Customer Ratings & Reviews

great oil. i use it in my 2001 ford truck.

Use this in my 19 Toyota Tacoma. Runs quiet and smooth. Feel good knowing the protection of AMSOil.

This oil is fantastic. My 2.5 Turbo runs smoother and quieter and the protection is second to none. After 8,000 miles this oil is just like new in the crankcase. Yet I'm not surprised... my prior auto ran 425,000 miles without a single engine repair! I will always recommend Signature Series Amsoil..

Started out using amsoil in my 2015 chevy 2500HD Diesel...it alwas drained as clean as when i put it in....101,000miles so far and mileage is still 29mpg Highway.....Just took delivery of a 2023 ACADIA SLT 3.6L in May 2023...at 1600 miles i drained the oil that the dealer put it....it was BLACK....who knows wht oil these dealers put in your new vehicle....at 2000 miles now the oil is as clean as i just poured it in.....am getting 30.5 MPG HIGHWAY...!!!!

This motor oil doesn't burn like the previous motor oil that I used (Mobil 1). It lasts the entire duration between oil changes without having to add additional oil. My car has 278,000 miles and I want it to last many more miles.

Been using this oil since 1995. Did some modifications on my 1998 Camaro and there was no noticeable wear. All the parts looked brand new. I use this in my hot rod and both of my other cars. Simply the BEST

My truck loves this. Runs smoothly and greatly reduced maintenance costs. Have over 8k on this oil and still looks good.

This is the best oil I’ve ever used,there will be no other oil that is going in my Heritage Softail!

This oil seems to be an elixir for my 115k mile F150 workhorse... she's running smoother than ever (I've run Mobil1 syn since new, until now). Highly recommend for your car or truck too!

very pleased with this oil ffelt the difference on my 2019 ram runs cooler and can feel the engine is quiter now after using this product

Amazing product, the advanced quality can be seen in the YouTube videos that compare Amsoil to other top oils, Amsoil way better after freezing, and heating. Now I want to buy transmission fluid for my cars and oil for 2nd car, and am frustrated I will not get the preferred customer discount for my first purchase.

This is my first time using the oil and filter but I will come back with a answer but one thing I noticed is that it is really quite

Good 👍

I drive a 2002 Honda insight. I have always used 0W20 signature series. My car now has 412,000, miles. I usually change the oil around 10,000 miles. It does not use any oil from oil change to oil change, I have never had to add oil. It is never low. And I push the motor hard because it's such a low horsepower motor. Must be darn good oil.

I have found that using this oil has reduced my oil consummation for my 2013 Chevy Avalanche with the 5.3 engine.

Excellent

I began using AMSOIL in the 70's and have never used anything other than AMSOIL in all vehicles owned since then, never having a lubrication problem. Drove my former 2000 Dodge Dakota 144,000 mi. pulling a travel trailer for about half the time. Again, never having a lube problem, never having to add oil between oil changes. I presently use the Signature Synthetic 5W-20 in my 2016 Jeep Cherokee always following the oil/filter change recommendations, 25,000 mi or one year, whichever comes first. Not doing as much driving now with only 59,000 miles on the Jeep, changing oil and filter once a year. Even if I was not saving money, which I am, I would still use AMSOIL for it's superior lubricating quality!

So far I have only put this in my Ventrac Tractor with 3 cyl Kubota gas engine. Only have 50 hours on so far. Will be putting it in my 2018 Chrysler 300 and my 2012 Jeep Wangler on the next oil changes.

I've been using Amsoil in my Boss302 Mustang for the past 10 years and it performs fabulously. I get it tested and told I don't need to change it yearly because it looks new. Great combination!

This is what you want to use in the Jeep 3.6L Pentastar engine. This oil will lubricate the upper valve train in this particular engine an help alleviate wear.
