wkohn said:I sell Amsoil and this is what I have been using in my bike.
MCV 20W-50 (engine and primary)
SVG 75W-90 (transmission) Might go to 75W-140 this summer
AME 15W-40 (engine)
MCV 20W-50 (primary)
SVG 75W-90 (transmission)
Mobil 1 works better that the other stuff at the stealer. I case you are low and need to add while out of town.
I used the new 20W50 Amsoil formula in my engine last season with Redline in the Trans. This season I'm going to try all Redline (20W50, MTL & Shockproof Heavy) because I think Redline makes a fantastic product. Prior to making this decision, I was also curious about using either Mobil or Amsoil's SVG 75W140 in my trans.
The following is the response I got back from Mobile regarding the use of their 75W140 gear oil in the Harley transmission: "The Mobil1 75W140 should not be used as this is too viscous of a fluid and will not allow proper protection, performance and shifting chracteristics."
