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!!!

Normal, quick, and easy order process and quick receipt.

It is expensive, but the ability to change once per year is cost effective. Good oil, engine parts appear clean and wear free!

I've tried all brands of oil from Mobil1 to Royal Purple and by far Amsoil is the best. I can really feel and see the difference. My engine runs cooler with Amsoil and even when I changed it at 25,000 miles it still looked better than all the oils I tried and I changed them at 5,000 miles.

Great oil I change out at 7500 on a GMC Terrain 3.0L. Never had any problems summer or winter. I have 50,000 on engine no serious issues with engine other than regular oil changes. Very happy with this oil

I use this in my gt500. I push the car hard knowing Signature Series has got me covered.

Since I had just purchased a seven year old car with 105,000 miles on it,and not knowing when any of the fluids were last changed. The dealer would not change any of the fluids before and after I purchased this vehicle stating that since the vehicle was not at the factory's recommended change interval (mileage wise) they refused to change any fluid.So, I took it upon myself and I proceded to change out ALL of the vehicle's fluid's.Saving myself hundred's upon hundred's of dollars doing the work myself. As it turned out I chose Amsoil products and even though its only been a month since I changed out these fluids I have NOT regreted my decision.I feel that these product's that Amsoil offer's are by far the best to use for your car...

I use the amsoil products because they are the best of the best , use on my guns, the signature series in my car and filters, great stuff. Try it you won't be disappointed

Been using in my 2004 Chevy Silverado for years!! Works great.
