod for B58. Recently I changed oil by myself. I chose ‘Liquimoly synthoil 5w-40’ than ‘Leichtlauf 5w-40’ ,because ‘synthoil’ is advertised as ‘fully synthetic’. But ‘Liquimoly synthoil’ is approved as ‘BMW long life 98’ , not ‘BMW long life 01or 04. Do you think it will cause any trouble? My 340i is tuned by MHD and xHP, catless downpipe, CSF heat exchanger, tuHPFP. MHD setting is ‘stage2 98ron, sport cooling mode’. Oil temp remain under 100°C under street use. I have two questions blow. ①Does ‘BMW long life98 approved oil’ cause an issue on B58? ②’MHD stock cooling mode’ keeps my oil temp around120℃ @10℃ ambient temp. ‘Sport cooling mode’ keeps it under 100℃. Which mode is better for street use?

[@kern417]

I would recommend switching to the LL01 oil at your next oil change

[@kern417]

I don't use sport Cooling mode personally Because I don't see the need. My oil temps are controlled well without it on.

[@sleeper3404]

Thanks, I appreciate your advice.

[@joecastro23]

Why wouldn’t you recommend LL98 if that is a true synthetic oil? Vs liquimoly high tech which is a blend but advertised as “full synthetic”

Very informative video. I had experienced some oil consumption, 0W20 full synthetic Pennzoil. I didnt get a warning or anything but i always check my oil. Thinking of making the switch to 0W40, its LL01 Approved. Is it normal for 0W20 to be burned in a stage 2 catless downpipe, 91 oct B58?

[@kern417]

Not in my experience but every car is different. I currently run 0w30

[@aleksankazakov]

The reason for 0-20 oils is because of all of the modern automobiles automatic transmissions keep the engine RPMs under 2k at all times when normal driving. Note this, its the key to all of the answers about 0-20 oils. Also all of the modern car engines have short and light pistons that can not be compared with anything that was made in 90s Understood you may race once or twice a week for a brief moment but most of the time your car spends under 2k RPM when normal driven. Why is this important? Because when you drive normally your transmission keeps the RPM low to reduce emissions and increase fuel economy but with it, the actual STRAIN AND PRESSURE on the piston is MUCH HIGHER than if you were spinning the engine at 3-4 k RPM while coasting down street. That increased pressure combined with already light and short piston height causes the piston to wear the cylinder walls faster than it would be on the older vehicles because the older engines had a much higher piston height and higher nominal RPMs. To combat that they had to reduce the spacing between the cylinder wall and the piston, to reduce the side movement of the piston. But because of it, they needed a much thinner oil. If you put a thicker oil in the engine, it will act best under stress but while normal driving, which I assume most do 90% of the time it will actually harm the engine. BMW Engineers arent stupid.

They Saud I could ask the service dept. to put the thicker oil (0W30), or even 5W30, if I wanted, but the 0W30 flows better . Tgey also told me that the 0W20 provides better gas mileage, wich lead me to believe the thin oil was just for saving gas, but then I run into this video.

I would like to use my b58 mainly in race track even for long periods of times like 2laps on nürburg ring, drift racing ect with mhd around 500hp. 0w-30 BMW oil going to be satisfying in you opinion?

Yes

[@user-jg6md6kk2n]

What is your thought about using CASTROL EDGE 0W-40 A3/B4 for this engine? During winter time, would it be better using 0W-20 then 0W-40?

[@kern417]

operating temp is the same in winter and summer, so either will work fine. i like 0w20 and 0w30.

[@codyway7424]

Agree with what you say, but... If you read thru the various forum boards, guys who routinely analyze their oil get the best results with 0w40 or 5w40 ll-01 spec oil. Then there's the guys who really beat on their turbo engines that swear by rotella 15w40 T6, although it is not ll-01 certified. In the chart that you put up, an oil with a 3.5 High Shear Viscosity or better is where you want to be. Below 2.5 any you are asking for trouble. And remember that oil with miles on it breaks down over time, so you may loose a point after 5000 miles or so.

[@kern417]

I'm not sure where you're getting your info but you absolutely should not run 15w40. Plenty of people get good data with 0w20 as well. Stick with what the engine is designed for and you'll have the best luck.

[@codyway7424]

@@kern417 My info comes from the race/drift guys who beat on their oil pretty hard. And yes, the higher shear oils within a given viscosity do consistently exhibit less wear. This is a big reason why Amsoil, Penzoil, and Castroil synthetics generally do well when compared to the rest.

[@kern417]

You can't just go to anyone to get info because they drift their cars. Do they have B58s? Stock engines? Whats their oil change frequency? What oil temps do they see? You're talking about something that doesn't relate to the topic at hand. Running that heavy of an oil on your B58 will ruin it. All you're doing is slowing down the oil's flow when it's cold, which is when the most wear happens. Do more research and you'll understand.

I subscribed to your channel. A lot of good information that helps a lot. I use Valvoline C2 0w30 LL-12 FE, with stage2+ E30 on my 18’ 340i in Eu. I am going to change to Liqui Moly with the same specs, or should I change to 0w40 or 5w30? I don’t know what will be the best for me on stage2+ E30?

Both will work. If you will be Starting your car in sub-freezing temps then the 0w will provide better cold start protection. But 5W works great as well.

So happy I found this channel! New B58 owner. Yes I bought used but from a friend. I now see that one 0w20 is fine even tuned but noticed a lot of you guys going 5w30. I’m looking at Liquid Molly and it gives those 2 options. Why are you all going 5w30 instead?

[@kern417]

I think if you are in a climate where you don't drive your car in freezing temps then 5W-30 is fine. I also used 0w-20 then 5W40 and now 5W30 just because I like changing things and collecting data. But I wouldn't expect a noticeable difference in performance.

Trying to pick the right Liqui Moly product. They recommend 0W-20 Top Tec 6600 but on FCP Euro they recommend 5W-30 because "New BMW's fitted with BXX series engines "Require" 0W-20 LL14FE+ Rated oils. WE DO NOT RECOMMEND using this spec! The levels of protection LL14FE provides are much lower than LL01. The new formulation LL14FE is mainly designed with CAFE ratings, EPA requirements and fuel mileage in mind, NOT OVERALL PROTECTION.""

It's not ideal but probably works. I still recommend doing an oil analysis. Expecially whe using 10w oil. It'll take longer to warm up and you'll drive your car longer with the engine oil below operating temp.

No does not effect cold start at all, difference between you and me is you go through engines but I have never lost an engine in my life. And yes, most of the time I'm airborne.

@@SlickJeff2020 it absolutely will increase the time to warm up going from 0w to 10w oil. It's physics. Idk what you are going on about the rest. Like I said, do an oil analysis and it'll tell you everything instead of going off of assumptions.

[@SlickJeff2020]

To test your 0w health theory hold your hot engine in third at 25 miles per hours, than slowly bring it up to 4,500 rpm, if you look for it your gonna here metal on metal contact in your cam loops, because 0w can not provide adequate film. That's science.

@@SlickJeff2020 you really don't know anything about science or engineering if you think that's the case. Higher viscosity can't provide better lubrication if it can't get between component's.

[@sanyry1336]

Nice video. Keep going. I emailed liqui moly about what oil should i use in my m140i e30 and this is them answer: The manufacturer requires an oil with the BMW Longlife-04 specification. In the fact that this engine is not already standard I recommend to raise to an 5W-40 viscosity for stable oil pressure. Please also check your oil temperature, which should not be higher than 115°C, sometimes 120°C maximum for a short time. If the temperatures are higher, your engine will be damaged in the long term. As perfect suitable oil from us I recommend our Top Tec 4110 5W-40 with the official BMW Longlife-04 What's your opinion about this? Thank you
