With Summer coming.
I'll have many days I don't need to drive my truck.
I can ride a bike to work.
Saving fuel and money. My question is.
How long is too long to let it sit without driving.
I know this may be more opinion but I realize that.
If I could have some persons chime in with their opinion supported with some nice facts I would love that.

Mine has sat for two weeks when I have been out of town, and it cranked like I drove it the day before:Thumbup: . I wouldn't think you would have a problem unless you left it for months on end. See ya:popcorn:

I would try to drive it at least once every 10 days or so to keep the battery up and more importantly the water out of the oil (condensation).

Perfect answers from both, thank you very much.

Also I wanted to ask you veterans.............
My cummins seems get tons quieter as it gets warm.
Is this natural?

Yeppers, the timing backs down plus the fuel warms up as well as the motor, perfectly normal.
