Wanted to change diff oil before winter riding. What does Suzuki recomend and what has given the best service?

 

I've changed the diff oil on my eiger 3 time now (once a year) I have always put mobil 1 synthetic gear oil in (75w90 I think) never had a problem. If the Vinson has the same diffs 1 quart will do it. I think I have about 2000 miles now. It has worked for me.

 

yeah i use Amsoil 75W-90 in my diff....oh...your gonna need a flexible funnel or a squirt bottle to get it in there...i found it to be a PITA
