That is not an oil I would use personally, but you can't argue with results. Changing the oil is much more important than what brand of oil you use when you change it.
That said, I use only Valvoline motor oils in all my vehicles. Period.

I'll second that motion; it's the neglect that really kills a vehicle. Plus, we know synthetics are better than conventional. Therefore, I change mine with Mobil 1 every five thousand miles, and the other car gets Pennzoil synthetic at the same interval. Both run like a champ!
