Great Oil!! Hard to believe a Oil change would make so much difference but IT does! Great oil!! Our Vehicles run better and better! I tell all my friends about it.

To bad can't buy locally. One great product.

Proudly use AMSOIL products

I run this oil in my boosted truck and work trucks and can't praise it enough!! This is the only oil that i trust!!

I've used Amsoil in my previous Silverado of 18 years which was running great when I sold it and a new truck. Logged over 220K miles and never had an issue with oil leaks or major engine trouble.

I did the switch from a competitor to AMSOIL over a year ago now. This not only meet expectations but surpassed them. Love being to go long between changes which saves money as well.

Running quitter, longer and better fuel economy.

I have Amsoil in everything from my air compressors to my weed eater. Every truck, car and boat I have ever owned has used it, and my 2 street rods have used it since I built them in 1990! If you want the best, like me, then this is the oils for you! I refuse to use anything else...

I use this product as my regular run of the mill oil for my daily driver autos. We put about 2500 miles per car per month.

The perfect oil fom the mileage I drive.

So far I have a good impression but I will reserve my comment till my next change.

Have been using Amsoil for the past year and I feel a difference in my vehicle. It's runs so much better, especially when it gets really hot and cold here in Vegas.

No noticeable difference in power like some have told me, but it is still a good oil and keeps my fuel economy up. Will definitely buy again and I recommend this or the Signature Series to others. I wish they made this weight (10W-40) in Signature Series.

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.
