Half a croissant, on a plate, with a sign in front of it saying '50c'

Fuel Gauge-->Money Gauge

Watch your money disappear right before your eyes!

I have a debit card. As a result, I spend money and don’t record it. Often.

Not that I spend more than I have. I just find stupid things on ebay that for some reason I feel I need. I diverge.

Anyway, my biggest expense comes at the pump. I swipe my card so I don’t have to go in to pay, which is great, but I never know how much I’ll have to pay for a fill up.

I want a system that supplements the fuel gauge with a digital display of the dollar (whatever currency) value of what’s left in my car, and how much it would cost (at the previous rate) to fill ‘er up again. Not only would I be more likely to take note of it for my own records, but I would watch my dollars burn away and make a better attempt to be fuel efficient.

Don't EXPECT it -- but a very novel idea. My $.50 croissant is yours ... [+]
  

       It would have to somehow be updated with the ever changing prices of fuel, though. Perhaps some daily update via bluetooth at the pump is in order ...

       + for the simple fact that it might make people think a little more about the costs of the fuel they use.   

       Would be much improved if the $/£ showed the true cost to the environment, rather than simple cost at the pump.

       Also, as you cross state lines from New York into New Jersey, the $ amount would change to reflect different prices. Cute.

       Croissant from me. The problem, of course, is that the fuel gage is not very accurate. You would have to create a gague that determined how much gas was in the tank to the 1/200th of a gallon (assuming gas doesn't top $2.00 a gallon anytime soon) to get a gague that calculated to the penny. And you would have to do it without electrical parts. One electrical short inside a gas tank, and the whole world will see you running from Morely Safer, Stone Phillips, et al...

       [dbsousa] you are making things unessesarily complicated, they already have gauges that tell you in liters how much you have left, just multiply that by the current gas price ( which could be entered manually).   

       Anyways [YDYD] isn't lauching a rocket here where acurate fuel amounts are critical, this is just a novelty.
SystemAdmin, Jan 29 2004
  

       Brilliant! Croissant for you.

       You just praised yourself?   

       I like this idea, I drive way too fast... Maybe my blow off valve will start making a "chii-chingg" sound........
KLRico, Jan 29 2004
  

       Your blow-off valve ... lets not go bragging here, 'Rico ...
Letsbuildafort, Jan 29 2004
  

       Hehe, Sorry.... I just HAD to thow that one in there ;-)
KLRico, Jan 29 2004
  

       I praised the recognition of simplicity here. Come on, now.

       This is quite an amusing idea, an integrated system could have some kind of Bluetooth fuel price updating dooberry as someone mentioned.   

       [dbsousa] I think most people would be happy with a gauge that was accurate to the nearest half dollar/pound/euro/whatever and stop stressing about gas prices; try driving in the UK, petrol works out to $5.80/US gallon over here.

       Works for me. For those with fancy trip computers, they could also display the current cost per mile and cost per minute, taking into accout the price at which you bought the fuel and the way you're currently driving.

       Auto PC systems abound.
bristolz, Apr 28 2005
  

       [st3f]Cost/mile & cost/min would actually be easier than cash remaining in fuel tank; many modern cars can give you an instantaneous mpg reading using data from the engine computer.

       Directions to wedding:
Get on Rte 87 North
Drive $4.50 to Exit 16
Main St $2.55 until McDonalds on the left
Turn left and church is $0.75 down Cedar Rd.
phundug, Apr 29 2005
  

       Calculated by speed limits along those routes.
bristolz, Apr 29 2005
  

       And, of course, the fuel consumption of the directee's vehicle.
squigbobble, May 02 2005
  

       You get a biscuit because I've thought of it, too.   

       (I doubt if I could ever get to all of the ideas on here I've independently come up with, though, so it may not be fair...)   

       I also like it because it's one of those things a garage tinkerer could cobble together himself (with manual price/unit entry).

       How would currency conversion work when driving across country borders? Could it be tied to the mph/kph switch somehow? (Rant: I am still upset my temperature readings do not switch to Celsius when I put my gauges in kph mode).
ed, Oct 17 2007
  

       Cool.   

       There's a few pumps around here that can read a transponder keyfob for credit sales; it may not be a big deal to get the car to talk to the pump and find out how much fuel was taken on, and at what price. Instant fuel mileage readouts already exist; that easily is translated to dollar mileage. (+)

       [SystemAdmin] - Great username.
wagster, Oct 17 2007
  

       I would love to have a gague directly on the card itself so as I am frivilously spending all over town, I would have a visual display of how much money I have left.
Jscotty, Oct 17 2007
  

       Buy an old taxi and flip the meter on?
popbottle, Oct 22 2013
  

       Much more polite than flipping the meter off (+).
