Customer Ratings & Reviews

This is the best oil on the market worth the purchase price.

I've been using this oil for many years now. I have a Toyota Corolla and I can go a full year without loosing a drop of oil. In part the engine is mechanically sound. Used to use on 2007 Scion TC until car got totaled and 5W-30 on prior 1996 Mystique.

Been using Amsoil in our Honda cars and SUV’s since 2008. The hybrid and SUV have been flawless.

This oil is great in my GT350 best oil I have ever used.

I’ve switched to Amsoil and I won’t look back love this oil.

I've got almost 550,000km on my car and it runs great. Love Amsoil products

I've been using Amsoil for years and love there products. Would highly recommend them to anyone that wants to protect there ride.

I tried to take advantage of free shipping recently and entered the promo code on the website. I even got a message saying it would be applied at checkout. It was not. The oil is of excellent quality and it was shipped quickly, I'm just disappointed that their "deal" was bogus.

Good product long interval change.

I drive an average of 66 miles a day just for work alone. This product definitely goes the distance with adding after 9,000 miles & a little later on totalling 3/4qt more to top off for the entire year. The color reminds me of coffee that seems to suspend & encapsulate particulate well within so there wouldn't be much of any gludge from settlement. A guy I know did an acidic test at 14 months to see how it holds up & it passed even though it wasn't recommended to run past a year. I use magnetic drain plugs & the metal goop was extremely minimal. It's just the best option for those who drive more than the average Joe. If you work a ride share company, this is your brand for sure. On a side note: The expended product can be a very useful chain saw lube as it seems to minimize blade track wear even when there would be massive miles on it. It's just amazing oil.

I have been using Amsoil products in my vehicles for quite some , and always have been very happy with the quality and performance of your products, My only complaint would be, as you reminded me several times "to use my points" because that promotion was ending soon, when I tried to redeem them during my last order, I was either doing something wrong, or the website wasn't allowing me to use them, it was a minimal amount, so it's not a huge deal, so if I had one complaint, then that would be it, Hey, YOU ASKED!

I've used these products in all my atvs,motorcycles and vehicles for years and never had a problem I've even took apart some of the engines and noticed less ware on cylinder walls and other parts very expressive

BEST THERE IS, DON'T SETTLE FOR LESS !! VERY FAST SHIPPING..

I have used this oil in lots of vehicles for a long time. The multi viscosity feature of this oil doesn't break down. The 0 viscosity means the car will start all winter without plugging the car in. I change oil every 10,000 km and have never had engine problems.

Really good oil but the bottle os not easy to use/pour, it will be good idea if Amsoil create a friendly bottle to use.

I’ve been using Amsoil synthetics in all of my engines for over 20 years and highly recommend them. I also use their synthetic greases for all vehicles and equipment.

very good

This is simply the best oil in the world. No other way to put it. Its probably to good for a daily driver but it gives me the piece of mind.

Quick delivery of an awesome product, used for many years now trouble free

Great oil, Always starts outside in the winter, and the vehicle uses no oil between oil changes.
