The Clymeranual doesn't state it either. It says, use only a high quality detergent motor oil with an API classification of SE or SF.
About 90 % of the motor oils (cheap or expensive) you will find at any auto parts store, grocery story or kool aid stand will meet these API classification. You do not need to spend a lot of money on tranny oil. The key is change it frequently.
MotorGeek, there is no doubt in my mind or questioning what you say, cause I KNOW that you are like the Wikipedia of our qr's and other quads too. Your kind of like my grandpa, when he talks, everybody shuts up and listens cause we have respect. We now know that it is important to change it very often and that most oils meet the API standards,.... Knowing this, what do you yourself use?
What ever oil is on sale that week.
