This is from the wife's van. She does not understand terms like warm up, drive moderately, or check your oil. She is a very aggresive driver. Daily commute is about 50 miles with about 25% city driving.

It's odd to see a SJ dino oil with Moly .

What was the previous oil used ?

Low Iron there

more convincing to me once again that no syn oil produces as good of results in the good ol 4.3 as a basic dino (good quality of course) does.

Dont understand why this is, but more and more I can not justify using m1 or any other syn in the 4.3 when pennzoil, superflow, etc work so well.

I have GTX start-up in there right now and cant wait to compare!

Seems like a high Pb ratio (and total # for 5000 miles). Is this normal for the GM 4.3?

The prior oil was Valvoline High Milage.
This is a very typical UOA for this motor.

You are probably correct, but I always thought the formula is:

No warmup=my wife

sorry couldn't resist.
