Customer Ratings & Reviews

I use this in 3 of our vehicles,all use same oil and amsoil oil filters.Basically change the oil once a year.Best stuff out there!!!

One word AWESOME. I've been using this oil in all my cars for past 3 years, and it has never let me down.

Use this in my 2003 honda accord. 220,000 miles and going strong. No worries

Great fule mileage and consistent viscosity over 12,000 mile change interval in a 5.7 Hemi.

Everything i own that uses any type of oil gets amsoil.

While I was apprenticing to be a mechanic in the early 1980's a friend of mine challenged me to a comparison test between Amsoil 100% synthetic motor oils and conventional oil. As a result, I switched to Amsoil and have used it for over 30 years in all of my 4 stroke, 2 stroke, and diesel motors. It lasts longer, doesn't have the viscosity break down, and is a better lubricant than other oils.

I use my truck for work and personal time. I live in Toronto. Dealing with heavy traffic and temperaturea - 25 C at times, it takes a toll on the engine, very happy with the oil

Been using this oil since 2000 love it

If you look for quality, performance, fuel economy and peace of mind, don't bother to look elsewhere.

I use amsoil on all my cars weather it is brake fluid, trans. power steering and anti freeze.

I have been using this product since I bought my low milagr 2004 Mustang cobra back in 2013. I have trusted this product to protect my factory supercharged motor and it has done a great job. Happy with all my amsoil products. Loved there oil in my ATV's when I was younger and now I use there stuff in everything.

I run this oil the full year or 15,000 miles as i fall under severe service useage guidelines. It has always kept the inside of engine clean and i rarely add any oil,it performs well,oil analysis comes back great. Both vehicles i use it in have high miles and i know its keeping them running well. Highly recommended. Amsoil is the best oil in my opinion. I even use amsoil in my lawnmowers. Synthetics are not all equal. This is the best out there. I wrench for a living and have seen the effects of using sub par oil.

I use this oil in three of my vehicles and home generator. I have had nothing positive experiences with and definitely recommend it.

Great product, excellent service

My car has 140k miles and I've been changing my ea amsoil filter every 10k miles (rated for 15k miles) and my oil in my vehicle every 20k miles (rated for 25k miles) without fail. Excellent results and cheaper in the long run when compared to other conventional products.

Have used AMSOIL exclusively for 15 years in my vehicles. Have never had an oil related issue. This oil is especially good in my F150 eco boost engine. Smooth, quiet, economical performance. Best of the best!!

Excellent products! Just bought a 2017 Subaru Outback. Used Amsoil 0-20W and Amsoil Oil Filter. Long time consumer. Great stuff. Run in all of our family cars

Every auto I buy, Amsoil goes in along with their filters....

The oil is good, but with the membership fee and high shipping costs I am going back to Mobile 1 as I did not see much if any of a difference. There is just to many hoops they make you jump through. There should just be a cost to buy it and no membership fee that AMS Oil makes people think they are locked in to buying oil from them so they can "get the most of the membership". I think most people find annoying and just go buy another oil rather than pay high prices on top of shipping and also a fee just to buy it at a reasonable price.

Always use in my daily driver 4 years and 200,000 miles still smooth and strong
