john3_16 said:O.k....It seems fine to run 2 stroke premix gas into a 4 stroke motor...But, how long would a 4 stroke motor last if you dumped the oil used to lube the engine and just ran 2 stroke premix gasoline for it's source of oil ?
BadgerMan said:As an aside, I once had a lawnmower that I had bent the crankshaft on (hit an exposed root). As a result, it vibrated and started using oil pretty badly. I was planning to buy a new one but thought I would run the old one until it quit. I put every type and weight of leftover and used oil in that thing in an attempt to kill it, including atf and fork oil. It never did quit so I gave up and got a new mower.

MOTOX888 said:Yea, only premix will NOT work in a fourstroke. The gas/oil muxture enters the bottom end first and then works its way up in a 2 stroke. There is no way for the lube to get to the bottom end of a fourstroke without transfer ports.
