standard transmission oil

Thanks for the chart Dallas. Your right they are very close, so if these transmissions have an actual oil pump my 40 wgt should be good??


BW , you absolutly right on the HD thing. I have owned Harleys for years now and have always run a 50 wgt although usually a 20/50 wgt. The problem is I've only been able to find it in litre containers, and it's not cheap buying in such small containers. I have never tried a farm supply store. They usually keep some unusual supplies , although I did get their last 2 pails of 40 wgt. They don't seem to keep a large quanity of that either anymore.

I have heard rave reviews before concerning synthetic in EVERY application.  The temp of your trans and dirfferential will go down significantly after you switch.  That should help with wear right there.  The shifting is supposed to become easier.  Syn is a BETTER lube than Dino grease so as well as the temp advantage the trans will last longer because of less wear.  THE BIG REASON is that the stuff will put MPG in your pocket and that is not a hunch.  I collected all the data long ago and I came down firmly in the syn corner but expense is a factor that cannot be overlooked but that is just for the first load cause it lasts so much longer it actually may cost less in the long run.

The 2 cycle oil used for the engine is difficult to come by and is getting more expensive.  The ash content that is admissable in 4 strokes is nothing that should harm a trans.  I note that the 4 stroke guys are not running 2 stroke oil so it must not be a superior lubricant to 4 cycle stuff.  In 20 degree weather 40 weight oil is just a little thinner than TAR.

YMMV,
