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 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]
