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'm will be looking for a car soon. A USED car, as I simply can not afford a new hybrid or anything like that. I have heard of TDI Jettas being as few efficient as Prius's. I am aware that diesel is not so awesome environmentally. But I want to know if it evens out. I'm looking for links to reputable information on the topic. NOT - opinion of hear say. If you know enough to talk my ear off about it then you know where to find the information, then do so and send me a well resourced link to back it up. [more inside]

There is a good chance that I will be the owner of a new car sometime soon (like the next few months or so). Looking for a good balance between fuel efficiency and inexpensive to repair (something I have not really thought about until recently, regrettably). You are not a car expert, likely, but what would you advise from what you know? Details, including what this car replaces, inside. [more inside]
A few weeks ago I asked this question. Consider this a follow-up question. I have a 1993 Honda del Sol 5-speed Si that has a "mystery" problem of sometimes starting and sometimes not starting. It's always a cold-start problem. I put the key in the ignition, switch it to ON until the check engine light goes on, the fuel pump pressurizes, and the main relay clicks, and then crank it. Sometimes it will fire up right away. Other times the engine will turn over but not ignite. Once it is started, it will start up fine for the rest of the day. It only gives me trouble when the engine has gone completely cold and has been left untouched for upwards of four hours. A new issue has developed since I first posted my question. Even after getting the car started, sometimes just a few minutes later during a sharp acceleration (approaching 4000rpms or more) the engine stalls out. I have to pull the car over and start it up again. It always starts up fine after that and will usually not stall out again. I had this issue looked at by several mechanics, most of whom hadn't the slightest clue what it was or willingness to investigate. The last mechanic I took it to said it was a faulty ignition switch and replaced it . . . but that has done no good whatsoever. Also, just FYI, the spark plugs are relatively new. Any thoughts are appreciated!
My wife and I both have iPhones. We also own two cars. We each drive either of the cars, depending on where we are going and how many kids we're taking. Is there an app that lets us sync fuel records for both cars between both phones, no matter who does the fill-up? How do we synchronize our records?

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.

When I gas up my car, I don't squeeze the lever on the pump handle, but, instead, I slide the lever into the little notch so that my tank will fill itself up while I squeegee the windows. When the tank is full, the pump shudders, the lever dislodges itself, and the filling ceases. However, probably half of the time, the filling ceases much, much too early. The result is that I can't tell when my tank is full, nor can I squeegee while my car fuels itself. What gives? [more inside]
