I have been using AMSOIL for the last 4 years. It works for me.
AMSOIL has the JASO-MA Rating. Which grade do you use 20W50 or 10W40?
Being further north they suggest we use 10W40 up here, wehaveplus sinceour Victorys come withOil Coolers installed on them.
I have used both. Depends on the time of the year, andwhere I am going.
Iuse 20W50 on the longer trips. I have run intotemps in excess of 110 degress (up to 117 degrees) on every road trip so I like the heavier oil.
I also extend my oil change intervals to around 5000 miles on the longer trips.
The trip I took in 2008 I had to change the oil 3 times in 11 days. Gets expensive!
