How can I get this diesel to start? I have a 1996 Vandura van with a 6.5L diesel motor. I stored it all winter...and with a quick jump it started. I drove it around and it did fine, but then right before I got it home it died. Now it won't start. What am I doing wrong? Do I need to add something to the fuel? The batteries are fine and it cranks, but won't turn over.

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?

OK, I know this is a little silly but it's really beginning to bug me. Is there a way to get the nozzle from a commercial gasoline dispenser out of my car without spilling a few drops of gasoline onto the car or the ground? I have tried shaking the nozzle every which way, i have tried fiddling with the hose, but nothing seems to work. Is spilling a little gas every time I fill up a law of nature, or am I missing something that everyone else knows somehow?

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?

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]
