Think Havoline makes excellent oil, it's just nearly impossible to get here...sold by one store (PatsSource), in quarts ONLY, for like $6 each. No sales either on it...
I use it an no complaints here. One of the best "sleeper" oil and it goes to show a lot of folks that even "regular" conventional is a darn good product. It kinda hurts that "extra insurance" argument.
I would like to know the Havoline Syn testing results (it holds a lot of the various man. specs).
As for Amsoil, decent product but I doubt I could get it for under $4/qt as a regular promotion point. Heck Havoline can often be grabbed for as low as $2.change.
