Seems like you guys favor Yamalube so that's what it'll be. However, I seem to have misplaced the manual, so, how much do I need to buy? Thanks!

 

When changing the filter it takes about 2.75 quarts, without a filter change it was right around 2.25-2.5 quarts; as per my Clymer manual.

 

If you look near the dipstick on most quads it does have the oil capacity stamped into the cover. The warrior's says 2500ml. I don't know how that converts exactly, but it's very close to 2.5 quarts.

 

Man, you guys are fast! After I wiped the mud away it says 2500 cubic centimeters, (it's a 99), which is the same as 2500 ml, which converts to 2.64 qts. Thanks much! BTW, if you want an outstanding FREE convertion program, go to; http://www.joshmadison.com/software. Thanks again.
