Great oil and injector cleaner.Sample oil at 20000 Kim’s and consistently comes back as no change needed.I change anyways but it speaks for the quality of the product.

always had good success with amsoil esp. when I lived in MN, for cold weather starts.

Better than anything else out there. The only product I will use in my wife’s SUV.

Trying for first time in our cold weather conditions,So far been doing good.Real test will be when it’s -10 degrees.

I've used AMS Oil since 2012....my car runs great....customer service is great...helps me with all my needs...thanks

I started using Amsoil back in my motorcycle days (sadly ended by health problems). Amsoil was able to keep carbon and crud from collecting in the valve covers of my BMW twins, and it held up even after being fried in summer traffic jams. It flowed just fine at 20 deg., which was as cold as I'd ride to work. I'd kick the engine over twice, then hit the electric start. No drama. I want (and get) that quality in my cars. I am at the age where I never want to buy another car, and with Amsoil oils and additives, I know that I am maximizing the lifespans of my machines.

Lifters are quieter, also changed diff and transfer case oil. Haven't yet determined if mpg improved any.

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.
