I use it in all of my diesel trucks and equipment for wear protection

Just switched over to this for my diesel pusher motorhome. Can’t wait to see how it will run now.

So far it is doing better than any oil I have used,time will tell .

I use this in my 2005 Powerstroke and have been using it sine the truck was new.

Amsoil is the only oil that I use. In my opinion it is the best oil on the market.

Very good oil use in all vehicles

Put it in my 99 F250 with 249000 miles on it. I have run it approximately 1000 miles and the 7.3 powerstroke is quieter. Seems to start easier. Anxious to see how it holds up pulling our camper. So far love it!!! My only problem is I have made 2 orders and I have not received any free items that I was supposed to. But very satisfied with the oil!!!

Improved my fuel economy by about .3 mpg on my 2017 L5P Duramax over shell rotunda. Been using it for 30k miles with 4-5k change intervals. Fuel economy gains seem to diminish after 5k and I’ll suddenly burn a half a quart around that 4-5k mark then I change it. I realize I can get more miles out of this oil but it gets super dirty from the emissions puking back through the crankcase and I really like peace of mind! It’s great oil and I recommend to anyone.

Love your synthetic products.

The oil is great. However, my promo prize was sent to the wrong address.

After my distributor moved, I had to resort to using Rotella until I found a new one. I've used Amsoil for about 6 years. It is more expensive, but after sinking $11,000 into my truck for new injectors and other upgrades it's all I use. I trust it to keep my truck running like new. It has 220k miles and runs great. We pull a fifth wheel in the spring, summer and fall. I have NEVER had to add oil. My operating temperature is always steady and there is a difference in noise reduction with Amsoil. The extra money is worth peace of mind to just get in and go anywhere. I'm a customer for life.

Engine seems to run quieter on Amsoil. Love the 10 quart jug.

I have switched everything I own o er to Amsoil. Thus product in particular, has improved my 2005 W-900 wear metals by 70% according to wix oil analysis. I e seen a difference in fuel mileage, & rough start ups as well. I run this oil 30-35k miles. I change all filters @ 15-18k & top off!! Also have an Amsoil oil bypass system in that helps

this diesel oil is good. better than Mobil 1.

In my Professional Opinion as a Skilled Tradesman with 35+ years experience I absolutely rate and choose Amsoil products #1. I use Amsoil in everything I own, from my Duramax Diesel Daily Driver to my Classic 1952 Chevrolet "Super-Charged" C10 Pickup. I know and Trust Amsoil Products is the Best Protection my Money can buy! Respectfully, John Richard 🇺🇸🇨🇦

this oil by far is the best for my diesel engine. what i do not like is getting weekly, bi-weekly emails with continual free offers from the company when you buy something. it is not like i need to buy oil every few weeks. but i continue to get offers. why not make a list of free offers so when you do buy product and meet a certain dollar value -- you have a list of promotional material to choose from as a free gift from Amsoil. Pick one!!! i would of liked the bottle koozies - which were offered after i placed my order. i did get free shipping which is appreciated, but the continual marketing promotional offers need to be addressed and consolidated. no complaints with the product at all.

The oil holds up in all conditions a good bit more Money but seems to be well worth it in the long run for the engine. 7.3 Ford motor

Been using it for years

Love this stuff for my 6.4 powerstroke. I used T6 previously and I prefer this over it. At the end of 5000 miles, I believe this oil is in better shape. I’ll continue to use this and will be swapping my differentials over to AMSOIL at the next change. Thanks!!

Always a great product
