TriaxFleet Ultra ESP 10W-30 API CK-4 Licensed Synthetic Blend, Moly and Boron Performance Boosted, Heavy Duty Diesel Engine Oil, Compatible with Volvo, Mack, Cummins, DD (5 Gallon)

Faster cold startsTurbo spools up quicker then everAlmost 1mpg betterNo additive needed = huge cost savingsI don’t usually write reviews unless I’m very impressed. This oil flowed great at -30f in MNEngine runs quieter. I was using motorcraft 10w30 diesel oil before. 3500mi on the triax so far as seems to run better and better. I will change it at 5000mi and sent in for a UOA.Ran this oil for 8000mi with no issues and a good UOA. I could not do that with Rotella, Delo or Motorcraft all with rev-x or archoil I’ve used before finding this oil. I’ll keep using this from now on.

I have used synthetic diesel oil since it became available in my 20 year old Kubota front end loader/backhoe. This oil meets all the modern specs for almost any diesel in the construction field. Buying in bulk (5 gallons), the price works out to a little more than $4 a quart delivered! Can’t beat that.

This is a great alternative to going fully synthetic by selecting a blend. I would def recommend Triax, it has all the detergents and additives a much more expensive oil would have for a lot less money, I use it in my 02 7.3l with 400k miles and absolutely love this motor oil.

I have 2 Ford Super duty trucks and I use this oil in the winter months. I use Triax oil in all my vehicles and for the price and premium additives, it can't be beat

Great oil motor runs quieter cooler little better mpg longer oil change intervals

Best 10w30 synblend on the market,

Best diesel oil out there! I had a 6.0 powerstroke with stiction issues and this oil cleared it up. No need for additional additives. Now I have a 2016 duramax and she purrs like a kitten. Gained 1.5mpg over generic diesel oil. Cant even tell its running til the fan kicks on. No joke I well never put anything else in my diesel as long as this stuff is available. P.S. I am using the 5w40
