I really like the Valvoline MaxLife high mileage oil, and use it in a little 4 cylinder Grand Am that gets well abused by a 17 year old driver. The MaxLife is a nice, robust blend that performs well for the money. I wouldn't think of using a different oil in that engine, I'm that pleased with the MaxLife.
In the past, I have used the blue bottle DuraBlend, before I went to using straight synthetic in that vehicle (Penn. Platinum).
I don't think I've ever bought any of their conventional white bottle oil, or any of their synthetic. Just the two synthetic blends.
