Better gas mileage on my 01 gasser

[samagy16]

Thank You in advance for looking at my concern.

I have taken the liberty of asking here because after reading for a few days I have seen that there is an immense amount of knowledge on this site.

I have an 01 Excursion V10 6.8 and as you well know the gas mileage is horrible, I've had the truck for three years and it wasn't a big factor but gas prices being what they are it has become an issue. I love my Excursion but want to find a way to get better gas mileage.

My truck is fully stock, no upgrades whatsoever.

Any suggestions would be appreciated.

Shoulda got a diesel. I'm averaging 17mpg right now.

I don't know what helps a gasser to get better mpg, but I would assume an intake would help, but I question exhaust. a chip might help.

I got a diesel because the rule of thumb is that as you do performance upgrades, your mpg increases, which is opposite the results you get on a gasser.

But needles to say, heres a for ya

BTW, the V10 is the better gas job for mileage than the 5.4, but they're hit or miss on whether you get a good one, or a boat anchor.

Modifying your driving style will have the biggest impact on your mileage. Slow smooth starts, using brakes as little as possible, no excessive idling, maintain the speed limit. Unfortunately there is a base amount of fuel your motor will always consume...

Kind of stinks too, having a V-10 and not being able to let 'er rip...

My driving style is very gentle. Rarely step on it. Those days are past me. Just wanted to know if there was something beside driving style that would greatly improve gas mileage for my truck. I guess the options are very limited for the gasser as opposed to the diesel. I guess I will look into an intake. ANY SUGGESTIONS??

I have a fitch fuel catalyst on my diesel. Picked my mileage up about 1.5 miles a gallon. I think they make them for gas motors to.

i would go with an intake, exhaust maybe a throttle body spacer some smaller tires might help.

Have you compared longer term (6 mo. to 1 yr.) mileage before and after the fitch fuel catalyst was installed, or just the first few tanks? How long have you had it on your Excursion? I'm leery about some of the claims about mpg improvements. The Diesel Secret stuff used to cheaply create something like biodiesel seems to have been proven to be a fuel system destroyer. The fitch product for my truck costs about $279 plus shipping. That's a big gamble.

Or you could sell your v10 to some unknowing person out there and buy farm boy diesel's 7.3 ex.

Not sure on your Ex, but on a tahoe w the 350 vortec i went with a k&n filter had a free flow cat put on it with flowmaster exhaust and gained right at 3 miles per gallon with out changing driving habits at all. personally have never been impressed enough w/ ford gasser engine mpg to ever buy a gasoline ford motor though.

trade it in for a 7.3 u wont be dissappointed!
