Use it in everything, vehicles, chainsaw, dozer, basically everything, small engines up to big ones, gas and diesel both. It does offer extra lube while helping clean carbon. I also believe it helps prolong gasoline, kind of like stable.
I owned a 254 jinma and it ran great, well worth the $$$ and was still running hard when I let it go(900+hrs). Infact I kick myself for selling it, and now I'm looking to buy another.
Fla45Fan: Who is the dealer that you speak of in NY? I tried the name you gave and they wrote back saying they've never sold TYM nor do they even know what they are. They said they only sel MF's. I live up in the adirondacks and am interested in the TYM models T233 through T433, Thanks for any...
