Exhaust brake / tow haul combo...

I find that running the diesel exhaust brake and the tow haul concurrently gives me a really nice firm down shift and quick deceleration. Does anybody know if this costs in terms of fuel economy?
 
Tow/Haul is going to change shift points to higher RPM's for more power resulting in lower fuel economy. The exhaust break when active shouldn't be consuming any fuel (or at least minimal fuel).

Much obliged sir.
 
The exhaust brake will have a slight impact on fuel mileage since the vehicle will start slowing more quickly instead of coasting. However it does save brakes and is a good thing for the turbo charger. At the end of the day do what you feel comfortable with and don’t worry about a slight decrease in fuel mileage since these trucks are not exactly economy models. Enjoy it.

Beautiful pups, I grew up in England right at the border of Scotland, they were bred there for farmers, very agile and very hard working dogs, they cost tens of thousands trained for farmers. They are also "a**holes" to other dogs because of their jobs lol. I loved working on farms in the summer and working with them.

On your original subject, pretty much echoing the same statements, it feels and sounds nicer, you don't coast as well, light footed you wont see any difference.

Sound like you led a charmed life sir. :cool:

On the fuel efficiency/throttle thing I'm gonna give it a try and see what happens.
 
I have tested TH vs no TH to/from work and on my commute it cost me exactly 1 mpg. 16 miles on-way, mostly rural with speed limits up to 50, 4 stop signs and 1 light.

I haven't noticed a difference with the EB, but I also use Auto around town so I can coast when wanted.

I'm ok with a MPG cost to use the TH mode... I'm thinking brake life extension.
 
At $5.00/gal and 17 vs 16 mpg the cost difference is roughly $0.0184/mile. That's just TH, TH/EB will have a bigger impact in the full mode.

If the brakes last more than 15K miles more then you have paid more for the fuel than the savings on the brake pads.

Even in TH the EB isn't as effective at saving the brake like it was on my 05 with a NV5600. I figure the fuel economy is a better cost savings over time when bobtail.
 
ill use both when its time to stop, but always have the exhaust brake on full mode.
still factory brakes with 45K on her already, 75% is highway from Ohio to tx, Nola, ms, fl (4x in 1 summer) and va
