I use spare Mobil-1 synthetic in everything... tractor, generator, chipper/shredder, power washer. Everything except for my old kohler K321 flat tappet engine on my (about 40 year old) ford lgt 145 lawn and garden tractor. It gets my used BRAD PENN!!!!
(since pelican isn't doing so well on pics today, here's the link to my self gratuitous garden tractor pic!)
