I have used this oil product since 2005 and love this synthetic old for the long life between oil changes.

The engine is running smoother and has more pep...greater response!

Have used Amsoil Signature in all of our vehicles/equipment and have never encountered engine wear issues

This oil makes a noticeable difference in cold temperature starts. The engine turns over easier leading to faster starts with less battery draw. The longer time between oil changes helps, also.

I use AMSOIL in all my equipment. Cars motorcycle, diesel work truck, power washer and generator. There is absolutely no way to go wrong using the best there is. So that's why I do it

I strictly only run this Amsoil in all my cars I would never run anything else. I use it in my 1986 Subaru Brat GL, 2002 Subaru WRX, and in my 2009 Toyota Tacoma TRD Sport. I recommend this oil to anyone who only wants the best for their cars or trucks.

Used in a 2016 chevy spark.

Once a year oil changes since car was new.

I have been using AMSOIL now for about ten years. I have been very satisfied with the quality and affordability of this oil. Will continue to use in all of my vehicles. I purchased a new 2016 Silverado and immediately replaced the engine oil with AMSOIL.

Have been using Ams oil for years especially in my 2011 Kia optima which now has 226000 miles. Die to the extended drain intervals has saved me lots of money and my engine still runs like the day I bought it.

Went to the 6mo. oil change ( 2) time and the oil after 6 months still looks clean.

I don't have any technical information, but I'm happy with the performance and mileage I'm getting in my Silverdado with a combined highway and stop and go daily commute.

I've been using this in my vehicles for years and it's always proved valuable! I notice quieter engines, improved fuel economy, and better protection. Had it analyzed in several types of engines and driving conditions and it's been an outstanding performer. Other oils do not keep the quality and consistency over the years like this does. It's the first thing I do too any new vehicle I get.

I have 311,000 miles on my little insight. Change the oil every 10000 miles or so. Not a single problem with it. Product always delivered very quickly. good stuff.

I have used only AMSoil since 1982, best I have ever used.

Total reliability. Better fuel economy, cleaner engine, longer mechanical life. One higher priced change per year, but only one per year. Best product guarantee in the industry!

Use this for our 2009 VW Routan SEL Premium with 4.0L, and the van loves it! We have taken it up and down west coast numerous times without an issue!

Since we changed to Amsoil the mpg has gone up 5 mile /gallon extra on average. Plus in winter it is easier to start with the vehicle being parked out doors, huge difference. Change oil less frequently we can put on 20,000 miles/year seeing how I am in accounting if you extrapolate that experience over the millions of vehicles in the US, we could as a country save a ton of oil in petroleum used to lubricate and better gas mileage, what if the government alone changed to synthetics, wow.

Have several very hi mileage vehicles.. jeep with 300k Two F series trucks 300k & 400 k. So when we purchased new truck we put the signature series 5-20 and an Ea. filter on it. We feel pretty good about it.

Used in my f150 ecoboost engine, makes it run smooth, cool, quiet.
