Anyone have any experience with this oil? I was in Carquest the other day picking up a serpentine belt for my truck and decided it was about time to do an oil change as well. I usually never buy stuff like oil at Carquest because they're so expensive, but anyway, I found this oil on the shelf and looked on the back and it says it's made by Ashland (Valvoline). So am I to understand this is probably Valvoline SynPower with a slightly weaker add pack? It is still SM GF-4 rated. I went ahead and bought a case along with a Carquest Blue (Wix) filter and changed the oil in the truck. I'll probably run it 6 or 7,000 miles and do a UOA to see how it does. By the way, I picked it up for $3.69 a quart, that's why I bought it....pretty good deal I think if it turns out to be a decent oil.
