I race dirt bikes and have found this oil to stay cleaner than others after 10 hard racing hours.

I like the performance of this product in my YZ450F. Clutch feels great, motor runs smooth, and with the preferred customer pricing it's the same or better pricing than anything else.

The only oil I use in my bike.

I have this in 3 dirt bikes and so far I have no sticking clutch or anything. So I'm convinced it does it's job!

My regional dealer I get amsoil through is without a doubt the best freaking guy ever! Always resolves any issue I've had imeaditely

I started to run this oil on my adventure bikes. Needless to say that it does exactly what Amsoil says it does. Best clutch pull and feel, even after several slipper clutching maneuvers in difficult trails.

Put this oil in my CR 85. Clutch feel is better and gear changes are smoother.

Can't buy better

When switching from KTM factory recommended oil I noticed less engine noise and amsoil is not as expensive as the "orange oil". I've not done blackstone tests but I do believe the amsoil is working well for this 350xcf.

I currently own 4 dirt bikes and a quad and they all use Amsoil now. I've also rebuilt several bikes/quads that I've sold over the years. I've tested most of the major brands and Amsoil shifts so much better than most of the leading motorcycle specific brands! Amsoil is now my #1 with Max... being #2.

I use it in my 2003 Suzuki DRZ 250

Seems to work great and good clutch feel. Great price compared to dealer oil prices.

Use this in my 2017 Benelli TNT 600. Makes it run like a champ!!

I use this oil to keep 3 different enduros running strong.

Three dirt bikes running strong no clutch slippage great product

Amsoil has never let me down. Unlike other oils, Amsoil has never smelt burnt or looked broken down after any of our long desert races.

We use this on our race bike and when we service it still looks clean

When your race counts on superior engine performance there is none better than Amsoil to give you the confidence in your motor.

I switched from the traditional Amsoil Motorcycle oil to the Dirt bike specific formula when it came out a few years back. The claims about improved clutch feel were not exaggerated. Considerably better clutch feel in my old YZ250F. Smoother engagement and a better slip zone.

Love Amsoil products. Something I can count on always working even when racing is unpredictable.
