great points Don!.......I honestly didn't think of that......but my whole question was referring to the good ol' boy rat named Cuz that is retired, got the coins to buy a Merc., buys it, ain't got no puter to have great folks like you to help him out, and goes and runs some off the wall oil and runs premium gas in his 2011 250xs because his jacklegged mechanic, named Bubba, said it'd "make her scoot."

those folks are the ones I was referring to..........not the freakishly detailed computer havin', BBC addicted morons like yours truly
