Heck, I am impressed he was riding that old bike! But, they are still out there and on the road. If he was running Mobile syn. on a machine that old, that is a recommendation. There is a vendor that runs ads for special oils for really old machines in "Classic Motorcycle" I think. None detergent as I recall. I think even in the really old bikes, such as the 30's era Indian, as long as you've good seals synthetic is a-okay. And even if you don't have good seals just watch your oil level, as I think probably most/all those old bikes will leak or weep some. Although, and anyone can correct me here, there may have been "total loss" oil systems still around in the thirties, in which case loss of oil wouldn't be a concern I'd think.I camped with a fellow a few years ago that was riding an old 1930-something Indian Chief. He was doing a check of everything one morning when I ask him what kind of oil he ran in such an old bike. he just smiled and said Mobil 1 syn. He said it cut down the wear on critical parts by 50%. I was impressed.
