you don't use much fuel at idle,you need to keep that turbo cool ,idle is better than start stop for the turbo!

Depending how its driven (if just sputtering around, not putting a huge load on it) i would be shutting it off between stops. Give it 30sec or so for the turbo to wind down and the oil temp to drop and shut it off. no point in wasting fuel for nothing.

carful oil temp doesn't refect turbo temp. turbo can still be hotter than the pyro temp shows ,when you first stop driving good luck :thumbsup:

yes, but one of the main purposes of idling before shutdown is to allow the engine oil to cool. One more aid in avoiding coking the oil on the turbo shafts.

Manifold/pyro temp drops faster than oil temp anyways and really doesnt reflect the heat in the center section and shaft also.

Invest in a Turbo timer, BD sells one that will shut you're truck off based on EGT. and is adjustable, I think they're about $150 or so. IMO well worth the fuel savings and seeing the looks on people's faces when you're truck shuts off on it's own:hehe:
