TRIAX Fleet Ultra 15W-40 CK-4 API Licensed Synthetic Blend, Moly and Boron Performance Boosted, Heavy Duty Diesel Engine Oil, OEM Compatible with Volvo, Mack, Cummins, DD (5 Gallon)

Absolutely love this oil for my 99 Ford F250 Super Duty 7.3. I decided to try this about a year ago and it does a great job. I also use the Archoil additive and have never had any leakage issues and my temperatures are great. My injectors seem quieter with this oil than with regular oil and it does a great job keeping everything clean. When I removed my valve covers I didn’t have any grime or anything on the inside of the covers or in any spots on the heads. For the price of this oil I used to get about 4 gallons so it’s a great value for the money…plus you get another bucket to use around the shop or house when you clean all the oils out.

Changed to this oil in my 2000 f250 7.3 w 314k miles on it [only 17 miles ago] and it already starts faster cold and seems quieter as well. hoping for better mileage and longer engine life. driving 300 miles tomorrow so I will let you know more after that. ……………..So...., 309 miles. 17.4mpg. was only getting around 15.5 before, tried to keep my speed below 65 and let the engine torque do all the work. engine noise is down too. ...Im very happy with this oil. 1/18/2019 update... continues to start faster than before, runs better, quieter and making me happy. no more rotella or delo for me! update 2/26/22 Still using this oil, best 7.3 oil I've ever used. Update 6/8/22 Still love this oil, used on a friends 2002 f350 7.3, he said his truck was never this quiet. I change my oil at 7500 miles due to it only being used for towing and short trips in town, would definitely keep it in over 10k if lots of hiway use. 11/29/2024, still buying this oil, love it. wish s7 was still available.

Installed this oil late in 2018. Wanted to wait to review it until I had 6,000 miles and two oil analyses on it. As most of you know the Ford 6.0 L diesel is hard on oil, shears it down from 15W/40 to 15W/30 in a heart beat. Well, not this oil. After 6,000 miles of towing at 19,000 GVW this oil is still 15W/40 and has a TBN of 5.2. Which means it could have gone another 6,000 miles, no problem. I have changed the transmission and rear end over to Triax products as well. Nothing better!

Use for my motorhome Cat C7. Price is secondary to all benefits. This oil is outstanding and way better running compared to Rotella, Delco and others. If any it is comparable with Delvac Very smooth idle and overall performance. Will not go back to other brand's

Great product at a great price… Got it for my 1999 F-250 Powerstroke Diesel… Working well so far and my oil consumption has decreased and engine cranks better and runs smoother..

I ordered two 5 gallon containers and only received one 5 gallon container. It wouldn't be that big a deal if I didn't need all 10 gallons for an oil change. I got an email saying there was a problem shipping the other one but never heard what the hold up was so I returned the other 5 gallon container for a full refund. Never again will I order from Triax!

This Oil is the perfect companion to a oil pan flush out and filter change! I used some Hotshot additive to mix and my truck quit smoking at start up and had rapid throttle response. Buying in bulk saved me $$ in long run! Totally happy with this Product!!
