Does anyone know what the 4.0 V6 uses for fuel to start/idle, and does anyone actually do this?
Keep in mind that your power brakes/steering shut off too! This is VERY unsafe and I have seen lotsa sites & threads that say intermittantly (sp)coasting on the freeway can save you a ton of money but so can driving 55 or skipping the drive thru or keeping your tires inflated properly. I would rather people steal gas that coast on the freeway and put peoples lives in danger.
*****as chris steps down from his soapbox*****
but to answer your question I don't know how much energy is used at startup/idle....sorry!
