Customer Ratings & Reviews

I was introduced to AMSOIL in 1989 and ever since then it's all I use. I've had dealerships and Auto parts houses try to sell me Royal Purple and Penzoil and Mobil One and I stop them before they even get going good. And I tell them, "Sorry that you like trashy oil in your prized possessions but as for me I only run the best, and that's Amsoil. It's been around since the 60's and it's never failed. So, why not use something that stands the test of TIME!!? That's why I use it, I "Know" it won't fail."

I bought SS 5W-30 and a 15K filter for less than 4 oil changes

Run it in every vehicle I own and my kids. Best product on the market

Time in between changes

Works great lasts a long time !!!! Over priced though

We have a 2016 Honda Pilot and a 2014 Jeep Gtand Cherokee. The Pilot gets 28 mpg and the Jeep gets 24. I truelly believe it's because of AMSOIL. When we picked up my wife's Pilot from the dealer I told her that within 30 days i'll have it running so smooth that she won't know that it's running. She gave me the bonehead look. Long story short, both vehicles run as smooth as silk and the mpg's are higher since AMSOIL. Not long ago i got into her truck and i didn't know it was running. I asked her if she was going to start the truck before we leave for our trip. That's basically how the story goes for all of our cars; lawn equipment and anything that uses oil. It's the best you can get.

My vehicles definitely feels it has more performance.

Best synthetic oil in the world it's the best and only oil we use.

It's the best

Use it in my 2000 Honda civic SI with 220000 miles on it. Still runs like a champ.

Use in my Toyota Tundra since new 2006! 270,000 mi. Great protection, runs well & very consistent!

Awesome oil! After changing the oil in my wife traverse to Amsoil everything has been running smoother. The only down side is sometimes my wife will start the car waiting for me to leave the house, I'll get in the car and try and crank it again because I cant hear the engine running it's so quiet now.

Great oil, change it once a year. Been buying Amsoil since 1980, first as just a customer and then as preferred. I use only Amsoil oils, gear oils in tractor, small engines.

I've been using Amsoil for around 18 years, it's never let me down. When I get in a pinch, I might resort to another quality oil but I can always tell it's not Amsoil and drain it asap. I choose to run the Signature series for the extended drain and additive packs, but i still drain between 3 and 5 thousand mile intervals. Some will say I'm wasting money, I say it makes me happy and it's peace of mind. I've used this in many turbo applications, big displacement NA motors, hypersport bikes, and cruisers. Currently I'm running this in my first turbo gasoline direct injection vehicle and it's been great. Only other oil I would use for a turbo GDI application is Redline synthetics. Remember Amsoil is one of the only true full synthetic motor oils, most claim to be, but are not. My advice, become a preferred customer, buy oil by the case and save a bundle with free shipping to boot.

I use it in my 2 wheel drive 4Runner and have 273,000 miles on the car all with AMSOIL.

Amazing oil for the Toyota FJ. FJ ran better and oil at change interval didn't seem as dark.

Nothing on the market that beats it

I started using amzoil products before being called amsoil. I use the signature series oil and Eo and Eat filters. I change my oil once/yr. And I literally do not burn any oil in that yr. With my 00' tundra V8 using amsoil. My 02

I have been using Amsoil products in my vehicles and motorized equipment for many years and relay on its quality. As a "gearhead", I know how important using quality motor oils and greases are to machinery. They are my first choice for lubrication fluids.

I've taken several engines apart but only engines that have run Amsoil and they only need coolant system work. Conventional oil precipitates out garbage and sludges up engines resulting in CLOGGED oil passages. If your switching from conventional, get the best protection you can get that has tons of positive history. Do your homework/research to understand ALL the costs involved. You will determine Amsoil is the best switch you can make for your vehicles.
