Most people think all oils are at least "safe" to use in thier engines. scroll down and read about some of the oils that don't meet specs for any engine in the last 50+ years. These oils are sold daily... I doubt anyone here uses them, but don't be tempted when you or the wife is a little below the full mark or just buying a little time till the next oil change...
