Guys, I just want to know the difference between the SVG 75w-90 vs the SVO 75w-140 Amsoil. I found out that my dealer carries Amsoil, but they only have the 75w-90 and not the 75w-140. They told me that I didn't need the 75w-140 and that I could use the 75w-90 on the transmission. Please help me out guys. I really trust your word better than theirs.

 

I have been using SVG 75/90 in my 03 Ultra Classic since it was new, the "Harley Clunk" when shifting is almost gone. As an AMSOIL Direct Jobber I can tell you that that is what AMSOIL recommends also. SVO 75/140 is the Alternate. here is a link to the AMSOIL Harley recommendation Chart https://www.amsoil.com/products/stre...oil_chart.aspx

 

They just came out with a 75w110.......check the amsoil website. It will give you a little more heat protection without sacrificing efficiency. I do think it is a good alternative.

 

My 92 Ultra Classic has a whine in 3rd and 4th gear. It had the HD Formula +, I switched to Moble 1, it was a little better then I went to Amsoil SVG 75W90 and saw a much lighter noise and better shift. I just ordered Amsoil'sSVO 75w-140 tonight to test it and see if it would reduce the nosie even more. Will post results in about two weeks.

 

Don't worry... You can still go to Redline SHockproof Heavy 75w250...like me

 

Wanted to try Redline since I had heard only good about it. Had to travel 120 miles to another town today stopped at about 6 different locations looking for Redline Shockproof heavey, no luck, so ordered the heavest recommended for Harley bikes by Amsoil.

 

A lot of my customers and myself all run the 75W90, it shifts smooth as hell and gets rid of the clunk. Also, pretty quiet, but quite honestly, I can't hear much over my exhaust..

 

thats what I'm running now I like it but want to try the SVO 75/140 to see if I can get the noise down a little more. If not I'll just turn the radio up when in 3rd and 4th gear
