I need to drain my gearcase oil and they sold me on some Polaris gearcase oil at $15 a quart. I still have the receipt. It's gear oil right? Some cheap stuff at walmart should work fine on a $1500 quad... what do you guys buy? Does anyone know how much a 400 2stroke uses for gearcase oil? I dont have a manual. Any weight specific stuff I should get.

 

Are you talking about the transmission or the differential, what machine is it and what year?

 

its a 1994 400L and need the gearcase oil
