This question was asked in July 2002. My answer was free Redline 10W40 delivered by Anna Kournikova in a wet T shirt. I'd still like free oil and Anna would still be a fine delivery mechanism. After reading this board for 18 months, I've accepted the logic that my bikes and cars don't need the same oil. 10w30 for the cars is OK. I guess Anna will have to make two trips to my garage.
