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?

My friend needs fuel for a Crate & Barrel's Culinary Torch, SKU 447463
The torch was purchased at Crate & Barrel, fuel not included, so:
What kind of fuel should we get? We've heard propane. Is that correct, or should it be something else? And what sort of container does it need to be in?
Finally, where to buy it?

I know a couple of folks with gas stoves, and they have trouble with a sticky residue coating their walls and ceiling around the range. They describe it as inherent to cooking with gas. (It's really disgusting.) Yet other folks I know who cook with gas don't report any such problems. Is this a known problem? Any idea why it would affect some people, but not others? Different types of gas (natural vs. propane)? Badly-tuned stoves? Something they're cooking? [more inside]

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]
