Use it in all my vehicles. I beleive ya the only way to go

personal vehicle use, engine purrs like a kitten improved mileage

Been using Amsoil for 20 years and never had any engine problems.

I have used this oil for years. In my 06 Durango. It has over 230,000 miles and is still going.

have been using for years now always works better then other oil brands that i have used and its just great only having to do it once a year

I always use Amsoil in my vehicles and have had outstanding performance from it

I can only speak honestly and being that I just acquired the vehicle I changed the oil and transmission fluid recently to Amsoil. Both products seem fine but I cannot really say that they made any noticeable improvement in mileage or smoothness or anything else however I'm hoping they do provide the protection I'm looking for and continue to keep my vehicle running great for many years to come.

Amsoil is a superior product. I use it on all my vehicles and every time I convert a vehicle to amsoil it always runs smoother then it was prior to the swap.

I've been using Amsoil since 2009 in all of my power equipment from cars, motorcycles, lawn equipment, snow removal, generators and etc. I won't use anything else.

I started using aimsoil in my car a year or so after I bought it. I drive a lot, 400,000 + miles on my car at this time and still going! Know I use aimsoil in my tractor also.

Only oil I have used in over 45 years of changing oil, That after 18000 miles still has plenty of protection left in the oil. Got to use a good quality filter as well, but this oil is awesome

Pay a little more and get a whole lot. I use Amsoil in my transmission, rear diff and engine. World of difference. I track my car as well and believe me I'm hard on my driveline. Gears, transmission and engine perform at optimum levels with Amsoil and you are protected. If it's used in racecars it's for a reason.

I have used this product for years and now starting to use it in my lawn equipment. I have had no problems.

I have discovered about amsoil about 2 years ago, and from then and now. I have switched to amsoil for all my vehicles. Especially my 96 Jeep grand Cherokee. I had to change my oil every 2months because it was burning the oil really fast. Till i made the switch, 8 months and the oil is still in good condition. This product sure made my money's worth. I really recommend this brand of oil.

I've used Amsoil products for years. If you understand the product technical reports, You will use this oil and filter combination. Best for wear, cleaning and longevity I've ever found. Lubricity is second to none.

Use in both personal and now work vehicle. Can't go wrong with extended drain intervals, pays off fast.

This oil has made a noticeable difference in my hemi. It's made the engine quieter and given me better overall gas mileage. You can't go wrong with the right oil.

I always order signature series for every oil change on all my vehicles and very been disappointed with the protection.

Of course anyone who has done any research on motor oils realizes that AMSOIL motor oils are superior to anything else on the market. I like all their products however I am upset at their recent price increases. I'm not sure why they continue to raise prices as the majority of us retired people never get a cost of living increases in our income. Please don't tell me it's R & D or material and labor increases to justify the increase.

I run amsoil in every motorized vehicle I own...very happy with all products
