I guess I'm using the wrong stuff in my cars. The label on my Mobil One reads "MOTOR OIL" . The cheap Costal I use for the lawn mower also states "MOTOR OIL" I guess they are all wrong because off hand I don't remember any btands that state engine oil. I've been wrong before so please state a brand that states Engine Oil and I will switch tomorrow. 1@xxxxxxxxxxxxx www.BillAllen.net
