My late husband and I were farmers and only used Amsoil in our equipment. Now i use the same oil in my pickup as i want to have it for many years. I also use it in my motorcycles. Excellent product for the motors I care about.
I have used Amsoil exclusively in all my vehicles for close to 30 yrs., and I'm happy!
Bottom Line
Yes, I would recommend this to a friend.

Been a preferred member for many years, but price on this keeps going up.
Considering not using anymore. Ten bucks a quart was my max. Too bad I loved this company and products, just can’t do it anymore.
I have been using AMSOIL in all my vehicles and motorized equipment for years now and I can honestly say I have yet to experience any issues of wear, and know it has extended the life of all the motors.
Been using AMSOIL for 3 years now and I can honestly say it’s the best on the market my 3 vehicles run much quieter and smoother I highly recommend AMSOIL can’t go wrong with AMSOIL.
Was introduced to this product about 2yra ago. I had been using Mobile One which was good however, after using this product in my Lexus, I began using AMSOIL in my wife’s car. Both cars run smoother and along with Upper Cylinder & PI gas treatments, I’ll never go back to Mobile One. Great U.S.A. quality product!

This is my first time using any Amsoil product, but I decided to use it for the used Camaro SS I just bought. I have no idea what oil was used before, but I wanted to change it to Amsoil based on a number of recommendations I saw for my particular car. I may end up using this stuff in my other cars as well.
The Signature series oil is definitely top shelf oil. I have been using it in my Focus since 150k miles. I am now at 461k miles on the car. This oil keeps it going. Less oil changes, since you can run more miles, is a time saver and money saver. I will not use any other kind of oil.
Best oil great for Turbos made for my car I love it better than mobile 1 penzoil valvoleen. I love the thickness and its true synthetic great quality.will not use anything else
Been using amsoil on my vehicles for years now and I’ve never had an issue with the product or my order.
Bottom Line
Yes, I would recommend this to a friend.

My vehicle purrs like a kitten with the Signature Series and the extra price is well worth the peace of mind that my engine is well protected and will give me many more years of service, especially in today's bad economy. I can't afford another car.
What can I say except Amsoil is the best with shipping within 2 days i always have my order and it has always been exactly what i order. This oil is second to none, since using it I have never had one mechanical engine problem where oil would be an issue. I use it in every motor i own from lawnmowers, sxs, to automobiles. Will never use anything else.
Ive started doing my own maintenance on our vehicles and when I've tried out different types of oil, this was felt different. With many research and reviews, having this oil definitely makes a performance difference and I am at ease when I say I've found my true, best and quality vehicle oil in the market for life. True engineering work!
