'Superior Wet Clutch Protection'
« on: April 13, 2008, 10:54:23 PM »
This is the claim on the front label of the 20-50 Valvoline 4 stroke motorcycle oil I just bought. I have read numerous posts concerning different oils for the primary drive. One of them, by Vince, was quite adamant about using 20-50. Wouldn't it be prudent to adhere, as closely as possible, to the factory specified requirement, IE, 15-40? I had a choice between the Valvoline 10-40 and the 20-50. Are there any thoughts on this, based on 'scientific' studies? Rotella was the only 15-40 I could find. It is, course, not specifically for motorcycle use. Cheers!

I doubt if there would be any difference between brand names.  Most of the oil suggestions are just guesses anyway.  If you really want to be safe, try some Top 1 oil that our host sells, its the best of all.

I have read that using type F ATF fluid is good... can anyone concur?

That is one of the two options listed in the Snidal manual. I picked up a quart the other day to use when I open up the Primary to install the heavy duty clutch springs, but I haven't had the chance to do the work yet.

I switched to type F ATF fluid last year. I have put a minimal amount of miles on it becuase of other problems/rebuild but it seemed to work fine so far.

     In the primary you can use just about anything wet and slimey. It is merely  convenient to us the same oil as in your engine. Keep in mind that ATF is primarily a hydraulic fluid, not a lubricant. It will work, but regular oil is better in the long run. !0W40, 15W40, 20W40 use a base 20w viscosity with an additive package to give it the flow rate of the lower # at 0 degrees Centigrade and the flow rate of the higher # at 100 degrees. 20W50 uses a base 30W plus the additive package.

I tried ATF and at highway speeds it weeped out of the breather hole and down the case. Not real bad but messy.  I went back to 10w-40 and no more problem.  Just my 2 cents.
