i have a JD diesel utility tractor no glow plugs and if it is 40 degrees or lower starting it is a no go i have to plug it in for a hour to warm up the engine which is no biggie to me, it has a in line heater on the radiator lower line and after 1 hour of being plugged in engine block is warm and starts easy.
one thing i have heard is that you do not want to use either to start them repeatedly, after a while the engine will become addicted to it and not want to start with out it. mine has an either injection system on it but i never use it.
as to fuel i filled up in end of April and am still on the same tank of fuel
just more to think on
