Customer Ratings & Reviews

I like Amsoil because it really holds up under heat in these Harley twin cam air cool engines

Product is the best on the market for all of my motorcycles.

Great oil.

Haven't had issues yet. Been about 1700 miles

The Pinnacle of motor oil. It just don't get any better.0

I've been using this oil in my twin cam 88 for many years now and I absolutely love how my engine shifts smooth and just all around everything that an oil should be this oil is it and so much more

I've bought this oil and filter a second time now. I reviewed the first purchase also as positive. What really sold me was seeing an old Evo Harley at the Amsoil display at Full Throttle outside Sturgis a few years ago. The HD had been sitting idling when we arrived and was still idling when we left about an hour later. That was impressive. I made up my mind at that point to review Amsoil and purchase. So glad I did. My 2018 Chieftain always ran great but the Amsoil has made it better. Thank you for this great product.

This is the only oil i use in all my motorcycles. And has been for many years. Have never had a Motor or oil related problem. Their is no reason for me to ever change oils.

Great product run in all my bike

The best blood for my hawg! Fast delivery as always too. THANKS AMSOIL!!!

I have used your product in multiple high performance motorcycles, it is the only way I roll now. I've tried the competition, Mobile 1, Castrol, HD Screaming Eagle, K&N and Valvoline. There is no competition when it comes to heat protection, fluidity and duration. Thank you Amsoil.

After doing some research, I switched to full synthetic Amsoil 20w-50 for my 2015 Indian Thunderstroke 111. As I have doing more research I find that 15w-60 synthetic may be better. I may go with that my next oil change. But wish you guys would sell that weight oil, in gallon jugs though. Any chance on doing that in the near future? other than that, my 15 Vintage with 45,000 miles has never ran smoother, thank-you.

I been using this oils for my 1991 Harley Davidson,and my bike has 258 295 klm and the motor has never been touched yet !!! I put this oils in 3 holes,motor ,transmission and the primary,so I got nothing bad to say about AMSOIL!👍😎

Great motor oil been using it my Harley’s for about 10 years

Amsoil is the best oil I have used. Doesn't break down and keeps engine clean.

Since I started using this oil with the AMSOIL Black Oil Filter years ago I have been pleased with the results. Not just in my Indians but my previous metric bikes.

Just changing my bikes over to amsoil all is working well . the 60wt is being used in my 1974 harley fl , the 15 ultra also doing good on 20-50 when it's time I have 1 more to go

Fast shipping and excellent quality

The only thing that I thought would make Amsoil better was gallon jug packaging. They did it!! Awesome product now in perfect packaging

I love this product, been using it in my new bike. But now can’t seem to get an oil filter to do my next oil change. Not sure if I’ll stay with this or not.
