Only oil I will put on my Ram 2500

Been using since pretty much day one!

Great oil! The bottles make it easy to pour.

sticking to what works and what has been used in the truck before me

I have been using this exclusively in my 2016 F350. It out performs the Motorcraft Oil by a large margin. I drive lots of short trips. The Florida temps in Spring, Summer and Fall are routinely above 90°F. The severe service schedule suits me for my driving style.

I have always had a feint clicking from my Diesel. Put Amsoil in for the first time and no more clicking (knocking)

Truck seems to run a lot smoother so far only put about 500 miles on it so time will tell

Great oil always in stock but the filter has not been in stock for a while now and that's not cool forcing me to use doc diesel. Can you guys catch up with filter orders on a 2024 f 350 please

I use AMSOIL exclusively in all my vehicles and in my son’s vehicles as well.

Love the AMS oil difference! My oil temps run a few degrees cooler when towing in this hot summer sun! Thanks AMS

I noticed on the Amsoil website when you add your make and model truck and your address it will automatically put the exact product for your vehicle in front of you. I have a 2021 Ram with the 6.7 Cummins that has the hydraulic lifters that are oil specific and I live in Oregon with more temperatures and the website put the 10W-30 that is the preferred oil grade by Cummins for the 6.7 with hydraulic lifters in my climate and how many parts counters are going to do that or let you walk out with 15-40. I have zero problem paying more for better oil in a vehicle that I you invest 80 to a 100K into.

Very fast service and great product

Not cheap, but I believe it is worth it…

Very happy with this diesel 10w30 stays clean longer better oil pressure fuel mileage is better engine seems happy.

This oil is top quality and based on test that I have read, it out performs other oil in engine protection.

I have not come across any AMSOIL products that haven’t lived up to their promises. The one pretty big thing is they are expensive, I wish they could offer a better discount for their preferred customers.

I run this year around in my 2016 Ford F350. It's a much better quality than OEM Motorcraft Synthetic and the cost difference is only a dollar or so per quart.

I heard about this product from a friend who had 2 trucks make it past 500k miles. I did my research and order kits for all 3 vehicles. I am happy with the cost and longevity of the product. I have been suggesting it to anyone that will listen.

Been running rotella for months, switched, and will never turn back.

i have used amsoil for 20+ years. this is the first diesel engine i have used it in. from the first crank up the idle has been smoother with a noticeable uptick in power. looking forward to many years of service from this equipment.
