I've used this over 2 years now never had issues with my clutch slipping

Been a long time Amsoil user and recently purchased a used '08 Kawasaki KLR. Don't trust the motor to any other oil.

I had occasional clutch disengagement issues (sticking) on a vintage dirt bike when using my Amsoil diesel 10W-40. I suspected this may be oil related, so I changed to Amsoil Dirt 10W-40 and the problem never occurred again.

Made a trip to the desert, change the oil on the motorcycles and quads but apparently I forgot to tighten the drain plug on the wife’s quad. We’re riding all day on the way home the plug came out of the quad, and the wife rode approximately 5 miles in the quad stop Towed it back to camp put in another drain plug filled it with a oil and the quad ran fine. Didn’t miss a beat that’s why I swear by Amsoil.

First oil change on cycle. Being a preferred customer saved a bunch. Can't beat the quality of Amsoil for any application, keeps cycle running smooth and shifts with ease

Great product and very fast delivery

The ONLY and Best IMO, Oil I use to keep my 450 running in optimal condition. Thank you Amsoil for making great products we can trust.

Was having problems burning up clutches on my pit bike Crf110 now that im using amsoil no more issues

Superb oil, run this in all my dirtbikes, great clutch feel and smooth shifting. Would recommend this product to anyone else.

Running AMSOIL motorcycle oils for about 20 years has given me peace of mind to never worry about engine protection, running one year drain intervals, clutch problems, or any other oil-related issue.

Have been using Amsoil in this bike since purchase. Where other bikes have blown up this bike has always been up for a weekend on the track. Thanks Amsoil

I swear by the Amsoil went to the desert, change the oil in all my vehicles while out, riding in the desert. The drain plug fell out of the wife quad she drove it for over 5 miles before It quit. We towed it back to camp put more Amsoil in it and it ran fine the rest of the trip. We never had a problem with it the whole time we had the quad for another five years.

My 2004 KTM 950 Adventure LC8 just loves this oil. Clutch, shifting, engine--all behave perfectly.

I used this on my 2020 Kawasaki klx230 dual sport motorcycle I do ride alot of off road and street prob more street and for a dual sport or dirt bike this oil is so good shifts better smoother bike runs cooler just super happy with it all the agy around

Best product out there

Excellent oil that provides long engine life under the most extreme desert racing and long-distance dual sport backcountry remote expeditions! Amsoil engineering, product development, and customer service is the best in the industry based on my 47 years of riding and racing. Starting with 125cc bikes in the 70's running 100:1 Amsoil premix, I've gone through many, many engine rebuilds to include high-output, high-rpm modern 4-strokes over the years and have never found any component failures that were attributable to quality of the lubricate. I just started buying from Amsoil direct after my long-time dealer buddy retired and moved away. What outstanding customer service I had and easy to use website. Keep up the great work guys! I'll be back soon!
