Idle Time and other Numbers

[MullenaxM]

Although Idle time is Important , In my opinion there is another number, as a owner, I would be more interested in. Also as a Technician it is one of the data parameters than I look at to help with my diagnosis of trucks with issues with the aftertreatment systems.

I look at this number in my area and have formulated a base line and average for this number.

If I could get Ya'lls help (sorry, remember I'm in Texas) I would like to try something. I think this will help me as well as give you another tool to help with understanding the 6.7 liter diesel and in my opinion give you data parameter that you can use.

First, Go out to your Truck and get in and turn the key to the Run position (don't start the engine), Next make sure your odometer is reading the mileage and is not on the trip meter. With the odometer reading mileage and the key in the run position, press and hold the trip meter button in, hold it in until the mileage numbers change ( It will take about 10 to 20 seconds for the numbers to change). When the numbers change you can release the button.

On a piece of paper record the number that displays on the odometer,this is the engine run time in hours, then push the trip meter button one more time, the mileage should be displayed. Record the mileage on the piece of paper.

Next, go back in the house and get a calculator. enter the mileage and then divide it by the other number.

When you get done come back here and post the answer. You'll probably end up with a number like : 36.430834. Just post the whole number and the tenths,(ie: 36.4).

Some of you may already know what this number means.
