I bought a case of this oil for my yfz quad, Bel-Ray Thumper 4-Stroke Racing Motor Oil.

Thumper 4-Stroke racing motor oil is a premium multi-grade synthetic blend motor oil engineered for single cylinder multi valve 4-stroke racing engines. Will running it in the SV650 twin cylinder hert the motor?

Here is a link to the oil,

The oil that i was using in the SV was, Golden Spectro 4-Semi Synthetic(which i ran in my dirt bikes and quads). I want to change to bel-ray, becuase i like the performance that it has with my quad, and i think its a better oil/brand. I have all this thumper 4-stroke oil laying around, and i just want to know if it is safe too use to save a little money, so i dont have to buy the oil specifically made for superbikes that bel-ray makes. Any of you use thumper 4?

does it have an API classification of SF/SG or SH/SJ, or JASO classification of MA ?

is it a viscosity of 10w-30, 10w-40, 10w-50, 15w-40, 15w-50 or 20w-50 ?

If it's 10-40,and not energy saving.

On the back it say's, SAE 20W-50 API SG. I have only 2 litters of 10w-40, and alot of 20w-50.


Also is it fine to change to new oil and not change the oil filter?
