Customer Ratings & Reviews

Amsoil is the only oil I use in my cars and it is far superior to the other brands.

I use the motor oil in my small engines and my vehicles engines and transmissions, I started when my dad used the 100:1 2 cycle oil in chainsaws back in the late 70's

I tried Amsoil when I noticed high consumption rates in my wifes car. With Amsoil there was less oil consumption and the oil doesn't break down as noticably. I just ordered Amsoil XL5W30 for my truck and spare car. I even have it i my lawn mowers.

Excellent oil that meets or exceeds OEM specs. Keeps engine well protected under daily use and the occasional track days, when engine is use and abuse. On engines that I have inspected internally looked in good shape and tear and wear are minimal

I've been using this in my Nissan Murano for over 40,000 miles. I can't beat it for the price and fuel mileage gains.

It is a very good oil keep my engine clean and quite no sludge anywhere

I use this in my 1996 G.M.C. K 1500, and my 2004 Toyota Highlander Limited all wheel drive. NEVER had a product problem. I generally change the Oil Filter (with an Amsoil filter) at 5k, top off, do a complete oil change at 10k, I use nothing but Amsoil products in my vehicles. Between the two, there are over 300k on the vehicles! I also use this oil in my lawnmower.. I know I'm not supposed to, but,, it works! I just change it every new mowing season.

Accidently ran car with just 1 quart of Amsoil in. Not a problem after.

Makes my truck run excellent that's way it has 120, 000

Amsoil 10w-40 in my F150 with 200K miles in her and still runs like new

I have used Amsoil products for years, and will never change!!! I only use Amsoil in my GMC P/U my Chevy HHR and my Harley I also use only Amsoil air and oil filter..

With the outrageous prices for new cars these days, I don't plan on purchasing a new vehicle any time in the near future. Instead, I plan on keeping my current vehicles (5) running for a very very long time and trust no other motor oil to help me do that other than Amsoil's XL synthetic oils.

Last truck was a 2004 F250 crew cab with the 5.4 liter v8. Started using it after 10k miles and all the way till 204000 miles (hard miles) when I sold it. It never leaked or used any oil. I changed it every 6k and the truck ran as strong when I sold it as the day I bought it.

Proof is in the pudding ,,, or this case the oil !

I personally put amsoil in my three cats . This oil made a believer out of me when I tried it in my old Dodge caravan and the motor sound like new . That old click I used to hear on the motor when idling was gone .

My race car was setup with total Amsoil lubricantion. From front to back. Bearing grease ,transmission, differential,engine oil.......... All my street vehicles also ran on Amsoil. Never had a failure. Great products . I also has some racing oil left over that I run my mower on .

I use Amsoil for my personal and commercial vehicles. It has surpass and improved all the vehicles I use on a daily basis.

Recommend this product too all!!!

Great chemicals and oil highly recommend

Use in 2015 Camero. Get great mileage out of it.
