I'm sure all the know it all/smart allecs are gonna take off and run with this one. But it is a seriuos question for a pretty seriuos problem I have.

The car is a 94 GT 5.0 with a stock T-5 tranny,with ported and polished gt40 aluminum heads, ported and polished cobra intake, 3:73 gears, 24lb injectors, 190lph fuel pump, k&n filter, underdrive pulleys a few other little mods.

My odometer or trip meter do not work and I would really like to get a pretty good idea at my gas mileage on the highway. I am driving from Jacksonville, FL to Baltimore, MD and I am on a very limited budget. It is a 750 mile trip and am concerned how much it will cost.

My plan to find out is to run my car until I run out of gas then have 2 1 gallon gas containers. After I run out of gas I will put 1 gallon in the tank and hit US1 at 70 mph until I run out then fill it up again, go back home get onto mapquest estamate the distanse traveled and theres my anwer. But I was seeing if anyone has any advise or would like to know the outcome of this little project.

Thanks A lot

 

your gonna need 4 tanks

 

Does the speedo work?

 

why dont you just get a buddy to help that has a good odometer. fill up with gas, follow your friend for a while, fill up with gas again and use the mileage from his odometer and the amount of gas you used and do the math.

 

+1... Not a good idea to purpously run your car out of gas.

 

Why don't you just buy the damn plastic gear to fix the odometer and not have to worry about it ???
