Looked at all my gallon jugs in the garage and 3 are STP 5W30. So I have done at least 3 oil changes on the wifes Buick that is at 320,000 miles. It has always gotten the inexpensive stuff so Delo 400 and Chevron Supreme. But I think Autozone had a package deal of but 1 gallon and get a STP oil filter free.
I will not use it in my Subaru Outback XT's turbo.
