2018 Cummins Engine Brake

While an exhaust brake will certainly save the brakes, keep in mind that just the rear tires are doing all the braking work and wear will increase, especially while towing heavy.

The auto mode down shifts too much for me, so I use full with tow hall most of the time.

I start engine, push TH and EB FULL and drive with a smile on my face towing or not!

Front pads at 55k. Rotor and pad still looks new.

I personally do not like the auto mode, and run the full mode all the time. In auto mode and cruise control, truck will gain about 4 mph before the exhaust brake engages. In full mode I control exhaust braking with my right foot, on or off the throttle pedal. I tow pretty heavy for a SRW (3500) at a combined weight of 24,500 pounds. Descending a mountain grade I manually select the gear I what be control my desired speed via the EB.

As noted, use of it all the time saves service brakes. Just be aware that the person behind you does not seen brake lights.

I believe that certain high trim level Ford's with adaptive cruise control use the service brakes in conjunction with the EB when in the auto mode.

The few times I use mine unloaded is when I am getting off the highway especially if the off ramp is as short as the one on my way to work. I will say that auto mode was better after my truck was tuned than before due to the shift points and the fact that it stays in whatever mode you last had it in even when you turn off the truck.

I hope he likes his new truck. It doesn't really matter to me how people use their truck or whether they actually need it for its purpose. Whether it is a sports car that never sees the track, an off road vehicle that never leaves the pavement, or a 4 door car that never carries more than two people. It is their money to buy what they choose and it helps the economy.

Leave it on all the time? It saves on service brakes.
BTW its not an engine brake, rather it is an exhaust brake.
Sad to waste such a nice tow vehicle as a grocery getter.

I don't. I'm sure his owner's manual will address this.
