And leaving a tractor tank at 1/4 to 1/2 full can lead to water condensing in the tank, causing a different problem. It's nothing more than good manners to not characterize people who do not do what I do as stupidity.
I was assuming IN USE diesels, one could argue that it is irrelevant for out of use machinery.
There seems to be a belief that a near empty tank somehow SUCKS IN more volume of wet air than the volume of fuel consumed and that there is a meaningful difference between the 1/4 to 1/2 and the 3/4 to full ranges.
I have always had difficulty with that, perhaps you can help.
Is it due to daily thermal cycling ?
Is this only for machines left idle for MONTHS ?
Is it significant ?
Modern diesels have water separators and in many cases indicator lights to show when they need to be drained.
I don't drain mine as often as the owner's manuals suggest, though once every year or two keeps the light from coming on.
Again, these are IN USE diesels.
A little planning, a little forethought,,, lets not get into whether or not lack of planning and/or lack of forethought constitutes stupidity ?
I argue that lack of either can be fatal.
