Thank you for sharing the UOA @HLG600 and note that some dealers could use these oil treatments against you as the warranty specifically states MB 229.5 spec, with no mention of additives as they can't guarantee the life of catalytic converters and important emissions equipment with those products (not common, but still possible if there are warranty issues). Parts of the oil additive package can also see this as an impurity and you'll deplete important dispersants, detergents, etc. as the oil can't determine this as a positive addition, only as a contaminant.
Nothing against Project Farm, as I enjoy his content, but that Ceratec test means absolutely nothing with regard to how the product applies to these engines.
Think about it, who rates a product to work for 30K+ miles and recommends an oil change to go that far?
In any case, I tried Ceratec on a few vehicles and at this stage will likely not use it again. The M113K will be running on Liqui Moly Leichtlauf 5W-40 and the M156 on Motul X-cess 8100 5W-40, both supplemented with Liqui Moly MoS2.
this ^^^ - don’t get me wrong, I think Lubromoly makes fine products. I just don’t think Ceratec is meant for every application. I’ve read on certain things that it doesn’t play well in certain temperatures. I am a believer that if it isn’t broken, why fix it?
I live in Miami - and that is incorrect. 5w-40 is used at the dealer because of what is mostly available at the service/parts department. It has been discussed widely in other threads as well.
Also, all 6.3 (that were used at the private mag events) as well as the GT3 (current program) engines use European blend m1 0w-40.
To some people it does not work and they use 5w-40, to my car 0w-40 works beautifully without a single noise of lifters.
As a side note, 0w-40 will gets to locations quicker than 5w-40 will - this is where the majority of the damage of any engine would make sense in any start of an engine, how quickly oil can get to those locations when the car has been sitting.
Was at the MB dealer of Westwood this morning picking up a serpentine belt. I saw shelves full of MB branded oil of different viscosity. I asked how much 0-40 was and the sales rep told me they didn’t carry it. Asked what the techs used for AMGs specifically. He said 5-40 for all AMGs including GTs.

That, and there's also the subject of spark plug glazing which has been brought up in the past regarding Ceratec. Once every 30K miles when considering a 60K mile spark change interval is one thing. But every oil change now?

Please do share. The more UOA data available the better.
