Customer Ratings & Reviews

After using the manufacturer brand oil for the first two oil changes on my Honda CB 1000, I decided to switch to Amsoil. Immediate differences were smoother gear shifting, greater acceleration, and lower operating temperatures. I've tried many other brands of synthetic motorcycle oil and Amsoil is truly the best.

I run Amsoil in all my motorcycles. Started running Amsoil in my 2-strokes and now running this in my Triumph Tiger. Smooth shifting and excellent clutch performance.

Amsoil has always been my go to product and always will be

In just a few days I'll be putting up my dirtbike for the winter, and I want the factory oil out of it and replace it with the best lubricant and corrosion protection there is...it's as simple as that!

I have zero complaints about this oil. My order arrived fast and undamaged. Oil quality is as advertised and my bike keeps running smooth and shifting well. 10-10 will buy again.

Shipping was fast, packaging was perfect, and the product is amazing. The factory reccomend oil for my Ducati is no longer made, and this Amzoil product was the perfect replacement. 10/10 buying experience.

10w-40 Metric Bike oil is the bomb!!! I have been using it for years, with great results! Smooth shifts, no motor noise, and holds up to the heat!!! I use Amsoil in most everything in the dooryard it's a great product.

AMSOIL always ships fast. Their oil specifically made for motorcycles is superb. Biggest factor for me is made in the USA.

I absolutely love Amsoil products and have been using them for years. I’ve torn down my fair share of motors, this stuff is phenomenal especially in FL temps. Dump whatever else you’re running in your bike and pick this up. You will be glad you did.

I've used this oil in both my Aprillia Tuono and BMW R9T Pure. My bikes run cooler and the miles per gallon have increased slightly so far.

Just another great lubrication product from who I consider the industry leader in synthetic oil. Just changed the break in oil in my Royal Enfield Bear 650. All my bikes get Amsoil.

Used this oil exclusively in my 650 Burgman after I broke the engine in using regular oil, to allow for some break-in wear to seat the moving parts; since then I have used this oil exclusively and wear is no longer an issue after 50,000 kilometers.

When I ordered the metric motor oil I did so during a period when Amsoil was offering free delivery over $49. My order was well over $100 yet I was charged $12.99 +gst delivery. I emailed customer service, got a response, but no money returned as of yet. I hope this was just a glich because I really believe in the superiority of the oil.

Put this in my brand new bike and it feels way better then the yamalube that was in there stock. Immediately noticed clutch feel was way better and the engine sounds and performs better. It really works.

Super service livraison tres rapide a toute les commande que jais fait tres satisfait

I bought a new 2025 Honda Goldwing and have used Amsoil in my other motorcycles. I bought this 10W30 for the Goldwing as that is what the Shop Manual calls for, but in SJ grade. I did not realize this Amsoil product was SH grade, so I do not want to void any warranty for the Goldwing. I don't know what the difference is between SH & SJ in the 10W30, but the 10W40 has an SN grade, but the Goldwing doesn't recommend 10W40. I usually run 10W40 in my other motorcycles. So I will maybe use this 10W30 in my other motorcycle?

Good products works well. Shopping was great arrived fast

My Motorcycle performance is 100% better since I switch

changed the oil after about 50 miles much smoother shifting engine sounds quieter! with the VFR it has gear driven cams so lube is very important!

The bike doesn’t make that ticking sound on those really hot days.
