I have owned Seadoos for over 20 yrs. I change my oil once every season at the beginning of the season and I ONLY use Seadoo brand recommended oil. I know its costly but I have NEVER had a ski problem. My friends and family members have used cheaper oils and had problems down the road.

20% of 215 = 0.20 * 215 = 4320% off of 215 = 215 - 20% of 215 = 215 - 43 = 172
(215 x 215 x 215) = 9,938,375
