The new Volts have a "hold" mode where they will hold on to their current charge and just use the gas engine. I'm sure I can run it out of gas and then have 40-50 miles to hit a gas station on a long trip (No reason to use the charge first). Is this "Bad" for the gas engine?
I'm asking this because I remember people telling me that it's typically bad to run a "Normal" car out of gas because it sucks up junk at the bottom of the gas tank that is best just left alone (Clogs gas filter/injectors).
So is it bad to run it out of gas, or perhaps good because it will stop "Sludge" from accumulating--or is the whole thing a non-issue unless your car is like 20 years old?
