Started using Amsoil in my diesels years ago, quit spending money on nanoborate additives. Works great

It's nice to have promos. I love the products, but when the promo item isn't sent, it's a little frustrating. I ordered ahead of my scheduled time just to receive the promo item, so when it didn't come.............still love the oil though.

Great product! When I first got my powerstroke 4 yrs ago I had a tiny valve click. Used the 5-40 heavy duty diesel oil, tick gone!!! I won’t use anything else ! I used amsoil from my first oil change in my 6.4 powerstroke till now I highly suggest it!!

After trying many synthetics on the market, I got the best performance out of amsoil for my 6.0 powerstroke

2015 Ram 1500 Eco-diesel Running this oil because this engine needs the best to survive with the extremes these engines see with emission requirements!

best

Was delivered on time 3gals ordered going in to a Cummins 6.7 which holds 12qts then the oil was put in it was 1 quart low . 11quart

Been using Amsoil for about 8 years now in various vehicles. What drew me in was the product quality and reputation. I work a lot in remote areas and don't always have access to power for my block heater. Extreme cold weather starts have been made easier since I switched to the 5w-40.

The best Diesel motor oil I have ever used it’s awesome

It just feels good knowing I'm putting in quality oil in my truck! Oil is the lifeblood of your Truck. Take care of it

Love this oil motor runs smooth. Amsoil is a great product.

Great product been using it for awhile now!

amsoil is all in use in everything i drive

Great product. Takes the smoke out of the back end and makes cold starts effortless.

I used this oil for my first oil change (2022 F-350 Diesel). The engine starts and runs quieter than with the factory fill.

Love this stuff

Used to run rotella t6 but switched to this stuff ever since I discovered the preferred customer program and will never go back! Run it in my powerstroke and my tractor now as well

Many oils are not described about the abilities to protect the engine. Amsoil does. As well with filters like the two sets of Amsoil double filters I have installed on two trucks their filters are far superior in cleaning oil. Most products sold today are poor quality with advertising. Amsoil has stuck to consumer education and better products. All our equipment uses Amsoil oil and filters in order to avoid other oil company scams. We removed the 2015 6.7 diesel engine oil pan on a Ford F350 and with using Amsoil the pan inside was 100% clean, zero deposits. A larger oil pan was installed, no engine problems.

Don't waste your money on cheap oil, in the end you will save money.

It's a great product and a good value.
