Coasting trucks, what's the point??

A friend of mine used one of those mechanics; his brand-new company glider truck was flying after the tune-up, albeit excessive black smoke coming out of his stacks. Needless to say that he didn't have a job the next week after the engine went kaput. I've had a similar issue when a shop (not a dealer) did an overhaul on my truck; the engine had a micro-crack on the head before and after the repair. And that is after I paid for a different head. Now I have a principle - the only repairs will be done by the dealer with a warranty; otherwise - new equipment purchase.

 

The mechanics I use are mechanics.
One used to work at Freightliner, certified on Dd13 and DD15 engines.

other came for KW, he’s good on cummins and paccar
He turned up the cummins engine 6-7 years ago, still running today.

 

The mechanic I’ve used came from Cummins dealer; the shop owner had to pay for his brand new Corvette somehow. I guess they never pressure tested the head they were installing; I was new in business so I got screwed. And here is a lesson for all newbies out there - you get what you pay for in trucking just like anywhere else!

 

I bought them brand new.

 

On the F150 its easy to override the stop/start . Google is your friend. I have a 2019 F150. Took me about 15 seconds to disable.

 

It's unnecessary wear and tear on the starter, flywheel, oil pump, ect. ... Which in the long run will cost you more than the fuel savings the start/stop gained you.

 

There's only a few places in the country that I think coasting might save you fuel... In gear or out of gear. One that comes to mind is I-80 East bound from Sherman summit (by the Lincoln statue) to Cheyenne. I'm governed at 67 and I can maintain between 70 and 80 over that entire stretch.

 

A couple of years ago when I was driving for someone in a governed truck it had this feature. Even taking off cruise control on steep down grades if I went too fast or even just trying to slow down manually it would slam into a slower gear. It was a kw with an Eaton auto.

On a side note we have our own truck now, it is a Volvo, but we had them put the governor up to 75. It has helped to keep me getting into trouble.
