Customer Ratings & Reviews

I use Amsoil in all of my vehicles. I have found it saves fuel and makes my engines run much smoother and cooler. I have proved the use to many friends with my Harley's showing them how ell they perform also.

Oil seems to work very well . This is the second oil change with it - so we'll see how it goes from here

Great product

I really have enjoyed the switch to synthetic, I was super pumped to open up my kit in the mail.

Just turned 120,000 miles and the engine is very quiet and runs like new.

Bar none, Amziol products are the absolute best you can buy! For everything you own, farm, lawn and garden , cars, trucks

I used Amsoil Signature for the first time in my wife's Elantra and it runs much smoother at idle than it did with Mobile 1.

Excellent engine protection with the long term performance provided by Amsoil. Consistently better mileage than any other lubrication product. Would recommend to anyone wanting the absolute best in engine protection and lubrication.

My go to oil for 05 and 10 Impala. Used Amsoil since buying the cars with approx 60,000 km on each. 40,000 km oil changes within 12 months with a filter change at around the 20K km mark. I had 345K on the 10 Impala when the transmission gave out - motor was strong. The 05 is still running well with over 395K kms. Has to have something to do with good quality oil.

I only use Amsoil. Wouldn't waste my time, money or vehicles on anything else.

I have used this for a few years now and has provided the best protection out of all the oils out there for me.

After seeing the test results of all the popular motor oils, I was convinced there is no better choice for me than AMSOIL. For years I was under the impression that Mobile 1 was the best - how wrong I was.

When I purchased my 2014 Tundra, I asked the dealership service writer I have known for 25 years for a recommendation regarding motor oil. He suggested Amsoil. I have been using Amsoil in my Tundra since October '13; I also use Amsoil in my Highlander, my wife's Camry, my Honda lawn mower, and in my John Deere Diesel garden tractor. So far, everything still runs like new.

I run Amsoil in my truck and snowmobile.

Never in doubt...

My car runs way better and bring out lots of power

My bmw 328 run super great ... incredible in cold temperature....thanks

Hands down the best oil I've ever used in all my trucks and suvs I saw improvements in fuel mileage Lower rpm at idle Cooler temperatures I will never use anything else but Amsoil

Signature Series oil is unbelievable. I have had multiple vehicles with two hundred to three hundred twenty-five thousand miles on them and Amsoil keep clean like new. I also have 22 and 38 year old tractors that use no oil.

I use Amsoil Signature Series in all of my cars, from my truck, daily drivers and four various Porsche models. Nothing better and I will never switch!
