Customer Ratings & Reviews

All my cars (well, except for the ones with mileage above 400,000 km) and motorcycles get synthetic oils in them. When I can get Amsoil, that is my oil of choice. Amsoil has been my desired oil for years. Is it better than any other brand of synthetic oil? I don't know from experience, however synthetic oils help my vehicles run cooler, and I believe that synthetic lubricants provide a more consistent layer of lubrication under all conditions of use.

Recently switched to 5W30XL on my GMC Canyon after trying Royal Purple. My truck runs smoother and I'll stick with AMSOIL. Do wish there was an AMSOIL filter available for my 2017 3.6 Canyon. I'd use 5W30 Signature Series.

I use this product in a1990 f150 300 inline 6. I use only Amsoil products because they where the frost in synthetic oil and only synthetic. They did not convert from conventional oil to synthetic like all the other oil companies. I remember when Amsoil came out in the 70's.

You can trust it to do its job

I have used Amsoil motor oil, transmission fluid, brake fluid, and gear oil in my vehicle for 118, 000 miles now. I feel it is protecting my vehicle very well.

Keeps my engine clean and running smooth

I can see an improvement in gas mileage I can hear the difference in sound and feel the better performance as the miles build up.

Love that I can change my oil once or twice a year.

Hands down the best money can buy

I have been using Amsoil for about two years now. I recently purchased the XL 0W-20 for my wife's SUV and my commuting car. The product arrives quickly and performs great! I enjoy being able to order the oil filters and other additives all at the same time.

I use amsoil products when ever I can

I use this oil in all my vehicles Five old chevy trucks my boat Dirt bike and my wife's new car. This is the best oil on the market.

Is AMSOIL expensive, yeah a little, but if you sign up for the Preferred Customer it not bad. I'm definitely a pay a little more in maintenance and avoid having to pay a lot in repairs. I used to buy the AMSOIL Signature version of the 0W-20 that my truck calls for, but I switched to this to save about 50% on the cost. I get about 6k miles between oil changes (changing at the 20% oil life remaining mark) and it appears I'll get that same interval maybe a bit more (maybe 500-750 extra miles) with this grade oil vice the Signature. I would buy again for sure.

I originally test the full synthetic in my High mileage Pathfinder and then the XL Boost in my F150 both products have performed above and beyond my expectations.

Good oil for a budget but don't want to skip on quality

Been using Amsoil in this one for a while. Smooth winter time starts, no engine noise.

I use Amsoil on both my vehicles and boat. I drive and fish in some very remote areas so I want worry free operation. Amsoil gives me that peace of mind.

I have been a customer for Amzoil for over 12 years and will continue to do so as I believe it is the best oil money can buy.

Solid product, love using it
