No Idling

if your going to be stopped and idling for more then 15 sec turn the vehicle off (applies to newer vehicles with fuel injection) the whole "takes more gas to start a car then it does to leave it running" died when all the bugs was worked out of fuel injection. modern fuel injected cars uses lil to no more gas to start it then 15 secs of idle when warmed to op temp. (i have done this and do it at times i had picked up bout 4ish mpg) provided by W.H.
