Hello guys

I have bought a used G80 M3C, 2022 model at 10.000kms.
In the service book, it had it's break-in service made at 2000kms (1200miles)

My car shows me to change the oil at 25000 kms; i currently have 12000 kms and it is time for an oil change.

Following BMW suggestions regarding fluid maintenance would be crazy.

I want to ask you guys if I change the oil myself and filters, does that affect warranty (any marks, safety locks, etc)?
I don't want the BMW service guys to notice that I have made the oil change myself when I will go at 25000 kms and have issues regarding the warranty.

Also, if I just change the oil and filters, does the car reset automatically the distantance until the next oil change? Because I benefit of a free service maintenance up to 30k kms.

I can also book an overpriced oil change at my dealership but i would rather do it myself.

Also, what fluids do you recommend for oil, transmission etc?

Thank you!

No changing oil by yourself in between dealer service intervals will not void warranty if you use genuine or OE/OEM parts for the oil filter and drain plug. For the oil and if you planning to stay stock, stick with 0w30 BMW LL01FE certified oil.

I personally am changing with Shell Helix 5w40 every 7.5k kms because I am running on E40 mix and fuel dilution from ethanol thins out the oil considerably over time whereby 0w30 would be far too thin for spirited driving applications.

Thank you for your answer.

If I only change, without messing with the service reset, the car will show up the same distance until next oil change?

I'm not saying you're wrong, but do you have some Blackstone UOA to back this up? I'm running E30 now on OEM oil and plan to send a sample for analysis after 4 or 5k miles.

Yep I had an oil analysis test done on my F80 M3 before which was running E70 mix on full race turbos, EU5 fuel injectors and Spool HPFP.

The oil I was advised by my tuner was any high quality 5w50 with a HTHS of above 4. I put in Mobil 1 5w50. After about 4.6k kms on the oil, the oil degraded in viscosity to between a 0w30 to 5w30. So because of this I would think that E30-E40 mix would degrade a 0w30 to about a 0w20 or less within a couple of thousands kms. Beating on a tuned car at that thin of an oil at high rpms is not healthy at all

Not entirely true. Under the Magnuson-Moss Act, a manufacturer cannot force you to use their parts or services. Here's the FTC's take on this: https://consumer.ftc.gov/articles/au...vice-contracts Every owners manual will have a list of what types of oils and viscosities are allowable. Once you make the decision to run other types of fuel in an engine that was designed for straight petrol, you're screwed anyways. Link just in case anyone wants to see the explanation behind the thinning of oil in ethanol applications. https://www.enginelabs.com/engine-te...ur-engine-oil/

How many of you have actually checked the warranty requires and associated laws for Romania, where the OP is located?

Doing an oil change yourself while using an acceptable oil and without screwing anything up should be undetectable, so no need to worry about warranties.

A manufacturer can most definitely void your warranty if you are using aftermarket parts. For example, if put on aftermarket shocks that reuse the factory top strut mounts, would 100% void the warranty for the factory top strut mounts if the top strut mounts somehow prematurely fails. But if you use OEM or OE parts for the shocks which are made by Sachs, then your warranty will be intact. Same with engine oil and engine oil filters, if you use an out-of-spec oil or an aftermarket oil filter (don't think there is even any for the s58) for the engine, your warranty will be void. If you use an OEM or OE equivalent oil that carries BMW LL01FE approval then BMW will have a harder time proving the oil was the cause of the engine damage since it has the approval. Like filters as well, if using OEM filters such as Mann, Hengst or Mahle then the warranty is intact.

That’s just not true. They can not void your warranty or force you to use OEM parts. That is illegal. I don’t know where you people get your information from.

Yes they surely can void your warranty if you use aftermarket parts. Case in point earlier, aftermarket shocks have faster rebound and compression which accelerates wear on the factory top strut mounts. BMW can argue that the aftermarket shocks accelerates wear on the mount as those shocks are not intended for fit for purpose in combination with the factory top strut mounts. They take it to court, any decent magistrate would see the case as in BMW's favour and your warranty is void. This is the same with engine oil and oil filters, using an out of spec oil and/or aftermarket filter can be easily proved by BMW in not providing the right oil lubrication and filtration for the engine. Again, any decent magistrate will fall the case to BMW's favour and your warranty is void.

So I have searched EVERYWHERE in Romania for the stock 0w30 LL01FE oil and i could not find it.

However I have found the versions of 0w30 LL04FE and LL12FE available.

What is the difference between them? They noth appear as recommended by the manufacturer for the S58 engine

You would want to get the oil change kit with this part number: 11428092620KT

I believe LL04FE is strictly for the EU but isn't allowed in the US and some other parts of the world. Anyways, LL01FE is superior to the LL04FE as it has a higher TBN and higher SAPS content. I would go with LL01FE over LL04FE if you can get it.

I think 01 can’t be found in EU. And we have 04 and 12.

So I have done some research on the subject and aparently 01 is better if you use gasoline with lower octane number than E95.
In Romania I run my M3 on E95 and E98 so LL04FE or LL12FE should be fine. I will change it in the next 7500 miles anyway.

I have also spoke to BMW service guys and some of them told me they replace the stock oil with 0w30 and others replace with 5w30.

What s your opinion on 5w30 for the B58 engine?

Thank you man!

You may be right for Australia, but here in the U.S., they cannot do that. It's not my opinion, it's the law. The Magnuson-Moss law was put in place to prevent manufacturers from forcing you to use their services or parts. As long as a part meets the same specs as OEM, you can use the part without voiding your warranty.

Don't know much about the b58 but they also specify for 0w30 and 0w20 for the b58tu engines. I would stick with LL01FE 0w30 in Winter and LL01 5w30 in summer. Romanian winter does get pretty cold and a 0w would provide better cold start flow and protection

You can change your oil but make sure you have proper documentation. Id buy the filter from the dealership and keep the receipt for the oil.

Mines included, but Ive been getting coupons for $150 at my local dealer. Filter, oil, mess.. I'll pay the $50 extra then subtract a free coffee, couple snacks and change of scenery. $40 extra lol Money well spent.

[davidmct-M3]

Had an interesting challenge in the uk. Phoned a number of dealers to get the oil changed at 9k miles (CBS is 18k miles in EU). All but one said not possible and would reset the service interval. I wanted it done off cycle as I have the service plan.

After being reassured several times that changing the oil wouldn’t impact the CBS I arrived at the garage to be told that it would not be possible. They said all changes would have to be registered in the system for warranty purposes. Not only that, I would have to pay for it and lose the 18k oil service.

My choices are now
1. Use my indi who probably has never done an M car before
2. Do it myself but would be a first and no way of getting car raised and level high enough to do it.
3. Leave it to CBS.

Any other suggestions welcome.

Unfortuntately you are misinterpreting the MM Act or simply passing along your interpretation of what someone else told you. I spent many years with a major automotive manufacturer (some of that time spent denying warranty claims) and have been in the car business for 32 years and still going....

The MM Act was written to keep a manufacturer from voiding the warranty on your car if you got the oil changed somewhere else or used an aftermarket oil filter. It was not written to allow people to modify their cars willy nilly (even though that's my preferred method).

A manufacturers warranty, which by the way is not required / they can all just say, no warranties anymore on any cars and there's nothing anyone can do about it, is specifically designed to cover DEFECTS in MATERIALS and WORKMANSHIP. That means if a part installed at the factory goes bad then they will put on a new one or if they screwed the car together wrong they will screw it together correctly, within the stated time and mileage. That's all it covers. So if you change shocks to Ohlins, they are not covered under the factory warranty anymore, but of course the manufacturer cannot deny your warranty claim on your air conditioning because you changed your shocks, in other words, they can't prove (a better word today is associate) that shocks would affect AC failure.

The issue today is one that didn't exist in the 70s. Oil specs are not just 30 weight or 10-30 anymore. Now they are LL01, Dexos, and all the other 10's or 100's of very specific molecular structures. So yes, that is the new OEM spec and if you decide to run 15-50 Shell Rotella and they figure that out, you won't have an approved warranty claim when your rod bearing seizes. Of course, if you are only running a different oil to accomodate E85 usage, I am sure you have already come to terms with having no powertrain warranty considering the tune already has the engine (and rest of the powertrain) operating outside its designated parameters and handling more torque than the engineers designed it to handle.

As soon as my 1200 miles is up, I will get the break in service done, I'll drive it home, pull the ECM and send it to FEMTO and the car will not see the dealership again as long as I own it unless the radio goes out. The difference is I won't be calling BMW in denial pretending my car is stock hoping they fix the powertrain I blew up for free.
