who runs these?? i was just wondering everyones info on these, which 1 would be better over the other for a raptor. also how many folks out there run synthetic? thanks!

 

I use castrol GTX 20w50 and have never had aproblem with it, and it costs half of the other stuff. Of course I change my oil every 2 rides but thats about 150 miles. I also change the filter every other oil change(Bosch 3300)

 

the royal purpal maxcycle is real good, probally much better then any you listed

 

may i ask why that is...?

 

I run amsol synthetic motorcycle oil in my Wolverine and Spectro synthetic blend at 36:1 in my Quadzilla. but 4 stroke Amsol Synthetic all the way. I run their differential oil too for my shaft drives. If you run synthetic dont forget that you cant run synthetic when you do motor work which requires you to do a new breakin (like new piston or bore). You have to run full dynosoar soup for that.

 

it is a full synthetic oil but its susposed to not harm the clutch either. i just found a write up about it on atv connection Click click on the link it should bring you right to it, that will probally tell you about it way better then i can

 

I run Maxima 10W40 and haven't had a problem with it. Though I've been thinking about switching over, but I haven't heard a good argument yet to convince me to run something else. I used to run GN4, but thought Maxima might keep the engine cooler.

 

Yamalube........ 5W30 Winter & 10W30 Summer. For Hot Summer and racing I would run 20W40

Great protection and cost about same as everything else.
