X15

565x2050 performance

 

Performance or Efficiency? Read a lot of threads on here about the Efficiency being pretty gutless even when rated at its max. Heard they have head gasket issues due to running a high compression ratio than the Performance.

 

the 605 and one of the lesser powered models is listed as “productivity” I am curious as to the differentiation?
* Excuse me it was actually more than one of the lesser horsepower models

 

Nice pick… I’ve got an x15 565 performance w 1850 .2020 year , 20,000 miles automatic transmission
I wish I got the 2050 torque but other That , truck runs great

 

The Reason I got 1850 Torque was because sales guy said gas mileage would be better than the 2050 …. Is there any truth to that?

 

5.5-5.7 mpg 71 mpg is most I usually go Midwest, northern plains, and western states. I run heavy. 3.25 rear and 18 speed.

 

I enjoy my time diving one no real problem for me ran it hard and Long but did fine. It did run a little hotter then I'm use to and have to add oil ever now and again. My company did have one where the wire harness caught on fire though it was a 18

 

1850 here. 18spd 4.10 rear. Hauls 80k everywhere thru Las Vegas gets an average 5.0-5.2 gpm. For a local dump truck I’ll take it. She’s not much on the road speed area that I’d like her to be, but she moves her weight with ease.
