I have had my x15 605 hp 2050 torque for 2 years now and the only problem I've had was the egr coolant went out at 80,000 miles. Truck now has 330,000 miles on it now and still all good 👍

Steve- (Greatest Salesman ever)... Purchased mine about 6 months ago from you, zero issues. My local Cummins dealer is providing routine maintenance/service, and with the exception of a little fuel mileage loss after the first software update, I am completely satisfied. Pulling flats in the mountains of Kentucky and West Virginia, our’s gets a real work out, but with the 2050 torque we handle the grades with stride, while delivering a solid 6 MPG. Yeah, we sacrifice a little mileage running a big hood 389, but looks and appearance are quite important to us, as our family has always had long hoods since the 90’s. Such praise coming from a Caterpillar lifer, should speak volumes. Keep up the good work!

2050 torque has it's advantages but it will grind your rears all to pieces if you get stuck somewhere and start spinning your wheels to try to regain traction and free yourself... So a lot of, especially heavy haul, operations turn their 2050s back to about 1900 for driveline component safety.

I'm glad Cummins has stepped up with the x15 because the isx is pure junk if the x15 is anything like the old big cams or the n14 they have a great engine again.

Mine was great until 218k now the parts throwing at it started hopefully it holds together now.

I have 2019 western star with x15..210K miles...its at Cummins getting an injector and my cam is shot...Cummins has apparently designed a new one to replace these cams when they wear out...just letting y'all know..

Question, I just bought a 2016 579 with a 2350 cummins 450hp, and I have all the paperwork for all repairs, the oil has been changed every 15 k miles, my question is do I stay with 15 k or go to 10k? Shops are telling me mixed opinions?

The best modification that you can do is have a proper MINDSET. Drive a truck the way a truck is suppose to be driven. Nobody is pointing a gun to your head and tells you that you need to have big power plant under the hood to outrun and outpower the rest of the trucks out there.

@@rowmacg It's doing really well. So far it's mostly in firetrucks, cement mixers, large Freightliner dump trucks and coach buses, but it will be in the Freightliner day cabs this year. So far people are liking it and is proving to be reliable. Cummins put a lot of time and money into developing it so they can get back into the midbore market. Other OEMs as of right now aren't putting it in their chassis yet due to it being additional competition to the midbore engines they make themselves.

From my experience my x15 has 288k miles on it and I have not had any issues with the emission side of it. Now I did have camshaft issues at 213k. Had to be replaced. Ran my mx13 till 456k. Had check engine light on every over week. Blow head gasket at 359k two injectors went out. 9 nox sensor over 3years I've had it.

In the past one year Oct '19 and Oct '20 I've run two X15 engines and while I like them a lot and have had no issues with them, I don't understand the banging / slapping / clanging noises these engines make especially when you get into the throttle, the louder they get. While the engines sound like they are about to spill their guts all over the highway, after a while I've learned to ignore the noise and run. I've never heard a H-D diesel make that sound before and I wish Cummins would at least educate us as to what the noise is and what effect it has on the engine if any. The noise emanates from the drivers side of engine and sounds exactly like steel smacking steel. At 125k miles, it starts hard and slow and shutdown occurs in less than 2-seconds flat which is kind of frightening but again, just ignore it and go about business. It's a great running engine, just has a few quirks that take some getting used to. All the X15 engines do it, just don't understand it.
