Hi Dave
Hope this finds you well.
Well, I have gone quite a while with no questions but I have a new one.
We bought my wife a Harley, an used 09 ultra with the 96" motor, all stock. It has been on Amsoil for all 13,000 miles.
I am definitely putting Red Line in the Motor, Primary & Trans.
My question is, I was just reading a new article published by Amsoil on oil comparisons. Of course they never compare themselves to Red Line. Does Red Line have anything new that shows basically all the points that Amsoil tests for?
You probably have seen it but I have attached the Amsoil white paper.
Thanks
Bill

Bill,
Yes all is well here...
I have seen their motorcycle oil test, thanks for forwarding it.
In your new Harley I would recommend the 20W50 Motorcycle oil, it has a VI of 152 and is completely sheer stable 0% loss, the HTHS viscosity is 6.1cP. The zinc level in our Motorcycle Oil is 2500 ppm, the phosphorus and sulphur level is more important for flat tappet anti-wear protection, 2100ppm phosphorus. As noted in the test, the ZDDP level doesn't reflect on the four ball wear test results. I don't have those results for our Motorcycle Oils as we generally don't perform that procedure, it's results can be misleading, good performance doesn't necessarily translate into a better performing oil. We performed a comparison between our motor oils and the Amsoil, I have attached that procedure, it shows how the additive they use for results degrades with use, our products improve with use. The volatility is 5%, the TBN is 8. The price per ounce is $0.247 We classify our Motorcycle Oils as MB due to it's moly content though they are not too slippery for wet clutch operation.
I don't have the D-5182, D-4742, D-892 or D-1748 results but have no doubt it would pass.
In your Harley's primary I would recommend the V-Twin Primary Case Oil also packaged as MTL and the V-Twin Transmission oil also packaged as ShockProof Heavy.

Hi Dave
Thanks very much for the quick reply. Just a final question on the Red Line. I run the 20-60 MC Oil rather that the 20-50 even though the MC’s are 2006, 2009 and the reason I do is because I ride in such hot weather. Living here in Reno and riding in summer temps of 95+ a lot of the time. Not unusual to see temps of 105. Should I stick with the 20-60?
Thanks
Bill

Bill,
The 20W60HD would be a good option for your Harleys though not necessary. The 20W60HD is primarily used in engines running very high oil temperatures where additional viscosity is desired or where internal clearances are looser and the rider wishes to reduce the noise. The 20W50 and all the oils will certainly handle temperatures, the 20W60 would operate a little warmer but would provide additional viscosity, additional oil pressure and noise attenuation for those extremes.
