Customer Ratings & Reviews

I use only Amsoil in every engine I own. My F150, the wife's Lincoln, the Harley, The Boss Hoss, My Shelby, My vintage Ford tractor (Z-Rod)The Toro zero turn My 1981 Briggs and Straton edger and anything else that stops by my home.

I have used this oil for 4 years now in my 2005 F150. Each December I change the oil myself and send samples to Blackstone Labs for analysis. Each time it has come back, saying I can extend my oil changes another 5K+ miles because the TBN is great. Has always been over 2. The most I have driven in any 1 year period before changing oil was 14K miles. I'm impressed.

I use it in all my gas powered vehicles

The new formula is working out very well in our ecoboost applications.

As a do it yourself auto maintenance gear head, I value the peace of mind knowing I am using the best oil available for extended drain intervals.

This oil in my truck Hemi 5.7 2017 run perfect !

Only change once a year

Best oil on market use it in all my vehicles for years no issues

20,000 miles on an oil change will get me through for a year so I only have to change my oil once a year. It pays for itself and its less maintenance I have to worry about doing.

Amsoil products are everything Amsoil say they are. They are simply the best and most effective products of their types, regardless whether it's oil, additives, etc... While conventional oils can be good and do what you need it to, they just don't compare to Amsoil synthetic lubricants. They can't. That's the whole reason synthetic lubricants were developed in the first place. When turbine engines were in development, conventional lubricants would completely fail. Engines would literally come apart...catastrophic failure. I've run Amsoil in every car I've had. I change it once a year; reduced waste, superior protection and longevity, lower cost. It's a no-brainer.

Drive 1 hour Clermont to Orlando back and forth every weekday. Already 300,000 miles. My car responds like a new car. There are 5 cars in our household. I had to change oil 4 times a year per car. That was 4x5=20 oil changes. Now I change oil once a year, usually on the same day!

I'v used this oil for over 25 years.

25000 miles with a warranty! Incredible but thanks Amsoil

We use your product in our (2) cars and our 2500 truck. After burning the oil in our transmit ion in a previous motor home, we switched to AMS andhad NO further oil problems .

My dad has used AmsOil for close to 40 years. I just switched about 6 Months ago. I use it in all of my vehicles including my Work van that i use to pull a 5000lb trailer and is on the road all the time, stop and go!

Its what I need. And I will be buying more for the other vehicles

Save me money and gives me peace of mind

Just one oil change in a year.

WE ONLY PUT ABOUT 6K MILES A YEAR ON OUR VEHICLES SO AN ANNUAL OIL CHANGE WORKS FINE AND SAVES LABOR. I HAVE A BYPASS FILTER SETUP (BP90) ON MY TRUCK SO NO WORRIES THERE, UP TO 248K IF MEMORY SERVES.

My mechanic says that the Amsoil 5W-20 oil and filter is the best thing, other than keeping the car clean, that I can do for my Charger. I agree with my mechanic.
