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.

Use this product in two dirt bikes my son and I ride and race. Will use nothing else but Amsoil!

Great product that does everything they say. The only oil I run in my dirt bikes. I don't have to rebuild my engines as often due to the quality of Amsoil. Which saves me money in the long run.

We have use this oil in all of our race bikes and have never had a oil related failure. Both Vintage 2 strokes and our modern 450cc 4 strokes. We also use Amsoil in our team hauler.

Ive used amsoil since the 70s and I fill its the best product on the market. I mix it 83 to 1 with aviation fuel and its the best,no build of carbon at all!!!!!

I've used this for years in Harley's and saw the difference in dyno numbers first hand as a Master Technician. Now I'm racing dirt bikes again in the GNCC Series and see the difference in engine wear and clutch performance. I would buy this oil even if I were offered other oil for free!

I use AMSOIL in everything I own without even thinking about it.

Amsoil is the best and this oil is no exception

Smooth, crisp shifts on my '17 Husqvarna. Oil at changes is basically still clean. Just another great product.
