on my N/I 3 spd, my fuel lite starts to flicker at 300 miles.

 

My milleage per tank can fluctuate by as much as 100 miles. Depdending on how much I play with the power. But I would say the best that I will get is 350, and the worst is about 250.

 

My truck (1992, 250, club cab, auto) averages between 450 to 520 before I fill it up. I dont know if my low fuel light works because It has never come on. It usually takes 25-26 gallons at fill up. This is driving civilized, if I goof off at all she gets REAL thirsty!! My truck has a stock HX-35, 4" turbo back exhaust, hughes converter, pump turned up a bit.

 

I have a 92 w350 flatbed auto and I really have only a vague idea of the mileage around 15. My Odometer is dead so I am just guessing by tarveling a known distance and how much fuel it takes. By the way how accurate is the gas gauge in thesae trucks , i know it will vary from truck to truck , but I remember 80's chevys were prone to lie, are these similar?

 

i get 250 miles on a good week no towing just in town drivin

 

520...wow! On those 520 days, what is your calculated MPG's??

 

yeah, i actually just got home on fumes from a full tank and i was at 531 miles. Probably at least 30 miles of that was at full throttle too!

 

My low fuel light has been on for a solid day now. I am over 400 miles. I will probably do another 20 miles before I fill up. I'm kinda nervous because the next 20 miles will be in Dallas traffic, and should I run out, I will get fired upon several times by angry motorists.

 

Just as an FYI, and yes, I realize every truck is different and has their quirks, but with a fuel light on continuously for 40 minutes of freeway driving, and 450 on the odometer, my tank took 24.99 gallons to fill at that point, so do the math. 5 gallons left at 18 (average for all here, it seems)mpg, you may be OK.

 

I take that back. I do not realize how long of driving in Dallas traffic you are doing, so don't chance it!!

 

Think, stop and go 8mph lots of construction.

 

Well, I had 412 on the odo, all city traffic driving, and I put a little over 25 gallons in. I guess I should get an easy 450 per tank.

 

Its like 21-22. Thats driving around Phoenix with the AC on about 200 miles a day. So as it turns out my fuel light does work. It came on today with 532 miles on the trip. She took 24.077 gallons.

 

Well guys, I drive 110 miles a day round trip to work, 64 miles highway, about 70-75 mph, And the rest, low speed, and hauling stuff around the job site,,, Typically i get 550 miles on 23-24 gallons,,,,, My skinny pedal is no stranger to the floor!
