I have a 2001 Yamaha Wolverine, I bought it used and I never put oil in it yet. What would be a good oil for me. Name brand and type.

 

Amsoil

 

10w-40?

 

10w-40 will b good for winter then 20-40 in summer or 20w-50 if u r running synthetic

 

Why should I switch for the different seasons?

 

I run amsoil 0w 40 in the winter because its a lighter oil for the colder temperatures.. In the summer run 20w 40 because the wolverine is an air cooled engine and will run much hotter, so a heavier oil is needed forsure.

 

not all oils are the same dont use the stuff you put in your car check this link out for some info on what to look for and what to stay away from.
