Castrol 06412 Power RS 10W-50 4-Stroke Motorcycle Oil - 1 Quart Bottle, (Pack of 6)

I was running 20w50 in summer but started getting horrible gas mileage in the "winter" when temps dipped down into the 40s (brr) at night. Also, I noticed starts took an extra crank. I switched to this stuff my engine starts up much better. Also my fuel economy improved. I feel better running this 10w50 all year round since temps out here get into 110°F easily. Pay the extra couple bucks and get this stuff. - Customer Reviews
