exhaust brake on/off

[chopper698]

I have read else where that keeping your EB on all the time keeps the soot off your turbo, is this true? I have an 2011 2500.

Yes, unless the road surface has poor traction (snow/ice) you should try to use the EB as much as possible.

I have run the EB on both of my trucks, 08 and 10, 100% of the time! Even in the snow and ice with out any indication of getting sideways or out of shape!

I've played with mine in the snow/ice and in 2wd it takes no time to start the process of swapping ends. In 4wd its a non-issue.

I agree with the use of an exhaust brake 100% of the time with the 6. 7L engine. I have never notice a loss of vehicle control when stopping or driving with the exhaust brake on rain/snow or icing road conditions. I live in Northern IL and we do see our share of winter and slick road conditions.



This is my opinion and I have not research this enough. But I think the aftermarket exhaust brakes may exert more braking force then the 6. 7L engine exhaust brake. This maybe were the issue is more prevalent in stopping or using the exhaust brakes on the 5. 9L engines when equipped with an aftermarket exhaust brake.

just my $0. 02

I use the EB all the time cause it sounds cool and after 79K miles I still have lots of pad left on the brakes.

I use the exhaust brake 100% also, I have noticed that in slippery conditions the EB will turn off when the rear tires loose traction.

I don't use it all the time.
Traction has not been a problem.
I will use it for cold start warm ups and apply it a couple of time each time I'm in the truck but it mostly gets used for when there is a load behind me and the road is not flat.
The rest of the time I coast into stops and hardly use the friction brakes.

I use mine all the time... winter too. In fact, the lead diesel mechanic (a friend also) at the local dealership said is was the best thing I could do for the turbo.

I have read on other forums that using the EB on the 6. 7 decreases fuel mileage. Logically, that makes zero sense to me.

However, I have noticed in the few weeks I've had my truck that I can attain better mpg with the EB off. At least in around town driving.



Any thoughts on this?

Ditto. I run my engine brake at all times.

There are a couple ways it may decrease mileage. One is it takes a lot more fuel to idle with the brake on, second if you used to coast to a stop and now EB to a stop you are driving more and coasting less.

... One is it takes a lot more fuel to idle with the brake on, ...

The exhuast brake turns off when <5 mph, so, unless the engine is still cold, it should be off at idle.

 

[Hoefler]

When the exhaust brake is activated and the engine speed is above idle, the injectors are using less fuel than it would when the exhaust brake is off at the same road speed.

Correct

When the exhaust brake is activated and the engine speed is above idle, the injectors are using less fuel than it would when the exhaust brake is off at the same road speed.

Not necessarilly true. If the throttle is zero and the rpms are above idle the fuel injected is zero, regardless of EB actuation.

Very true.
