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

Just can't say enough about amsoil incredible strength durability its amazing the oil takes so long before starts to break down also oil changing intervals are a lot less amazing oil worth every penny I only buy amsoil I am 34 have car with a lot of horsepower and one with barely any they only drink synthetic amsoils best oil I also just bought 3 dirtbikes there all getting amsoil you can run the stuff in anything BEST COMPANY FOR Oil Hey amsoil if you guys get any amsoil gear I'd love to get something like a hat or anything to advertise my number 1 oil company I have 2 stickers on my new dirtbikes that are amsoil from ordering oil lol but can't find anything cool that's amsoil to show my dirtbikes off I looked online I want the brag rights for my oil lol!!! 10 star ⭐ company for real no lie.

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!

Best oil out here

I change oil every time we ride so don’t know if it make much difference

awesome product

I've been running AMSOIL in my XR400R for 25 years and just checked the compression, 11 PSI off factory spec. It runs in the Arizona desert and engine temp is normally high (220), its an air-cooled bike and heat dissipation is everything.. I think AMSOIL adds Unicorn pee or something magic, that's the only way this is possible...

Bought a 2011 Husqvarna sms630 recently and thought I’d need a new cam chain tensioner until I tried using this oil For the first time as I’ve always had good luck with Amsoil products. This oil made my engine run super quiet and so smooth! And even after breaking in a new clutch this oil turned black and was still super clingy and slick feeling. Highly recommend this for your dirt bike!!

Great dirt bike oil

Dumping this oil in our race bikes. Seems great so far

Been using this oil in our race bike. Change it every 5 hrs , working great so far.

Have never had a bearing failure are a clutch failure using Amsoil. I have both 2 stroke and 4 stroke bikes. I recommend it to other people that I race with and service bikes for.
