Customer Ratings & Reviews

Great stuff as always! Good filter too. I use Amsoil in all my vehicles

Forums recommended amsoil for my 2007 Toyota Tundra with 224k miles on it. It quieted the líderes immediately with start ups. Quality oil!

I use it in all my cars and SUV Subarus Crosstrek and differential systems

I love that this oil helps my pick up to get better fuel milage. I have a big block V8, 8.1 liter, Im need all the help I can get.

Amsoil is one of the best products on the market. With independent testing Amsoil oil consistently rated at the top .

I have used Amsoil for all of my vehicles for over 20 years. It may be a little more expensive, but it last longer and has the full backing of the manufacturer. Something you don't see much anymore!

This oil never disappoints I've been using it for over 10 yrs and some of the High performance cars I've had didn't burn a bit of Amsoil but did other brands! Amsoil is True and Tested!

Still going strong at 70000

I've been using this for several years now and have no complaints or issues.

I use this in my 2014 Ford raptor 6.2L I noticed better gas mileage and a smoother running engine. I have been using Amsoil for several years now and I use it in every I own from generac generator to my diesel tractors. All of my equipment run smooth and my whole house generator runs cooler.

Best oil, been using it for years

Perfect fit for my GT 500, engine runs smoothly and effectively.

Great product for the price.

Very good oil I put it on my 96 Corolla and she runs better and vibrates less I'm going to continue using it

Amsoil Signature Series is great engine oil. I have used it for over twenty years in my cars and trucks, without an engine problem. I replace it every 15,000 miles and my engines run as good as new and are as clean as new after well over a hundred thousand miles.

I have been using Amsoil products for about 13 years and found them to be superior to regular ones. The oil is awesome and I give it credit for extending my oil changes longer and saving $$$ on that. The gas additives also improve MPG in all my vehicles too, 3 cars and 2 motorcycles. Regular oil analysis confirms the oil is doing its job without damage to my engines. I believe Amsoil is far better than any other synthetic oil on the market and way better than conventional oils.

This is hand down the best oil. What a difference over the dexos. I only run Amsoil in everything I own including my Honda lawn mower.

I use this blended with 0W-40 in the hot summer months in my nearly 200k miles MB R350 to keep the HTHS higher for better protection.
