I have one of those cherry red gasoline jugs that I use to store gas for my lawnmower. Usually I just re-use the gas from year to year, but I know that's bad (OLD GAS!), and I'm trying to take better care of my mower and do things like use new gas and change the oil and, you know, stuff, so I'd like to get rid of it and get some new gas...

This is just a thought experiment at this point, and probably will remain so. In the back of my mind I have the idea that when my old SUV finally gives up the ghost I might rip out the internal combustion drivetrain and convert it to an electric vehicle, possibly with a removable range-extender generator. Setting practicality aside for the moment, can you help me envision what this would involve? [more inside]
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?
I've become mildly obsessed with trying to improve the fuel efficiency of my old truck. I've already done all the basic things and I realize that I'm fighting physics at this point, but what else might I consider if I wanted to make a bit of a hobby out of it? [more inside]

Simple tricks to improve MPG? For instance, I've thought about removing the rear seats/internal molding to lighten my car. I've also thought about aero-improvements, such as moon-disc wheel covers, or even somehow making a cover over my rear wheel wells. I'll be removing my rear wing this weekend, but what other tweaks could I do? [more inside]
Bad Gas, the car kind, I think - advice? [more inside]
Is it true that it is good for a car to fill it up with higher grade gas once in a while? I usually fill up at Shell, and there is 87, 89 and 91 kinds of gas, with 87 being the cheapeast and 91 being the most expensive. I usually get 87. However, I heard that if you own a car and want it to last longer, it is beneficial to fill it up with the most expensive gas, to "clean the engine". Is that true? If so, what is the explanation behind it? I drive a 2002 Kia Rio, if that makes any difference.

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.
