Customer Ratings & Reviews

This is all I run in my 2010 Camaro SS.

Great oil...no promotions....no hat coozie...nutting.

This product is the best I have found. 145000 miles and it still runs great!

I have been using this oil for approximately 10 years. I never had any oil related issue. Engine is quiet with this oil and appears clean inside.

I use 0-20 in Tundra, Highlander, has worked well in both. I also use 10-40 in my motorcycle 0-20 in my atv I am happy with all of it.

I have been using Amsoil products since 1983. This oil has been used in both our New Toyota's Very pleased with performance and lubrication of these engines

I use this oil in all my vehicles

This is the first time I've used amsoil. I got signature series 5w30 for my big horsepower 2011 Camaro SS that I run strictly at the track. It's held up really good so far. I'm going to try the race oil next change.

Only a month in, but I’m confident it will work as expected. Researched through 3rd party and their testing shows AMSOIL is the leader. Save money with doing fewer oil changes. 5 ⭐️

We run this oil in both our 2022 Ram TRX and the 2022 Ram Power Wagon we have seen mpg improvement in both truck we swear by Amsoil

Love the 0w-30 SS Oil. I mix 1 quart of SS 0w-30 with 4 quarts of SS 0w-20 for my 2.4L Honda engine to achieve what I think is a 'thick' 0w-20 mix. Works great! Love the results. Engine just tripped over 300,000 miles and is performing like brand-new. Only major work done on the engine has been replaced timing chain & guides at 220,000 miles. It has majority of its life on Amsoil... with some OCI's with Mobil 1 Ext Prot and Valvoline Ext Perf. Have been on Amsoil for the last 20,000 miles since last experiment of Mobil 1 EP. Will not be doing any more of those comparisons... the Honda engine does better on Amsoil SS.

Love this Oil. Keeps my 300,000 mile Honda engine clean and purring like a kitten. Just finished a 525 mile roadtrip and achieved 38 mpg ... which is up about 3-4 mpg in similar roadtrips when using Valvoline Ext Perf 0w-20 oil. Will not continue any further experiments with other oil brands like I have done in the past. Will stick with Amsoil SS.

Have used Amsol Oil all the cars life. Has 193,400 miles on it without any engine problems.

You get what you pay for. Became a member a few years back. Love my Tacoma 2015 sport, and therefore I give it the best I believe I can get. Have done some research and feel this is the best oil 4 my Taco. Made in the USA. Loyal customer, much love, PMA.

I use AMSOIL products in every one of my vehicles. Best product on the market.

Best performance and durability

A money saver with extended drain. Great protection from friction and heat.

My wifes car runs so much smoother. I love that it's 100% synthetic and I don't have to change her oil every 5k miles. Eben is the reason I switched to AMSOIL.

This is by far the best oil I have ever used! Have used Mobil One but for roughly the same price you get a much better overall performance product with Amsoil. Every 5K miles I change my oil so for me it’s roughly 2 changes a year so the confidence of knowing I have an amazing oil plus the protection of Amsoil makes me happy!!

Engine is running so much smoother after swapping.
