Paccar MX 500

I have 360K on mine running a dedicated run engine has been trouble free except in the beginning as any new trk has teething problems. I have a tri pac so i do not idle very much. have dpf filter cleaned every 200k and initial overhead done at 40k. Engine does not use any oil between services at 30k. recommended at 40k but i run at gross 99% of the time and i run the engine pretty hard. So i change a little more often. One recommendation is use the Paccar filters and not the fleetguard filters, especially fuel filter. Lifetime fuel mileage is 6.6 mpg. It is in a t660 with studio with a 18speed. Very happy with engine,not my beloved cat engine but does a fairly good job

 

mine is a 2013 trk, and yes you'll be disapointed in any engine after driving the Cat's. so get use to it

 

Hi, I have a 2014 pete 579 with a paccar 500 in it, a 13 converter and 3.23 sprocket.
My truck is really smooth, I'm avg 7.2 miles to the gallon pulling a skateboard and some full weight here and light there..
I've had 0 problems, 0 down time and 0 lack of power coming from that 15.2 ltr Cat @ 475.
I like the sound like detroit when you first step on the throttle, but then like a Cat once you're 70mph.
0 oil consumption, 0 coolant consumption either, I'd recommend this engine and a good warranty for the whole truck.

 

As long as you do maintenance in time. If you hear maintenance free, they want you come to shop daily.

 

What speeds are you running and what part of the country do you run?

 

Yes you'll be terribly disappointed unless you go with the cummins.

 

im now running a cummins 550 & so far been good > do mostly const work , end dump & bottom dump , flatbed.
not like the cats ive had , but doing good so far
