Triax Fleet Supreme 15W-40 API CK-4 Full Synthetic Diesel Engine Oil | Friction Optimized and Boosted with Molybdenum & Nano-Boron | Superb Powerstroke Performance (5 Gallon)

This oil was perfect for my Kioti tractor

Use this in the summer months in my 7.3. Always quiets the injectors

muy buno tengo un cascadia del 2018 y desde k uso este aceite me suvio las revoluciones del motor y mayor rendimiento vale la pena el precio recxomendado 100 %

I bought a 5g bucket and my 2003 F250 loves it. I had been using a popular, more expensive synthetic 15W-40, and as soon as I changed the oil and fired it up, I could tell the difference in about 30 seconds as the injectors quieted down and seem to run smoother - so I changed the oil in my V8 Jeep, replaced it with this oil and BAM, same thing, it ran noticeably quieter and smoother.. and yes I realize it's a heavy oil to run in a gas motor but again the engine likes it. So I have 3 buckets stacked in my barn in case the manufacturer "change's" something or quit making it.I'm picky AH and this stuff does what it says so I am endorsing it..Good stuff!

WE USE THIS IN ALL OUR DIESEL PICK UP TRUCKS , LAST LONG AND WORKS GREAT

I really like this oil but the shipping sucks. It’s was two day shipping and late. Then today it was supposed be delivered and late again. Really frustrating but I’m sure it will eventually be here.Edit: ended up getting lost and I had to reorder it. Not the company’s fault and I still love this oil. So I changed my rating from a 4 to a 5.

Seems to do everything it claims too. The truck does seem quieter and runs smoother. Not sure about the mpg yet but will check it out on this upcoming trip.

Gotta say I'm happy with the performance of this oil, which I noticed when I first used it on my own F250 prompting me to switch all of our semi trucks on it. We used to run Rotella and Royal Purple on 8 long haul trucks. I've been using this oil in my trucks for about a year and a half, buying it from Ebay, and now happy to see is on Amazon Prime which is convenient for me.Performance: I had instant startup at -20F freezing temp after being left outside all night so great cold start performance, havent gotten that with other 15w40's, mostly used Royal purple until now but product seems to perform much better. For my truck (F250), had it analyzed at 10k and then 15k miles. Changed changed the oil at 15250 miles even through Polaris labs came back with green across the board. Additive depletion was less than 15-20% vs fresh oil, which is very good. Probably could have gone to 20 or 25k without issues but 15k miles is enough.Our highway semis regularly run 75-90k miles without a bypass filter. Started them out at 45k drain then gradually increased to current level. Oil analysis comes back green at 70k highway miles. TBN seems to stay at safe levels all the way through, without any TBN boosters. The viscosity also stays within the spec range of a 15W-40 all the way through, doesnt get thicker or thinner. This saves us additional cash as we dont need to use oil viscosity stabilizers. When we used other brands of oil, after about 30k miles the viscosity would drop and we had to use Lucas oil stabilizers to "thicken it up".High quality product, great price and highly recommended. Will keep using it.
