Noticable difference in offroad motor. Pressure tends to stay stable after long hours on hot days on rock crawling trails

Excellent oil for all my vehicles!

Always used synthetics (petroleum based), but after 500 miles using the SS 5W20 on a 2017 5.0 Coyote with 20K, no burn-off, and seems as clean as when I put it in. So far so good!

Amsoil is one of the best Synthetics on the market. IT can be used in higher mileage vehicles , and I have noticed no bad side effects when this is done. I have done so on more than one higfh mileage rig. The mileage gains seem to happen more when it is implemented with newer vehicles. I advise putting Amsoil product on ALL gearboxes on your vehicle. Other synthetics I have tried will result in the engine starting to consume oil, when it was not doing so with conventional oil. I have never had this happen when switching to Amsoil. I am also using the Synthetic 2 stroke in small engines which is highly rated to perform at 80:1.

I have used this product for the past two decades and it has become the only product to get into my engine

Great product fast shipping

Noticeable difference in sound and feel after change. Slight improvement on mpg for a V8. Even half way through the life of the oil, still very clean.

I know my engine is protected. This oil is amazing oil. I used to use valvoline. But I’m an Amsoil guy for life. I know my engine is protected using high quality products.

I use the Signature 10W-30 in my 2015 Ford F-150 Lariat SuperCrew 2WD w/3.5 EcoBoost and 3.15:1 gears. I also use a dual remote oil filtration on my engine. I chose the 10W-30 over the recommended 5W-30 due to the lower volatility rate of the 10W-30. No issues for 5 years. I average 25.4 MPG on the highway. With the average fuel savings using AMSOIL, to me it's like getting my oil changes for free.

I have used this in my two Toyota vehicles for the last 7 years. I have never had any oil usage between oil changes and it goes the recommended distance.

I have been using Amsoil in my vehicles for over 12 years have reading about its properties. I wanted to look after my investments the right way and I will use nothing but Amsoil.

I was forced to use AMSOil in 1980 for a blueprinted VW engine; the valve train was wearing quickly. As soon as the rings seated, I switched to AMSOil and the wear stopped. I've used the 5W30 in my 89 GMC K1500 since break-in, and will continue to do so.

This oil, 5W30 SS, like all AmsOil products are outstanding. I have been a dealer/preferred customer for 39 years and have found nothing better. The tech support is equally outstanding. The only problem I have is changing the oil myself, I am 78 and on Oxygen 24/7 (but I do it anyway). I Keep vehicles a long time (22 to 26 years). I used to change my oil every 3,ooo miles. Now I do it once a year or longer. Thanks guys, keep it up.

I wish I would of known about amsoil and the attention to detail of their products with the science backed knowledge. Awesome stuff and makes the cars perform top notch

Awesome product used them all my life

Switched to this oil on my 2017 Ford Expedition EL XLT. Average gas mileage increased from 18.1 to 20.2!! Expensive? Not really! My oil change shops charge me 115.00 for a premium oil change and there is no telling “what” they put in my truck. This oil change along with the amsoil filter was 120.00! I am going to let it go for 15K and that means it just cut the price in half compare to the 7.5k I was doing before!
