My car weighs 4013lbs (with me in it) and averages 17mpg on my 21.7m (roundtrip) commute.
My gas tank holds 20 gallons, but I only ever fill it up half-full. The reason I do this, is because my brain knows how heavy 4 x 2.5 gallon containers of water
is, and thinks that not carrying this additional approx 60lbs of weight (1.5% of the 4013lbs) will be better for both mpg and performance (i.e. less liquid sloshing around the tank). Is my brain crazy?

Help us pick a car! We're looking for a good used family car. We have two daughters, a 2 1/2 year old and a newborn and need a car that can accommodate an infant car carrier without putting the front passenger's knees in the glovebox. [more inside]

My car, which is rarely driven, is unexpectedly acting like it's full of gas and will not accept more. I have no recollection of filling it with gas, though I do recall that the last time I drove it, it was hope-i-make-it-home almost empty. Am I just super forgetful? Or is there another explanation?

My friend says the fuel injection in my 2002 Jetta wagon (non-diesel) suffers if I let the tank get less than 1/4 full. She also believes that "el cheapo" gasoline, from locally-owned non-chain stations, isn't as good, or is actively bad, for the car. Is there any truth to either of these claims?

In three cars I've driven, I get about 300 miles per tank of gas. But with all three cars, I can get up to 200 miles by the time I hit 1/2 tank. But invariably, by the time I near the 300 mile mark, I'm on E. Am I nuts or do gas seem to burn faster in the lower 1/2 of my tank? Is this mental or by design? [more inside]

GasFilter: How do I learn more about the quality of various gasoline brands? Also, how can I determine who supplies
gasoline to a particular retailer? For example, is Speedway gasoline really the same as Sunoco gasoline (since Sunoco purchased them), or do they still use their own gas? How about the gas at my local Sam's club, or Jewel-Osco -- who supplies that gas to them?

Why hasn't solar energy been able to replace fossil fuels in Europe where gas is taxed so heavily?

Sitting in a car today as my friend was filling her tank, and my colleagues and I wondered aloud why there doesn't seem to be a standard for which side of the car has the gas cap on it. The car we were in had it on the right, as do both my cars, but the others in the car had cars with the caps on the left. What logic do car manufacturers use to determine from which side fuel is delivered? Some vehicles have the delivery point at the rear, and I believe I once saw a car with the gas cap near the front somewhere. Anyone know a rough ratio of left / right on North American cars? If there is a majority, is it an ergonomics thing? Just curious.
