Hey guys n gals, I'm not trying to start a debate or argue what's best........... just thought it would be interesting to know what everyone uses in their bike (eng oil, tranny, primary). For me it's Mobil 1 Syn for Vtwin 20/50 in all 3 holes.

I've been using Castrol 20/50 in the engine for years, I use the HD primary and trans oils. Got lots of miles and years and the bike still runs great.

i am a Mobil 1 guy... have been for a while. no issues.

Gas

Sorry couldn't resist. I use chevron with techron. Keeps the injectors clean. As far as oil transmission fluid, fuel additives. I use whatever my HD dealer recommends. Probably cost to much.

I must be missing something, how does engine oil keep your injectors clean?

Just mainline it into the fuel line.

Just Kidding, CHEVRON 91 WITH TECHRON ( thats gas by the way) keeps the injectors clean. LOL I wasn't clear if he was asking about gas, oil or tranny fluid so I gave and answer for all three.

As for gas, I've found that Mobil premium seems to burn the best in my bike. I get 1or 2 more miles to the gallon and slightly better performance. Why i don't know...

Castrol 20/50 racing oil........HD tranny fluid n fork oil......as for gas never enough! nothin but premium....wherever i have to get it. Sunoco seems to run best.........someday jet fuel if i dont quit buildin on it

just buy kerosene instead of jet fuel, same stuff. you might find a little hard to light though, I would recommend a good race fuel of 112 or higher octane rating
