Re: Fuel Tank Only Filling up to 7/8
Two thoughts on this issue:
1) Shame on them in the first place for intentionally hobbling these cars with a 13 gallon tank. WTH? I've ordered a Malibu Hybrid to replace my current "highway car", which has a 14.5 gallon tank and reliably goes well over 700 miles on a tank. This is an invaluable characteristic in a car used mainly for road trips. The Malibu is a nicer, more comfortable car than the one it's replacing, so the only thing that will be holding it back will be that silly 13 gallon tank. I guess there's just no such thing as the perfect car, even for this one specialized purpose...
2) If GM is going to insist that 2 gallons of fuel must remain in the tank for pump cooling (or whatever) purposes, then they should not be counting that fuel as part of the usable capacity when they specify the size of the tank. Frankly, I don't believe running the tank completely out of fuel once or twice in the car's lifetime (typical occurrences) would appreciably shorten the pump's existence anyway, unlike the HPFP in my Diesel...which needs constant lubrication with its unbelievably tight clearances. In any gas vehicle when the engine is running, and it then runs out of fuel (stops running), power to the fuel pump is cut automatically. The fuel pump will only have been sputtering at part load for a matter of a few seconds...probably not enough time for it to incur any damage, let alone overheat. So, if my Malibu exhibits this type of behavior when I get it, I'll probably put a 1 gallon can of fuel in the trunk and then run it all the way out...once...just so I'll know the tank's true capacity...because having that accurate knowledge can be an actual safety issue.
