So Last time I ran out of gas and know exactly how many miles I can ge before engine dies. I wasn't really driving concervetevely and was going 80-85mph mostly.

I think I got about 360 miles on a tank, but don't recall

Today I have 410 miles to go, I'll try to go about 70mph and see how close to 400 I can get. Once I have 0 miles to E then I know I can go 15 more miles and should start looking for a gas station

Any guesses on how far the 5.0 can go?

With a gt500 spoiler and airaid intake just added. And3.73 gears, so that's slightly a bad thing if I'm trying to save gas lol

 

If you were to accelerate and lay off the gas IE COAST and draft 18 wheelers, I'll bet you could et up to 1/3+ more than the average mpg ratings from Ford for your vehicle. Thing is; no Boss 302 owner in their right mind is going to drive like that.

 

By extreme coasting tactics one way heading into work on a 60+ mile commute I was able to get over 28 mpg out of the 5.0. I did not try the return trip to average out the test, the hills and such would surely even out the MPG to a lot closer to the advertised 26 mph highway figure. But if you granny shift the car and coast a lot you can do quite well.

 

^ do this and you'll make it the whole way

 

"Where's the needle?"
"Oh, it broke off baby!"

 

Road trip down to VA from South Jersey. I forget exactly how much, but it was alittle over 500 miles on a single tank. Avg. was almost 35 mpg with the AC running and going around 74 mph. Low fuel light came on before we found a station.

Base model 2012 V6 auto w/ the 2.73(?) gears.

 

Sorry, just saw the '5.0' part of it.. disregard the previous post, I need more coffee.

 

I was reading in dis-belief and then saw the last part you added and was like "oh well thats why".

lol

 

I've driven mine about 14,000 miles so far and kept track of mileage religiously, with the best mileage on any tank being just under 28 (all highway, 70-80 MPH speed, no A/C). So, based on that, I wouldn't push a tank much past 375 miles, based on 28 MPG x 14 gallon tank = 392 miles.

Though I remain perplexed why the owner's manual says our cars have a 16 gallon tank but mine always tells me I'm out at right around 14. Is the warning light in our cars so conservative that it's programmed to always have 2 gallons of gas in reserve?

 

Tank is 16-gal, warning comes one when you have an est. 50-miles remaining based on your trip computer's current average mpg, not necessarily at the 14-gallon mark.

I've driven mine down to about 15-miles to Empty, and I put 15.1 gallons of fuel back in.

 

Also, you can never get 16 gallons into a 16 gallon tank.

 

I recall seeing pics from someone on these forums putting 16.1 gallons into their S197.

 

My 5.0 gave 30mpg from San Antonio to dallas, did not go over 65mph though

 

Huh what?

 

I've never been able to get what a tank is listed as actually into a tank.. if it's a 5 gallon can, it never holds 5 gallons.. same was true with my truck and any other vehicle I've had. Guess it's just me.

 

I can't wait to read your results. I think you can get 400. Check tire pressure before you go. Best of Luck!

 

Wait for the foam to die down.

 

776.5 miles is the record.

Done at Bristol Motor Speedway at precisely 43.9mph. That's 48.5 mpg.

 

Never been that important.

The computer estimates your remaing distance to 2 gallons of fuel left based on your average mpg. 50 miles left does not mean you will go 50 miles if you're on the throttle a lot.

In general, if you are driving at the exact same fuel usage as your average, then "Empty" will leave you with 2 gallons of fuel in the tank. I have personally driven mine 25 miles beyond "Empty" on one occassion, and only put 15 gallons back in it to fill it.

The computer is nothing more than an educated guess. It should not be considered accurate. When it says it's at empty you should look for a gas station, and that's all that really matters.
