Customer Ratings & Reviews

I have always had great response to my ordering and the product without question the best you can buy.

I use an Amsoil engine flush and I put the signature for first and after 2000 miles I notice that the engine was extremely quite, amazing. With 180k miles it is running like new.

The shipping is fast and easy. No an engineer on oil, but I trust the great reviews. Hopefully it protects as advertised

Been keeping my high horsepower beast efficiently running safe for years. The best.

This has been in my fresh engine since the break-in oil was changed. Love it and I feel it has been the best oil I have used in any engine I have built!

Amsoil is pure liquid gold! High quality product with great communication during the shipping process!

I am extremely confident in running Amsoil in my vehicles. it has proven itself over the years and ranks very high on all the independent differing tests for oil. It does what it says it will do!

I love this oil. I've been using it in my 2010 370z, it's a daily and a track car. I was not expecting to feel such a difference when switching from Mobil 1 to this signature series. And my over all oil temperature stays below 200° before it would sit right around 240°

2021 Malibu ran better right afterwards. Idles better, accelerates better, sounds better. I knew with a turbocharger, I had to use the best. Used Valvoline synthetic before switching over. Will never use anything else again..

never received my free tool with order

Awesome products and was using Royal Purple until introduced to this and I now ask myself “Why Didn’t I Switch Then” but after switching and reading all the information comparison charts and end results I will never use anything else but AMSOIL. Great OILS !!!!!!

Had been using Pennzoil Ultra Platinum in my 2020 Tundra but after 4-5k miles on the oil I would start to hear a ticking noise which is common with these engines. I believe it’s the lifters. I switched to Amsoil oil and filter and have close to that mileage on the oil change, but this time no tick. Will continue to use Amsoil.

I use Amsoil filters in conjunction with Amsoil Signature Series 0w-20 motor oil in a Tundra, Sequoia and a Rav4. I have had my oil independently tested at intervals to 10k miles. The tests results convinced me this combo is nothing short of fantastic! Blackstone told me I could exceed 10k miles on an oil change interval......enough said!

Chevy Traverse 2019 engine oil change and filter. Well all I know is that it’s clean, feels like good quality and doesn’t spill. As far as the oil, I put 5.5 qts as it requires six I’m sure there’s oil still in the engine ajuste chillin in there so after filling, dipstick showed it was at the right level. The engine does make a different sound on start up. Possibly the oil difference. I will try one more time possibly at 8 k and not the 20k it recommends.

Big Fan of Amzoil because of the extended oil change. Back in the 1990's I was working in the racing industry (SCCA) on the weekends. What that meant was an average of 30,000 to 40,000 miles of driving and working 80 to 100 hours a week during the racing season. I never had an engine problem was running Amzoil. A mechanic that worked in the industry could not believe how nice the engine ran for the mileage on it and how good it looked inside. He started using it right away too.

Great Product, I put in my 2018 GMC Sierra 1500 Denali 6.2L 51k miles and the motor couldn't be happier plus me. The motor temp before ran a solid 210 degrees now 160-190 interstate travel. Average 4 hr drive at 85 mph it only heats up to 180-190 AMAZING without pulling a load. If driving around town or short interstate travel 75mph or below 160-170. The motor feels like it turns easier. I'm so pleased I'm getting ready to switch my backup vehicles oil to AMSOIL... I'D RECOMMEND TO CLOSE FRIENDS OR FAMILY WITHOUT A DOUBT... Thanks AMSOIL I wasn't paid or compensated for this review..

I’ve been a true believer in AmsOil since 1975. First used it in my new Kawasaki 900. I trusted it then as I do today. I just dropped the factory oil in my 23 F150 Coyote 5.0 could be the power of positive thinking but…I swear it runs noticeably quieter with this oil. As long as I can change oil it will be AmsOil for sure

I was won over with Amsoil in 2003 when I changed oil in my 2003 Harley Davidson that has a carburetor. You can learn more about a motor with a carburetor, the throttle, the click, the run, the function has more of a personal touch. The shift in the sound and the throttle response told me all I needed to know about Amsoil. I use in all five of my vehicles. Engines last longer and run at optimum levels.
