Customer Ratings & Reviews

6k miles in one year; no oil consumption; consistent fuel economy.

shifts smoother and run cooler.

I like the fact that I can put my vehicle in the search tab and find the oil that is needed and also the amount that the vehicle takes !

I have 4 motorcycles, they all get the metric motorcycle oil. Smooth shifting and lower temperature overall.

I have been using this oil in all my bikes and never had any bad results . I am 74 years old and that said adds up to some serious amount of miles . A little costly but you get what you pay for , great product .

Okay you wanted it so here it is. How can anybody without lab equipment really give a realistic review about just how good an oil is? I have always used top-notch oil. I tried this oil because of the tests that I saw on YouTube. I have reason to believe that there isn't anything better for my motorcycle than this. I will continue to buy it because of the testimony of other people who have done extensive tests against other oils. It seems to work very well in my engine but I can't tell a difference in any way because I always have used very expensive oils.

After trying MANY different oil brands (Motul 300V, Valvoline, Pennzoil, Mobil 1, etc. and all full synthetic) in my 2019 Yamaha R6 I have found that Amsoil Full Synthetic oil is the best for the motorcycle and will never use any other oils in my R6 and my other motorcycles.

Good stuff I’ve tried royal purple and this brand of oil. Yes it’s a lot more expensive but it shifts better and I have never heard anything bad about ams oil

I trust Amsoil products. I have seen inside of engines that have used Amsoil and I am convinced their oil and filters work at a very high level to prevent wear under extreme conditions.

HAVE BEEN USING YOUR OIL IN MY BIKE FOR OVER A YEAR NOW AND IT PERFORMS GREAT IN THE HEAT(105-120 IN THE DAY) AND IN THE WHAT WE CALL COLD (40) OIL DOES ALL IT IS ADVERTISED TO DO LONGER LASTING ..BETTER SHIFTING... A MOST HAVE FOR BIKE RIDERS ...WILL KEEP ON USING THESE OILS IN MY BIKE AND FUTURE BIKES...

This particular oil I purchased was for a customer who owns a CAN AM. He was told by his dealer that a Blended oil was recommended, a mix of conventional and synthetic. He was a heavy duty mechanic. I challenged him with the statement: there is no such thing! I then emailed an Amsoil Tech who concurred. He switched his oil and cant get over the significant difference in the engines operation.

Extra insurance to keep my 35 year ond bike running and shifting as good as it still looks!

Great oil helps my metric cruizer shifting easy!

Change my oil on my 2020 r6 every 1k miles and I am not disappointed with the performance Amsoil Full Synthetic 10w-40. As far as ordering, always have product in stock, shipping is fast/reliable and customer service is top notch!

I have been running the Amsoil in my 2005 Suzuki vstrom Since new over 108,000 miles still running strong. I’ve also ran it and all my dirt bikes and quads. My wife quad lost the oil plug she rode the quad for about 5 miles in a quit towed it back to camp put a new plug-in filled it back up with Amsoil started up and ran fine the rest of our trip and is still running fine

Amsoil allows me to ride my Honda Goldwing all season, without having to worry about changing my oil so often, and I think it shifts better also.

Easy to use

I bought two 3.78 quarts of this oil for both my r6s but after putting my clutch plates back into bike I put oil plug back in. I filled the bike up with most of one jug I started the bike she ran awesome but I noticed it was leaking at the plug. So buddy got me a clean bucket to drain oil into it to be reused but there was a hole in the bucket lost all the oil so got to rethread oil pan hole now

When I first found a 1974 Honda Elsinore a few years ago it was confusing trying to figure out what modern oil would do the trick for a 45 year old bike. I contacted Amsoil and they were very helpful pointing me in the right direction. Metric was the product I needed.

I immediately noticed the transmission shifts smoother on my Honda Rebel 500.
