I use this oil in my 2013 F150 with the eco-boost 3.5L engine. Truck burns or uses zero oil between oil changes(once a year). I only drive about 7,000 miles a year. I use Amsoil because I know Amsoil makes the best products available.

Customer for 7 months. I can't say anything someone else hasn't said already. This was for my Dad's girlfriend car. We have my truck, his truck, her SUV, my mower all on amsoil. My truck is all done. Engine, tranny, rear end, transfer case. Waiting to put in coolant. It sells itself. They say everything drives.i use signature series and will never use anything else in any motor I ever own.dealerahips can say whatever they want, just stinks you have to change within a certain mileage to keep warranty cause this oil goes forever compared to rest. Use it and see!!!!

Been using AMSOIL since the 70's in many cars and trucks. Sold one truck to a mechanic after 204K miles. He said it was the cleanest engine he' ever seen.

I chose to go 0-40 for both cold flow and film strength at the running temps. Motor is getting cleaner every oil change and is running great. I tow with confidence and will continue to run the first in synthetics

Back in 2006 I have swivhed from other brands to Amsoil. Based on some independent test results, and most importantly a friend. Who have tested his 12000 mile oil being Amsoil, on 45000 mile vehicle, that used amsoil since new. Test results sugested fillowing: 1) oil is 6000-7000 mile old 2) engine is 15000-25000 miles old 3) if lubrication continues as before, engine should ladt over 300000 miles. That was enough info for me to switch, also Mobil 1 that I was using at the time, came with less promising test results. Since the switch I have been using Amsoil in every car, and truck I owned. Never had a failure due to lubrication. And most importantly have saved a bunch of money, on changing oil once per year. Signature series, along with EA filter can last up to 25000 miles. I would never go past 15000 miles.

I have a 05 ram 2500 HD 250000 miles on it still runs like a dream

The highest quality oil for everything with and engine, hands down.

I've used Amsoil over the last 30 plus years and never had a problem with any of the product. I use it in offroad vehicles, 4x4 Jeeps, turbo charged engines, NA engines and anything else that benefits from a high quality synthetic lubricant.

I have used Amsoil signature oil for over a 100,000 miles in my vehicle. I tried other oils but they did not last or perform up to my standards.

I can go a long time between oil changes with the signature series 5W 20 oil, it is amazing how much better my truck has been running since I have been using it. I haven't found a con with it yet, just all pros!

I have used Amsoil for many years, I use it in all my vehicles everything from my daily driver to my classic and antique cars, I even order it for my friends and family who all love how it works and the convenience of use ie. Once a year oil change.

I started using AMS Oil over 30 years ago, and left it for awhile. I tried Mobile 1 but did not like how it performed in my vehicles, I bought a new F-150 with eco-boost which I read runs higher in temperature, so came back to AMS Oil because it always held up better under extreme conditions. I have had the truck for over 2 years now and it knows nothing but AMSOil. I really feel I will get the performance and years I want out of my truck with the help from AMSOil.

AMSOIL Signature Series 5W-30 Motor Oil keeps my car running smoothly.

I use Amsoil for the peace of mind it gives me in my cars, trucks, motorcycles, generators, and lawn equipment. I have a 1985 Craftsman lawn mower that has never had anything but Amsoil in it and the motor is still going strong! That's proof enough for me.

I use the product in my 2013 Dodge Ram 5.7L. I believe I have increased fuel mileage and the truck runs great!

I have used Amsoil products since 2003. Never a problem. I have recommended it to friends without any qualms.

Ever since discovering this oil in 2005 I've never used anything else, and it's never let me down. 15k miles between oil changes and it's still gold in color not black like others.

I have been using Amsoil for years. Commutes for me is 40 to 50 kms oneway and I can run Amsoil and never have to add oil. Had an old car overheat in Calgary one summer due to traffic on the deerfoot trail and there was no problem afterwards with the car or the oil.
