C15 Cat and ISX Cummins
I am trading my truck in for a newer one. I am tired of my Detroit series 60. Which of the 2 engines would you prefer?And why? What are your experiences with each one?Good and Bad? What kind of fuel mileage have you gotten with these engines at speeds of 85 to 100mph?

You must have some really tight delivery schedules. Is it mostly city work as well? :D

Last 2 motors were C-15's. I get about 5.3 at excessive speeds, and 5.8 at normal speeds. Happy overall with performance. I have never owned a Detroit though, so I can't comment on them.

Okay Triple Digit, I'll try to help you out with my first post on here.
I've driven a lot of Cummins that I liked and only one Cat that I liked--it was a 550hp. It seems like the other Cats I drove, that were below 500hp, couldn't keep up with a Cummins. I say stick with the Cummins. I am curious to hear about the new International 600hp engine, I kinda think that thing might be hoss. Sounds like you may be making some of those Western reefer runs at the speeds your running. I used to love running out to LA from home (New Orleans). I-10 will make you love a fast truck. |
The company that i work for has all 475 and 550 cats that run pretty good .My boss just got a good deal on a 06 pete with the 565 cummins .When we are on a hill the cummins just walks away from the 550 cats .I have to admit the cummins runs better than the cats we have.I cant comment on fuel millage because we do all heavy haul in excess of 120,000 lbs.and the fuel millage on both motors are bad.

I have only owned & driven a detroit. the m.p.g has always been great. power? not on my 11.1-350 h.p. but I'll take slower & better m.p.g. anyday. I think more det ser 60 go to a mil miles more than cat's or cummins, though i could be wrong.

85 - 100 ROTF.
Anyway, FWIW.; 2008 ISX 485 HP in a T660: 5.0 mpg grossing 80,000. Truck is governed at 72 mph. 2005 C15 Acert 475 HP in a T2000: 4.5 mpg grossing 35,000 - 80,000. Driver recently got a ticket for 80 mph. |
