Using Euro PCEO in 3.0L babymax?

[CANADADIY]

As per above, I kinda wonder now...since wear metals went back up. The only variable was that I went to Mobil 1 ESP 0w30 for this run.

But there are more variables than one. Don’t base your decision off one UOA

That’s not the only variable. Everyday driving is rife with uncontrolled variables.

It’s most likely that the oil had nothing of significance to do with the change in the analysis

Same filter, same use...no towing or anything other than normal home/work/home trips.

Nothing out of the ordinary. Heading into summer, so maybe a bit warmer vs a bit colder...but I live in a mild climate (VA).

I had some Castrol 5w30K left over from before and my prior UOA on it wasn't great. To see if it is a break in issue, I used that for the current oil. If the numbers come in different than the run of 5w30K before, it should point towards break in vs oil performance.

After that, I am thinking about going to a Dexos D 0w20, probably Mobil 1...and just staying there if it tests well.

But even just changing oil can cause additive packs to compete. Better to do a UOA after at least 2nd run of whatever oil you've changed to.

Your iron wear went up by less than 1ppm per 1k miles, but your titanium dropped noticeably, which could be from things like valve spring retainers or wrist pins. You also need to run 2 or 3 oil changes before all of the old oil chemistry is out before the new oil chemistry is in there exclusively.

This UOA doesn't prove much, if anything

Or the Castrol
