I wasn't precise enough on earlier Q. Need instrument to measure Minutes Per Gallon of gas used while at Idle

Question

Want something to measure the minutes per gallon used in my vehicle while the car is running but not moving. Thanks

Answer 1

well i am not sure of such a device but I just got my sunday paper and in the cartalk section someone asked how much fuel is consumed while idling. here is what the answer is:

"The only statistic we've ever seen for the amount of fuel used at idle is from th Ohio Air Quality Development Authority. It says that the average car uses about 0.15 gallons of fuel per hour of idling. That's about 45 cents worth of gasoline. If you do that once a day for 250 days a year, that's $112.50 a year at $3 a gallon." if you want to see the whole article go to www.cartalk.com.

Answer 2

Run it out of gas. Add a gallon and restart. Let it run until it dies again. Or there are some "after market" systems you can buy called driving computers with a device that goes in the fuel line and measures fuel flow quantity. Spendy if you can find them. I haven't seen the around for awhile. Good luck.

Answer 3

they dont make such a thing. but i know you can let your vehicle idle for 5 minutes and it uses less gas than starting it. also you would be measuring gallons per hour not minutes. or actually hours per gallon...
