When I first purchased this quad I asked the service guy what oil is in it, he said Kawachem 20-50w, I thought 10-40w would be the weight but he said all the bikes he services get the Kawachem 20-50w, Iam out here in the Desert in Arizona so maybe thats why 20-50w is used, I dont know. I was gonna get some Spectro but the service guy said you dont want to be switching oil weight or brands if you have been using the same type since you owned it, I still have 3 years on warranty and don't want to void. Is 20-50w to high or what? Thanks

 

you can switch oil brand they are all basicly the same..yeah i use spectro 10w40 all year around and it work fine..being where you are maybe that why he uses 20-50w..but i dont know...it sayz to use 10w40 anyways..i have never had a problem with spectro... it has always been one of my number 1 choices...
