That would most definately be wrong... 150 hrs? you mean 15, that would sound better. If I were you I would go for one of those auto filters that fit your quad and stick with yamalube, its good stuff, and its what the company runs and so on, so you can be sure it will be safe, besides, why put something in thats cheaper and might not be as good.. On top of it, I heard that if you use synethic your clutch might slip. Someone correct me if thats not true. Since synethic is such a good lubricant.

hey mike read the link i posted in this thread it has alot of info on oil and what type to use

 

Ya I just did, pretty good info. I stand correct on my idea that the clutch might slip with synethic. I still like to play it safe and go with yamalube. Personally I would rather sacrifice the minimal lose in power due to the oil then to have to worry about problems internally in the engine, you know what I mean.?
