Customer Ratings & Reviews

Twice, out of curiosity, I sent samples to a lab for analysis after 16K miles of use. Both times all viscosity and additive levels showed I could run the oil for several thousand more miles. That is with towing, highway and local use mix. Contamination levels also lower than tolerances thanks to amsoil filter. I change oil no more than once a year. Sometimes almost 2 years in my 2002 Toyota Sequoia. Great products.

Use for my Toyota Tundra Truck V8 change one a year due to low mileage. Works great no oil usage and provides great protection.

My first time using this particular product and I am blown away by its performance. Within just the first few minutes of using this product. I immediately noticed my engine idling much smoother and it sounded better harmonically as well. Like it was more in tune and moving freer. I've never had automotive product work so well, ever. Great job AMSOil team. In my opinion well worth the money. I was using Subaru premium synthetic motor oil for the past 2 years with full service included. My vehicle only has about 20K on it and is very well kept. And I still noticed a tremendous difference. Bravo Zulu

I put this oil in my 2017 Ram. I had 90,000 miles on it. Now it has 93,000 on it. Compared to Penzoil Platinum oil when I put a few thousand miles on it, Amsoil still looks new. I plan on putting 5,000 more miles on it. I'll see how it looks then.

Keeps my engine running clean and smooth!

Great oil and competitively priced to other synthetics if you are a preferred customer.

Great

I have been using Amsoil in all my vehicles for the past 10 years and engines run smooth and stay clean.

best oil

2500 miles on a GDI turbo KIA Forte - I drive my car hard and the oil still looks and feels like I just put it in.

I've been using this 0w-40 in an engine that normally calls for 5w-30 weight oil. It gives the easier running when engine is warming to full temperature, and lowers oil consumption when engine is fully warmed up. I started using this weight at 220K. Now the vehicle has 278K. Still runs very good!

I tested this oil for a little over a year in a customer's Hyundai Accent. This vehicle has 82,000 miles on it. The 0w-30 results in lower oil consumption. The owner is pleased with how the car runs. This is also a long life motor oil, which is good because the customer sometimes exceeds the recommended oil change interval.

Just switched two vehicles from Mobil 1 to Amsoil. I'm not an expert by any means, but the smoothness and clarity of the Amsoil was impressive. Both vehicles seem to be holding stronger oil pressure. I'm a newbie to this company, but at this point, I'm planning to go strictly Amsoil from now on--can't wait to buy some for my John Deere!

i have use amsoil since 2004. first auto was a Honda Odyssey. 230K miles on it before i sold it and at that time i never had to add oil between oil changes (once a year). have used it on every car i have owned since then, including my children's cars, and between all of those auto have logged over half a million miles with no oil related problems.

Meets, exceeds specifications and is High quality synthetic oil! Highly recommended!

Best oil on the market.

I'm cheap, I don't like to overspend and I hate having to fix my cars (I work in a lube shop) I do my own yearly and love it. Most other synthetic oils only last 1/4 of the length.

515,000km on my 2005 Civic and still runs like a top, change the oil every 40,000km or yearly, whatever comes first. Been doing that since about 60,000km and love it. Wanna save money? Run Amsoil!

Slick

Same great oil, in a bigger jug.
