I know exactly how Amsoil will perform in my 2017, F-150, 3.5L/twin turbo. I have used Amsoil for decades and have never had an oil-related problem with any of my engines. Amazing chemistry...that's for sure.

I purchased a used 1996 Chevrolet C2500 with 341,000 miles on it. The previous owner said that he only used AMSOIL. So I drove the truck for a thousand miles then changed the oil with AMSOIL. It must work, the truck has the original engine, original transmission and the original exhaust system

This oil is spectacular! Somehow I failed to check the oil level in my wife's '08 Honda Accord 3.5L V-6 and when I did check it, it only had 2 out of the required 4.5 quarts! ; o I have not noticed any damage to the engine system since and count my blessings as she would have kicked my rear if anything would have happened to her beloved car! Thank you Amsoil for such an awesome product!!! You are a wifesaver!!! ; ) This idiot makes certain to check the oil level in her car now!!!!!

This oil is fantastic. I run it to its max service interval with the right filter so I change once a year. Cold start temps down to -35C in winter without plugging in and has never let me down.

Simply perfection in motor oil.

Have used Amsoil for the past 15 years. During that time, it has never let me down. Early on, I had oil analysis done and the oil held up extremely well going over 20,000 real miles and still had life left. You can't ask more then that especially in a dusty environment.

Product was delivered on a very timely fashion. I go through the bother of ordering online because the product is the best.

Have a 5.3 that I bought did first oil change and ran valvoline full synthetic burned 2qts in 2000 miles. On my 5 oil change with amsoil and burned 1/2qt in 3000 miles. 5.3 are known for burning oil due to oil injectors clogging but running amsoil seems to have made a huge difference.

I buy this oil for my family SUV and so far is doing the job done

best oil ive ever put in my car

I use it in all my vehicles. Since none of of them go over 25,000 miles per year, I change the oil every March with Amsoil filters. The engines stay clean and, along with occasion PE, they all run very well.

I love putting the 5w-20 Signature series motor oil in my 2017 Jeep Cherokee. I trust it just like I trust the AMSOIL products I use in all my vehicles.

I have been using AMSOIL for the past 40 years. I fully trust any product with the AMSOIL logo on it. I use it on anything that requires any kind of lubrication. It truelly is the best.

oil changes

It's the only brand I'll trust in my turbo vehicle. Oil seems to maintain it's qualities great and the old stuff still feels good when changing after 6,000 miles.

I've been using this product in my 2010 F150 sence in was new great product temp stays down in the heat of summer and easy starts in the brutal cold days in the hart of the winter.

Use in all my vehicles, and it definitely helps with the fuel economy.

I'm very picky about the oil I run in all my vehicles. I have a first generation miata with very low miles that only gets fed this oil. It comes out very useable and clean still even after about 7500 miles that I run it too which consists of a lot of very high engine speed at 4k and above.

Once I tried amsoil 0w-20 signature series for the first time in my first car I loved how smooth it had run and how it just doesn't break down like other oils , ive switched all my family vehicles to amsoil and they love the oil change intervals plus they love the price I can get it for ,I will continue using oil the best oil on the market that has the reputation I want to keep my vehicles going for a lifetime

My engine runs cooler, oil pressure is 6 to 8 pounds higher couldn't be happier!!!
