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

Love the 2.5 gallon containers. Ordered 3 jugs so I could knock out my dad’s oil change as well as mine. My truck likes the oil just fine. Looking forward to doing some analysis on it between 8-10 k on miles.

Best oil for the Best price.

Awesome Product! The ONLY oil I use in all my diesel engines in Alaska!

I switched my 04’ 6.0 from normal 15w40 to this full synthetic 5w40. It made my injectors so much more quieter. At the time when i switched it was mid summer in Northern California, 110° + days aren’t uncommon… I never had an issue with oil pressure or oil temps. Since then, we’ve moved to Washington. Haven’t had any super super cold mornings but it’s gotten in the low 30’s and the truck has had 0 issues firing right up. Would definitely recommend!

Used in Ford 6.0 , truck runs better and sounds better. Now I use it in all my diesel engines

Great oil works good in my truck as well as everything else we run it in

I use this oil for my F350 6.0 powerstroke to prevent coking in the injectors, as people know the HUEI injection systems are hard on oil. Truck has 220k miles on it without an issue. Also recently purchased a Tiffin RV with the ISC 8.3 (pre def), I am running this oil in that engine with great results too! Price is competitive with other major brands, but I get the amsoil quality.

Great product so far will continue to use

Somewhat hesitant to leave the review, as if Im being completely honest the timing looks terrible. We changed the oil in Pops' '15 Ram 1500 Ecodiesel, and after months of struggling..he said it ran better than it ever had. Now, I hesitated to write this as about a week later, the ecodiesel did what it does best, and failed. Metal in the oil, more noise than a high school hallway..but I don't think it's related to the oil, based on the ecodiesel reputation. Would I buy the oil again? Absolutely. Just not the engine.
