I saw this and was extatic at first because the two V10s we have at work i dont ever recall getting better than 12mpg
the one is an E-350 van that is usually in the 9 range when i drive it (genetic lead foot)
and the other F-350 regular cab got 12 once when i drove it back from my buddys lake house, all dirt roads at 55 witch is the sweet spot as far as i can figure

Im looking for a truck and seeing that you could do that in a v10 i was about to dump the search for a diesel right now !

 

Impossible to get over 9-10 in the city.

 

I agree and since it's all back roads to get to my job it's killing me with the mileage. Averaging 10-11.5mpg
I probably don't get good freeway mileage either. 70+ is my usual speed. I'd go insane at 55mph!

 

Oh thease were those perfect country roads with curves in em, 55 is about the top speed you would want to go unless you want to dig yourself out of a ditch

 

I only got 2WD so wouldn't be fun lol

 

Hello, I have a bone stock 2000 4x4 4 door V-10, 3.73 gearing 2000 rpm at 70 mph (or really close to that) and i average 11 mpg hand calculated, daily driving, and have seen as high as 13 mpg interstate. I am curious if anyone has switched to an electric fan and seen a positive result. are there any mods that have hit mpg home runs?

 

I know that a lot of guys (when not towing or hauling) will over inflate the tires to get less rolling resistance
The science behind that one says you should improve by about 1/2mpg (thats what people say their is a lot of conflict on the internet, some places say yes, others say no)

I have also heard of guys (and seen a few cars, mostly jetta tdi's) where the guys put bigger air intakes on them and better cooling systems. This thought is based off the idea that heat is wasted energy. They claimed a 2mpg improvement
Idk what that would mean for a v10 but thats something also

Finally its a weight thing. Its basic physics that it takes more energy to move something bigger up to a speed. The bigger object will have more inertia but takes more energy to get it up to the speed.
So if you have some stuff that you could take outta your truck than it should help you out also. Idk about that for you, everything i carry i consider very important but maybe you have some stuff you dont think you need so take it on outta there.


Its a V10, all the reading ive done says that if you want fuel millage thats gonna blow your hair back its just not the truck for that

 

I've voiced my experiences with an '06 V10/F350/4.10 gears above. What did you get for gas mileage BEFORE the ethanol in gas requirement. For mine, it was a loss of about 1.5 mpg local driving and about 2 mpg open road. Ethanol gas (10%) has about 76,000 Btu/gallon vs about 116,000 Btu/gallon or a loss of somewhere near 35% in energy. This translates into a heluva lot of miles per tankful to satisfy a really stupid gevernment edict about 'green' energy and the 'savings'. You wonder why gasoline is so expensive? Why gas mileage is so crappy in big vehicles like a V10 powered Super Duty? It costs more to build, operate and ship that same quantity of alcohol then it does to bring a ship full of crude from a garden spot like Saudi Arabia then refine and distribute the product. Now in my wisdom, I'm worrying about when the pols will force me to buy biofuel for my current diesel powered truck and what that crap will do to 16 mpg local, 20+ highway.

Sorry. My soap box has been put away for the night

 

I wouldnt worry about Biodeisel, i have two buddies at school. One has a 2500 DMAX diesel (i think its a 2010) and he runs a biodiesel-petrodiesel mix and he said the only thing that he has noticed is the same millage and the need to add anti gelling to the fuel in the winter. He said its no big deal and saves a lot of money on his drive

The other has an old Merc diesel that he runs biodiesel in, same situation. Good millage just needs to add additional chemicals in the winter

So your good there


Im more pissed about ethonol. Idk if anyone here has, but i always am replacing the fuel lines on my 2 stroke grass mowers, weed whackers, hedge clippers and it mucked up my old golf cart and quads something terrible.
Its just someone up on the hill who thinks they are an expert on engines but instead all it does it muck it all up.

what did they do it
cause they always think they know best, very rarely do
