Bob,
I agree with you regarding the Accusump, but to each his own.
People swear by
synthetic oil for street cars, but I've gotten 200K miles out of two different vehicles using any
oil (dealer
oil, Jiffy Lube's finest, etc) and filter. That's with oil change intervals of 5K to 6K miles against the factory recommendation of 7.5k miles.
My wife's MBZ uses Mobil 1
synthetic, because that's what the factory recommends. 11K to 13K oil change intervals...seems crazy.
