I accidentally ordered the wrong product and didn't realize it until after it was sent. Customer service told me how to return it and I reordered the product I needed.

I use it in my 1999 kubota B1700 runs like a top . It’s starts easy in cold weather and like top quality oil. Highly recommend AMSOIL products !

As the title states. We’ve all invested hard earned money in our vehicles, doesn’t make sense to mistreat them.

After I started using this oil in my 6.7 powerstoke I have noticed a 1 mpg gain and smoother idling. This engine oil is the best stuff on earth in my opinion and with a $70,000 truck this is the only oil it deserves. You put good in and good will come out.

The best

I've been an Amsoil customer since 2008 and have never regretted purchasing any of the Amsoil products. I've used Amsoil in my RAM 2500 diesel gas cars/trucks, motorcycles and lawn equipment. All of their oils and filters are first rate. Will be a customer for many years to come.

Just did 3rd oil change using Amsoil instead of OEM in F250 Powerstroke. It lasts longer, the engine runs slightly quieter and I'm confident in the better quality.

Very fast delivery as always.

This is the only oil I’ll use in my truck.

Purchased a brand new 2024 Cummins 6.7 Was having a slight tic @ 2k miles on it Dealer said it was fine Changed oil @3k miles and filter with this amsoil and it’s super quiet and idles much smoother Love amsoil and all there products

I use this oil in my F-350 Diesel Pickup and in my 2021 Western Star Semi. I use to use Shell Rotella T5 10W30. I decided to give Amsoil 10W30 a try and I will never go back. Very good oil!

This is the best oil on the market

this oil gives me confidence that my 6.7 power stroke will stay healthy my f550 is my service truck and my lively hood i can't afford to use nothing but the best thanks AMSOIL

I switched to AMSOil syn for my diesel trucks in 2010 based on commentary from my mechanic. basically, after 250K miles, another engine looked brand new without any sludge visible.... seems to be working for me....

Seems to be excellent oil, we will see how it is after 500 hrs.

This is my first time using this product it’s supposedly the best on the market I’ll find out

I’ve been ordering this oil ever since I got my truck. I have 90k miles on my truck and it’s running smooth .

Amazing oil, my truck loves it.

Just a change of oil and my truck idles better and just runs smooth going down the street. After many years of using whatever oil, making the switch has changed my mind. Wife’s truck next.

Trusted by the trucking industry for as long as I can remember. Amsoil is the best oil for any diesel vehicle application.
