Yeah...as the OP, I blocked this guy on about his second post. I think this thread got away from it's original intent, and that is possibly my fault. It was not intended to decide which one to use, as I use both with confidence. I was just wondering why, NOACK values etc, a vehicle that uses no oil on M1, would use a half qt (negligible I know) on a different brand. In the end, it does not matter, I keep a close eye on everything, and it will never be an issue. Just an innate curiosity, a desire for information. I don't see any need to carry this any further, and I thank all for their input.
