Customer Ratings & Reviews

Excellent service and pricing for a really rather excellent product. I’ve been using this on my 2017 GT350 for 6 months now and it has been brilliant so far.

Hello, I have been using Amsoil Signature series ow-20 for my 2017 Toyota Tundra. This oil performs better and last longer than anything else on the market. My truck runs better than new. Oil changes are a breeze and it provides a maximum amount of protection for the engine. I have total confidence whether I'm running at high speed down the interstate or idling in bumper to bumper traffic that the engine is totally protected all of the time. I am definitely a customer for life. I feel that Amsoil has put the time and dedication and research into making a superior product for consumers.

Great Oil and Filter. Would not use anything else. Worth the money

Run Amsoil in every vehicle, believe in the protection it gives

Amsoil is the bees knees. It really is worth investing in the best synthetic oil money can buy. I've enjoyed an increase in fuel economy, power and peace of mind. I'd recommend switching to anyone.

We use the signature series oil because I like the cost effective performance of changing my oil once a year. I drive around 12000 miles a year. Cold weather starts are also better with this product.

Have a nissan frontier with 353000km ...been using amsoil lubricants and truck runs like a sewing machine!

Keeps my engine clean, while lubricating all the necessary parts. I am a big fan of quality products, so what I use in my vehicles is no different. I usually change my oil every 10k miles in my 2016 Power Wagon. I have that confidence because I look at the oil that comes out. Never have I seen or smelled burned oil.

I service 7 auto and really like the once a year oil changes. Amsoil has been tested and highly recommended in the Mustang community for its great qualities. I use 5W 20, 5W 30 and 5W 50 exclusively for many years now and very glad I did! The Best oil and filters by far, keep up the great job!!! Joe...

The best oil since motor oil🏌🏿‍♂️

Great oil, but not sure I want to go 25,000 miles on it. I've gone 18,000 and did another oil change. At 18,000 oil was black and I just didn't trust it anymore. I think next time I'll change at 15,000, not pushing it more than that.

i have been using this oil for years will not use any thing else

Great quality oil from day 1! Had to source oil after a track mishap back in August. Car ran great and all the numbers were spot on.

I use this 0-20 signature in my 2020 4 runner also in a 2020 Honda Civic awesome product get you some. Don’t compromise with the cheaper oils out there if you’re keeping your vehicle long term.

I’ve been using Amsoil oil and products for more than 20 years. Never a breakdown, higher fuel mileage, quieter running and peace of mind.

I've been using Amsoil 5w30 (among other viscosities too!) for over a decade. When I first switched over to using it on my turbo Miata, I did a few Blackstone oil analyses at oil changes. After 5k miles there was plenty of oil life left & TBN! My friends laugh at me that I kept my OCI @ 5k miles, even though the Amsoil could easily do 10k miles, but its cheap piece of mind! Always recommend Amsoil to all my friends & family!

My order was delivered very fast. Thank you

The best oil on the planet

This in my opinion is the best oil on the market. I have used all amsoil fluids in my 1992 Harley and just recently bought a 1988 iroc that I will be changing all the fluids to amsoil.

tried this and some of the competitors 5w-30 synthetic oil, this stuff outperforms everything else by a mile.
