Customer Ratings & Reviews

First time trying Amsoil in two different Fords, the 5.0l coyote was using some and stopped with Amsoil. The old crown Victoria sounds quieter on start up compared to Castrol Synthetic I was using.

Best product. Will not run anything else

They did synthetic first. It was the best then and still is. If you're going to keep your truck or car for years it's worth every penny.

Use this exclusively on our 2016 Prius V. Change the oil at 10k and now have over 90k on the car. Great product

Have been along time user of Amsoil products , never had a problem with any of the products. I have three high performance vehicles and use everything from oil and filters to brake fluid from Amsoil.

Amazing

It works great. My Jeep runs smoothly past 6000 miles

Replaced the eng oil with Amsoil. I could tell a difference from the get go. Amsoil is good stuff. Have a Subbie TX with a Turbo, this is the only oil I will ever use in this Subbie.

Gained 2mpg in my Ford f150. Works great.

Using this oil for past 5 years for our three Toyotas. The best oil so fur.

Love the signature 10 W 30 amazing how much quieter the engines get. I use the signature in my 2013 Honda Odyssey, 2007 Honda Accord, 1998 Honda Accord, and 2014 Subaru Crosstrek. Big fan of all Amsoil products.

I have used the Signature Series oil for many years. I only change it once a year on all my vehicles which will approach 25,000 miles on average. This is the only oil I will use and it has been fantastic!

Great oil for my vehicle. Silenced the ticking of the valves. Especially on initial start ups of the day.

Love this stuff!

Accurate and tested to be one of the best motor oil.
