Customer Ratings & Reviews

I have been using Signature 5w30 EAO17 filters since 2013. Very satisfied

I’ve been using Amsoil for quite some time. I’ve used it in my Harleys now in my Nissan Sentra. I can’t say enough good about this type of oil. Great job guys.

Amsoil is my go to oil...

No doubt, the best engine oil you can buy to protect your engine. I use it on many different vehicles. I never worry about extended drains.

These are superior oils! I wouldn’t use anything else.

I use it in all my cars and Pwc

Used in 2004 Ford Expedition..wife runs about 7k a year...once a year oil changes...210k on truck...no oil burning, gas mileage is same as new

This is my new favorite winter oil for my Tacoma and rav4. Better cold starts than 5w30

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.
