If you use Rotella 15w-40, your oil turns deep black in the first 500 miles. If you use AMSOIL 15w-40, I am still waiting for oil breakdown. So far, 1500 miles. The oil looks like the same oil as I put in at 424k mile oil change interval. Rotella probably isn’t what you have been told. If you want a PSD 7.3L to work the way it was designed, use better oil. Try AMSOIL. It is the best.

Fast shipping and great customer service. All questions answered in a timely manner. Will continue to use this product for all my future oil needs .

Just a great product, this diesel oil was a noticeable difference in running cleaner then OE motorcraft

This is my go to oil for my 2015 F250 6.7 Powerstroke. I do this every 5,000 miles because I love my truck. I take care of it and it takes care of me!

I’ve done a lot of research using independent lab research and reviews about AMSOIL. In my opinion and by the information I have found, I have come to the conclusions that AMSOIL is the best money can buy.

One of best oil you can try in your truck

I use Amsoil in all of my vehicles, equipment and side x side. I swear by it. It costs just a little more but it is a superior oil.

Oil works great used it in my truck since new with no lifter issues or bearing issues factory uses 0-20w I run 5w-30 and no issues

Same price as a t6 Rotella and way better quality oil

I am impressed with this oil i put this in my 2021 jeep gladiator diesel it runs good cold starts better it will be the only oil I use from now on.

Great quality oil, truck seems to be running much better. Will do an oil analysis soon through blackstone.

It keeps my truck going strong. 220,000 miles and looking for that again.

Had a snow contract in this area. Worked the 6.4 diesel hard and non stop switching drivers. 24 hr work The engine smooth and as quiet as a diesel can be. No consumption in 2 weeks. Many hard km. Great product

Bought this for the power stroke 6.0. Winters get cold and find easier start with this product.

Awesome oil been using oil for 20 years in snowmobiles to trucks!!! Best oil ever

Run this stuff in all my small engines. May be an overkill but they work the very best.

I love this oil paired with Wix filter gives me confidence my engine is in good hands.

I’m using the oil in my semi truck 10w-30 ful synthetic, it’s a good stuff

Since using AMSOIL for my diesel has better gas mileage. That tells me everything I need to know about this oil compared to the part store brand. AMSOIL is the only oil I’m using in my diesel from now on

Been using this oil since I bought my JD back in 2016. All is well
