Hello,
I'm considering buying a new toy and it happens to be an f-350. It's a '99, 7.3, single cab and looks really nice. It has a 10'' lift and 46'' Goodyear MVT's. I know that by no means is this truck going to be exactly sipping on the diesel. But I called the seller and asked about the mpg. He told me that he took a 250 mile trip on a half tank, along with a full size trailer that had a jeep on it. Half a tank would be 19 gal, so that comes out to about 13.2 mpg. 46'' tires, AND a full size trailer with a vehicle, that seems almost impossible to me. He does have a programmer type thing (I don't remember what brand or anything) with 12 settings and he says he keeps it on the 4th setting for fuel economy. I don't know if that will help you all out or not, but I thought I'd mention it. He also has lots of upgrades, gears, intake, etc etc, that could possibly help with fuel. But that number for mpg still seems kind of high. Or is it really possible with the right upgrades?
It's certainly possible depending on how hard you run it. These trucks can potentially see upwards of 25 mpg. Everyone Seems a little bit different though.
But did you see where I mentioned that the truck has 46" Goodyear MVT's? Along with a chip/programmer, and other performance upgrades like exhaust, regear, etc. is that mileage possible? Or is this guy just lying to me? I really like the truck, but I am new to the F-series, powerstrokes, superdituies, etc, so I am clueless.
That's what he said, 250 miles on a half tank. You're saying 10mpg loaded or unloaded? I know it's not going to get great mpg, but I wondered what you all thought And what I should expect. I have no clue, that's why I'm asking you guys. Are there any members with 46'' tires?
Just saying "I did this that and the other and the fuel gauge only dropped to 1/2" means little to nothing. Can anyone say for sure what size tank is in there or if the sender is reading correctly? Nope Only way to know is to fill...run...fill....calc and then do it again.
I know, I'm just going by this guy's word. I looked up the truck and it's supposed to be a 38 gal tank. And actually, most vehicles still have a gallon or two left when you hit the E line. And I have no way of testing or manually calculating this myself. The truck is a little over an hour away and I don't think he would like me test driving it and using the whole tank to guess mpg lol
Pulling my jeep on a car hauler, 70 - 75 mph on the highway with cruise set, I get 11 - 12. Stock drivetrain and 265 tires. I just can't see 13. But I bet the truck looks bad a$$ though. Post a picture!
I don't know of anyone on here with tires close to that size. Bout the biggest you will find is 40s. I'd say with those tires, if you got 10-12 mpg, you'd be lucky.
I don't really think it's possible, with that setup. See my sig for my mpg, and most of those are my wife driving it conservatively.
x3 it looks great!
