Customer Ratings & Reviews

Awesome oil! Works well in my Honda Pilot. Saves me money and low miles = one change a year. If you gonna do it…do it right!

Great oil, I trust it

Only oil that I have found that helps with gas mileage.

This is the best oil out there!!! My truck runs smoother and much quieter also!!

Perfect OEM replacement

Switched to this in my 14 Outback which used 0w20 and burned a quart every 2000 miles since new. I was running 15w40 but mpg suffered and with the rising price of fuel, went with a zero weight oil. No more burning and better mpg

I have been using Amsoil since 1975 - never had any problems with any of my vehicles.

Amsoil was highly recommended by a good friend and mechanic. I now use it in my truck car and motor cycle.

Love Amsoil Products, they provide nothing but the best for your engine. No one I trust better after reading their reviews and most impressed by the independent testing they do on all their products. The Signature Series is probably their most tested and proven products, rest assured you are use the best the industry has to offer!

Helps prevent buildup on intake valves in Cadillac SRX. Nice quiet engines in our 5 Cadillacs 1959-2016, 95 Towncar and 2003 Silverado.

Been using this oil in my ‘18 Chevy Malibu since 15k miles and the car now has over 95k and the engine still runs like new. Definitely cheap and worthwhile insurance for anyone looking to maintain their engine for a long time.

When I bought My 2011 300 3.6 Penstar I immediately switched to Amsoil now with 110k miles she runs like new. I swapped my rocker arms and lifters because of a slight ticking not associated with the fuel injectors, The inside of the motor was clean as a whistle and the one rocker had the slightest of damage barely noticeable. the remaining valvetrain was imaculent. I would recommend this product for your Penstar engines

Been using Amsoil sig series 5W30 with Amsoil filter and now at 365,000 miles on my 2012 Tacoma V-6 4WD. Im going for 500,000.

The 2.4L in the 2007 Accord is running smooth and quiet. Inside the oil fill hole it is as clean as new. Great product and will continue to use.

Watched a YouTube comparison of top line oils. Amsoil beat them all hands down. Car runs smoother and mileage is better.

excellent oil highly recommend it to friends change it every 12000-15000 or 1 yr. have never burned any oil between oil changes

I have used AMZOIL filters/oil/and bypass systems in all my trucks, and most my cars/motorcycles. My '86 Jeep Comanche is going on 320K, my 2008 is going on 210K, I just converted my 2019 Alfa to AMZOIL and got a slightly longer filter to supersede the original/add extra oil capacity since a bypass won't fit. I hope to get long, trouble-free life out the Alfa as I have my other vehicles.

Great product. Have used the oil, transmission oil, and rear axial oil. All work great.

This oil is great it has cut down on how often I need to change my oil and also helps with better gas mileage bye to less friction

Good product bad sales tactics. Amsoil always sends me the promotional codes after I have placed an order. When I try to use the promotional codes on later orders it tells me those promotions have expired. Pretty shady if you ask me.
