Oil Viscosity not listed.

I have fully Synthetic 5W50 JSO-MA but my ATV doesn't really say what oil weight to use. It more or less just show you a range; 0W30, 10W30, 10W40, 15W40, 20W40 OR 20W and JSO-MA.

I'm in NY but my ATV is mostly garage kept and stays above 60f. Should I just get different weight or stay with 5W50?

I don't see 5w-50 listed on there at all. I think I'd personally run a 15w-40 given your comments about garage (starting) temperatures, and the fact that over 110F in NY is an absolute rarity.

I agree, unless you use it in the winter?

I ran Rotella T in my Grizzly years ago and it liked it. I ran Amsoil originally but it liked it too much if you know what I mean.

I ride just as much in the winter as I do in the summer.

Then follow your manual and run the right type/weight of oil for the conditions you ride in.

It's been 10 yrs since I owned mine but I believe I ran a 5W-40 or a 0W-40, I forget? 0W-40 Mobil Euro in my Vector for years without issue.

I'd try a 5W-40 like Rotella T6 and see if that works for you....

LOTS of people run it in their motorcycles! (that make big HP)

Do you do cold starts in winter outdoors? If not, looks like the Manual recommends 10W-30 and up to 20W-50.

Well it's in the garage if I leave from my house. If we trailer somewhere it would most likely be outside.

Amsoil 5w50 atv/utv? It will be good for winter and summer use. But having that wide of a viscosity range, I'd be opting for short intervals on your changes. Run a uoa on it during the warmer months and see what it shears down to.

I would run 5W-40 if it is available. But not MA only. MA2 dis much better than the old MA category (which became MA1). If it only says MA, it is probably old and still slips. There is a huge difference.

Exactly why you should run the type/weight of oil for the conditions/temps you ride in. 5W-40 or 0W-40 like has already been recommended.
