Customer Ratings & Reviews

This is the oil I use in my vehicles, great product and highly recommend.

Used to use a different, but my friend informed me about this oil and since that day Amsoil is the only oil I use.

Great stuff. Have a 2012 Silverado that occasionally had valvetrain tap on cold start. Haven’t had it happen since the switch

Amsoil is the ONLY oil I use on my cars, and motorcycle. I truly believe it's the best.

AMSOIL signature series is the only oil my vehicles have received in at least 15 years. Although the recommended weight for my Subaru Outback is 5W-30, I use this oil for additional cold start flow. With an EA 15K filter, it's the perfect solution for once per year oil and filter service.

I have used this type oil and recommended oil filter on my 2012 Honda Accord V6 coupe after the initial Honda oil used for the first 10k miles. I change both oil and filter every 20k miles. I change the auto transmission fluid every 100k. I also normal maintenance as per Honda specs. I rarely if ever add any fluids between changes. As of today 03/07/21 the Accord has 343,000 miles and counting!! No repairs or replacement of motor or trans. Great products!! Great car!!

I am amazed at the difference an oil can make. My engine runs much smoother and I have seen an increase in mileage. I have gained approximately 35-40 miles per tank.

When you want the best Noticeable difference.

There’s no competition hands down best lubricity on the market. Do yourself a favor and make the switch to amsoil. Thank you for a superior product!!!

Great oil. My Mechanic says this oil is the best for protection and anti clogging he's seen. keeps everything clean. Turbo benefits too

Using amsoil signature series 0W30 on my 2018 ford raptor 3.5 ecoboost during colder months from Oct - April, our winter temps are as low as ‐40⁰C. I switch all my vehicles to 0W30 SS during these cold months.

Fast shipping.Great products. I've been using Amsoil in all my vehicles and toys for last twenty years.Even my lawn mower.Best oil ever!

Great longevity, I go 10K between changes ,..

Fast Shipping and quality product! You can never go wrong using AMSOIL Synthetic Motor Oil. Never had motor issues while using this product!

This is the absolute best motor oil on earth! Soon after I started using this oil for my 2002 Lexus ES300, I noticed all kinds of improvements with the performance of my engine. Granted Toyota makes excellent vehicles, this oil still brings it to the next level. I now have 380,000kms on my car and it runs like a clock! I can't even hear my engine when I sit at red lights!! Completely dependable motor oil by the inventors of synthetic motor oil. Using anything else just doesn't make sense to me. Please note that I do not work for, or have any affiliation with Amsoil, and I'm not getting paid for the statement I just made. It's truly based on my personal experience with this motor oil.
