Looks alot like my 4.8 v8 in 2k silverado that I ran with Pennzoil 10-30!

My UOA

Looks good.

Love my truck. Never been to the dealer for repair.

Enjoy! Bill

Yea-I think you are looking good. Hard to beat for a vehicle that is breaking in. You might find eventually the lead might need something thicker. But steady as she goes for now.

Yeah, single digit wear (oh, and that copper we've come to expect) is pretty good for an '04 vehicle still breakin' in.

"Looks alot like my 4.8 V8 in 2k silverado that I ran with Pennzoil 10-30!"

Yup. Chevron Supreme and Pennzoil are formulated similarly and look almost identical on paper ... but I'm pretty sure they buy their additive packages from different vendors.

This is the SL GF-3 version . Did you refill with same or the GF-4 SM oil ?

I refilled with GC. Couldn't pass up $3.79/quart at AutoZone. I'll run the GC thru winter and decide what to switch to come springtime.

Thanks for the comments!!
