Customer Ratings & Reviews

Only use this oil in my 23 Shelby f150 truck. Best oil on the market for performance and reliability!

I grew up hearing my grandpa sing the praises of AMSOIL. Now it's my turn. We bought a 2016 RAV4 and started using AMSOIL. The result? This is the first car I've ever owned that doesn't burn or use oil between changes. The engine runs as well as the day we bought the car. What's more, I only change the oil every 15k miles instead of every 7500 miles. Win win.

I use this in all my Vehicles and families vehicles I say the price is high But what more a case of this oil are a new engine? I say the oil price is much cheaper. Buy it try it you'll see the difference in performance.

Can't buy I better all around product. Also run/ran the small engine Amsoil in my mower and dirt bikes

This oil might be more expensive to store brands but, you know where that money is going. I've had this oil tested after 5k intervals and the report came back saying the integrity was like new. I don't trust 10k change intervals, this oil I believe can stand up to that, as advertised. I've pulled the top end my engine and there's no varnishing. Just a clean engine!

New Amsoil user. I run it hard in a cammed-up 5.3 LS Sierra. My foot is never out of it and I’m not afraid to wind it. Time will tell, but zero problems so far. Fast service too.

Very good product

Amsoil got me through 22,000 miles before I could get my next oil change. I drive 2021 Toyota Tundra with no loss in oil when I check the dip stick. I would highly recommend it!

Engine seems to idle smoother with the Amsoil in my 2023 Raptor.

This is a great product that actually works. I read about people who write that this oil is too expensive. It's actually cheaper in the long run to use high quality oil than to use questionable quality oil that just barely meets the requirements. I use AMSOIL on all all three of my vehicles and my riding mower. One of my vehicles has over 304,000 miles, my next vehicle has 280,000 miles, and my third vehicle has 208,000 miles on it.

I have zero interest in trying another motor oil after trusting Amsoil in my vehicles since 2006. I only run 5K mile oil change intervals but they are hard miles on my Crosstrek with a 6 speed manual transmission. Zero oil consumption on an engine series that has a reputation for consuming oil.

This is the best oil on the market I only change my oil twice of years with this oil and I drive a lot of miles this oil has not fail me yet.

Costs more than conventional synthetic motor oil but the benefits of the higher tbn and base stocks give extra peace of mind for extending the oil interval.

A friend recommended Amsoil for use in my vehicles approximately 25 years ago and I am very satisfied with the results. Numerous oil samples taken from various cars and a pickup truck (mileage at sampling usually between 15k and 25k) convinces me that one gets what one pays for.

Great product. Highly recommended

I use AMS in my F150. First time using in my new to me Accord. Already getting 3mpg more commuting then previous oil. Its the only oil this car will get moving forward, plus i have piece of mind and changing every 10K instead of 5K

I see positive results now that I use Amsoil Synthetic 5w-30.

I've been using this oil in all of my vehicles past and present. My present truck has 149,000 km on it now but past vehicles have had 450k, 600k, and 675k before selling them. All used synthetic oil and amsoil filters.

Fast delivery , great product, buy with confidence
