Here's my fourth UOA on my 2010 Buick LaCrosse CXS. Sorry I was remiss in posting this UOA for a sample I took over a month ago.
Results for this UOA are on the left side and the results from prior UOAs follow on the right. Please note that the prior UOA performed was on the current oil change back at around 50% OLM and this current UOA was done when the OLM hit 2%.
Engine Model: GM LLT 3.6L V6 Direct Injected
Oil: Pennzoil Platinum 5w-30 Synthetic
Oil Filter: Purolator PureONE PL12222
Miles on Oil: 10,569
Miles on Engine: 42,067
So looks like we got a bit of a surprise with this UOA revealing that the oil contained unwanted high levels of water. Really don't know how that happened, but I'm certainly looking forward to the next UOA to see if this is a trending problem. Anyone have ideas on how this can happen?
Aside from that, it doesn't seem like this brand of oil garnered better results in lowering wear metal contamination. So for this time around, I just used the oil I happened to have a case of in my garage which was Mobil 1 (the non EP flavor this time).
As usual, I appreciate any feedback and advice you all have to give.
