Customer Ratings & Reviews

Excellent oil. For years I have used this oil in my cars and have never had a problem and my cars have a lot of mileage and still run like new.

Solid company, great protection quality OIL !

Great oil and great service

I was try to see how this oil work but surprise me wonderful and boost my truck. Love it. Great chose.

The best oil on the planet!

Manufacturer required synthetic oil and no longer than 7500 miles between oil changes. This oil fit perfectly. MPG went up by 3.

I use this oil in all my vehicles. Just bought amsoil for my atv's

Been using Amsoil in car since I bought New. Car has 80,000 miles and runs great. I change oil every 10,000 miles with no problems..!!

Always a fan of Amsoil products.

In addition to having the Oil Filter to allow me to go 12,000 miles between oil changes, the AmsOil XL Boosted motor oil is so much better than OEM oil which came in my 2016 GMC Yukon Denali. Thetruck funs smooth as silk and I think its getting better MPG!! Nice!

Great product never had any issues, I always feel a since of comfort using Amsoil products!

Always a remarkable change in sound when changing typical oil to Amsoil. We have gone to Amsoil for all our vehicles. This 0W-20, is used for our Suburban. Wouldn't choose anything else. Record your vehicle's sound before changing. Then play it after you've added Amsoil. You'll be amazed.

I send all my oil in my Infiniti G37 Sedan for lab testing, and Amsoil has surprised me and outperformed Mobil 1, Castrol, Motul, Liqui Molly, and Royal Purple. Least wear of any other oil I have tried — especially iron.

Amsoil is quality worth its cost! My car runs quieter and smoother.

I really love amsoil and definitely would recommend it. Only the best for my vehicles.

i have used amsoil products for a few years now. my riding mowers after a full season oil almost as clear as it was new. i use it in all 4 strokes, weed eater, power washer, tiller, air compressor, vehicles. instantly noticed the oil doesn't look burnt after 12 months in the vehicles. I'm 110% satisfied with their products. engine oil, trans fluid, transfer case/ptu, rear differential, brake fluid, etc. might cost more but if it ain't broke don't change brands. i personally have done some testing of my own. with heating, friction, viscosity and have yet to find anything comparable. I'm staying with amsoil. so whats a few extra bucks a year. i cut my engine filters open and check the pleats for metal particles and wear. always come out clean. also is better with engine sludge build up. what else to say. I'm good to go.

As a courier driver I drive over 500 miles a night M-F. My car currently has a bit over 370,500 miles and last year I put 130k miles on my car. I use Amsoil XT because I believe it offers the best protection for my engine and with 12,000 mile intervals it is very economical. Even at 12,000 miles, the engine oil looks far cleaner than conventional oils at 3,000 miles or other synthetics at 5,000 miles. Only oil I'll use.

So far so good. It sounds like my truck has power

Have been using for many years on my 2014 GMC Sierra. Always consistent mileage and power.

Amazing products that you can trust
