Customer Ratings & Reviews

Using my personal vehicle. Stands up to hot and cold temperatures well. I like longer intervals of oil changes

Awesome product. Use it on both my car's.

I use Amsoil in everything I own that has an engine( mower, snowblower, generator, compressor, truck, and minivan). What sold me was during harsh cold winter months (-25 to -35 Celsius) my truck kinda turned over slow for the first turn of the engine before firing right up using conventional oil. Thought what heck let's see how it works with synthetic oil during the winter..... long story short I use it all year round and won't ever switch back.

Have been using Amsoil for the past four years and I'm very satisfied. My cars even seem to sound better. Amsoil gives me peace of mind knowing my cars are functioning better. It's worth the extra money just because it prolongs the life of the engines

I love this oil. My truck runs smooth and does great on long trips!

Started using Amsoil in 2004 but was skeptical about the advertising claims. I would change my oil and send off a sample to have it analyzed. The results always came back showing that the oil was still good. I use the Amsoil EA oil filters also an have complete confidence in my engine lubrication. I use Amsoil products in all of my vehicles transmissions, differentials, etc.

This amsoil since I use it the car run as New and is millag. On gas saved me money it's a good oil for

I use this oil in my 1.6L off road car here in the Arizona heat. It runs quieter and smoother than anything I've used. In these severe conditions it excels beyond my expectations.

I first tried this in my personal daily driver and liked it so much I'm now running this oil in three cars. Also running the racing oil, transmission fluid and gear oil in my race car!

I have used AmsOil oil since 2006 i trucks, performance cars and SUV's. I love the extended drain intervals with AmsOil oil filters. When I replaced an oil pan gasket the shop was surprised how clean the oil pan was with 100,000+ miles on a 2003 Escape. Be advised when I switched to AmsOil in the 2003 Escape it had 80,000 miles on it and I used the AmsOil flush as well before first fill with AmsOil. The combination of Also oil and gear lubricants kept the 2003 Escape getting the sticker MPG new or better. I have so used this with a 2007 350Z and a 2006 Dodge 1500 5.7 Hemi with bypass filter set up.

I've been using Amsoil for over 15 years and Hands down its the best I use Amsoils in everything that requires oil It's works !!!

This oil is long lasting and keeps on slipping!

I have a 2016 GMC Sierra cam, DoD delete and procharger. Change it every 5k just to be safe it being boosted and no issues at all. I love this stuff!!

very good product and knowledgeable people about their product.

Over the past five months I have purchased oil for three cars, transmission fluid for four cars, and engine flush for three, as well as bottle pumps for oil and transmission fluid. In the next month I will be purchasing oil and transmission fluid for two more vehicles. As you can see I'm impressed with Amsoil products so much that I keep buying them for family. It's important to take care of the vehicles that my loved ones drive, because if they break down the result can undesirable.

Just built a blown LS 383 stroker for my 05 sierra. I have used other synthetics in the past, my builder recommended amsoil and i took his advice. Also use in my 70 nova SS with a stroker 496

I use this product for maintenance oil changes.

I have been using Amsoil for over 10 yrs. now and I have never had a problem with anything. For my money, this is the best Synthetic Oil you can buy and got he longest distance between oil changes! I wouldn't use anything else in any of my Lincoln Town Car's, MKS's or Cadillac's. Once you do the research on Amsoil and the benefits your car will receive, I think you will be very satisfied as I have been for yrs.

1-once-a-year oil changes, and the BEST-protection for your investment,! PERIOD! need I have to explain anything else,..?

For vehicle engine longevity I don't mess with conventional motor oil any longer. Why even bother risking the heart of your vehicle.
