    Dixon in VA

    I bought this oil due to the reviews and I am glad I did its a little expensive but seems t be a much better oil than I had been using much better clutch feel, I believe the engine runs cooler and is much quieter.

    Best oil i found in 30 yrs

    I have ridden maxima oils and motorex in my ktm but i must be honest i dont see the gains. People are almost religious about their oils and altho they are good they fade after 3 hrs and i can feel it shifting. They get hot and break down. I am no expert in the science of oils but iv ridden since January 1st 1983 so do the math. I currently own a gsxr750 i race in the open expert group and i love to just ring right out to 14grand litterally 150mph every lap. I bought this oil at a local dealer because they offered little else and i put it in my gsxr750. I have never had an oil feel that good that long and you could hear the noise reduction. The bike was just happy. Im on my last quart of motorex and im switching all my machines over. Period. Insane how good this oil was.

    only oil I wil run in my motor

    Had my TRX 450r re built in 2015, the mechanic said it was the cleanest top end he ever saw, asked what oil I used. That was after 4 seasons of part time harescramble racing and another 3 years of once a month riding.
