Mobil1 0w-40 European formula and DIRECT INJECTION



With reading on another post about a weird noise I thought I would post this for everyone since I already switched my engine oil.
I stumbled across this video last night from Lake, the motor oil geek.
He STRONGLY advised to not use the mobil1 0w-40 European formula in any direct injection engine based on his findings.
Here's the video for you all to view yourselves and make the decision on your own.
I've already switched to LIQUIMOLY MOLYGEN and happy I did after seeing this video. He has also been endorsed by Dave from Dave's auto center for his research.
Watch the video and decide for yourself if you'll keep running the mobil1 0w-40 European formula in your direct injection Mercedes.
Hope this helps!

Thanks OP for the heads up!
The video used is the older formula of Mobil 1 0W-40 Euro. The newer one I believe started appearing on shelfs since 2023 is API SP rated.
That said, there are better oils than Mobil 1 in general, in fact, we had quite a discussion on the oil pump solenoid thread.

Pennzoil was one of the many oils discussed in the oil pump solenoid thread indeed and also one of those I too will recommend.
Thoughts on Amsoil? I heard very good things about them too.
Otherwise there are always recommendations for Liqui Moly.



I've heard good things about the Pennzoil and Amsoil. I follow Alex from Legit street cars and that's all he uses is Amsoil. And in the flip, Samcraac recommends Pennzoil in his videos.
Since I've switched to the new generation MOLYGEN 5w-40 I've noticed a decrease in overall engine noise and a 1-2 increase in MPG.
I'll be on my 2nd full oil change of MOLYGEN this week. Planning to do an oil and filter change before my road trip upcoming at the end of the week.
I wanted to bring this to light and raise awareness for anyone running the mobil1 0w-40 European formula! Like @JettaRed said most modern cars are direct injection.

not denying amsoil is great oil and chris is a great guy (he is pretty helpful on the forums answering forum member questions. I just admittedly have no experience with amsoil I would consider them in the future though, and I mean, I do also trust LegitStreetCars, he was also an mb tech back then.

The manufacturer themselves do not recommend Molygen for some reason, read more in that thread.

I still didn't see it on the approved list but only time will tell. I am a maintenance nut and change my engine oil every 3-5k miles.
I intend to keep running it due to the additive formula and not wanting to keep changing oils. I had a noticeable difference that I posted a video on regarding sound DECIBAL readings, vs mobile1 and molygen. There was a 2 DECIBAL decrease from the mobil1 to the MOLYGEN.
I also Had to change my valve cover earlier this week and did an inspection while I was in there. I did not notice any wear, glitter, or anything out of the ordinary while doing that job. All the cam lobes looked perfect as well.
I will update the team when I do the oil change this week. I can inspect the oil and filter for wear particles.

It is a good thing that a new formula actually improves things for both Mobil1 and Molygen in this case as that is rarity in my experience lately.
Dishwashing detergent that is advertising a new formula contains more water, then there is salad dressing advertising new formula I found the taste much worse and the quantity also decreased. Then there are all the other products that said new look new packages which is really to hide the fact they downsized.
Since we are on an MB forum, in forum member streamliner's experience, the W223 E-ABC suspension was apparently inferior to the previous option in the W222.
I wish these products mentioned can stay true to the if it ain't broken, don't fix it.

Appreciate the info!
Ant
and the reason I keep mentioning it across many threads is because I believe good things are worth sharing.
My experience with unplugging has been extremely positive with absolutely no downsides.
I hope you can benefit from this mod and that your engine is applicable since I believe no one did this on the M271 yet, hence why I recommend doing oil pressure testing manually with gauges to make sure it behaves the way it behaves on the other MB engines.
