My first share of an oil analysis. Here goes:

Comments appreciated. Thanks!

Was it the semi-synthetic or the full synthetic 5W-20?

 

[saberz]

Title indicates a semi synthetic was used. UOA looks really good.

 

[gd9704]

It's the Semi. I made a point on the submission form that it was the semi version, but the report says "synthetic."

With that TBN, you could easily do a 7.5k run.

Nice results!

Great report. Not much differnt than my Explorer with the same engine and PP 5w20. Says alot about the engine with that kind of consistancy.

Is this made by Conoco?

If so, is it the same oil as Trop-Arctic Semi-Syn? It looks like it!

 

[zulu]

Yes it is a Conoco brew.

FWIW, your GM will run forever on this combo. Insolubles were creeping upward so I wouldn't stretch it too much further. Looks good.

Lots of boron, wonder if that has a lot to due with minimal wear.
