Re: MPG

yeah ive looked into that and ppl have said i could pick up 1-2 mpg, and i have a shifter improver kit i need to install, which should give me better mpg too, but im looking to push the high 20's, and right now at best i get 19-21mpg

What model is it? Manual or auto?

if it's manual you could try staying at 60pmh in 5th in the slow lane on the highway and upshift before you hit 2k around town... but that's unrealistic.

If you really want to be hard core, a CAI and a tune for mileage on 87 with a 2.9 rear end would probably get you around 5 mpg more but you're looking at over a thousand bucks to make your car slower... that's an abomination.

Re: MPG

oh yeah i forgot, over inflating the rear tires and drafting big rigs on the highway is how you do it for free, I went through that phase with my Dakota (had a 4.7 magnum that got about 11mpg)

Re: MPG

Underdrive pulleys will help a MPG or 2.

Re: MPG

by the time you add a useless pulley, cai, tune, and exhaust, you could have used that money for gas for the next year or so.
I easily got 22-24 mpg city with my stock 99 v6 I had and managed 30 mpg when I was in Idaho making road trips. After that I added mods and it never returned as much mileage as before.

Something isn't right if you're barely squeezing out 21 mpg. either driving habit or something maintenance even though you say it's up to date on all that.

Re: MPG

Yah I agree with the above statement. If you're just trying to gain mileage, the money spent on those mods will take forever to pay off. I'd try some maintenance things and the tire pressure.

When I drove down to beaner's in Iowa, I spent less than $50 on gas for the entire trip.

Despite manufacturer's claims, I think the average pony gets 21-25mpg tops.

Re: MPG

I could easily top 30 in my V6- 02 auto, tune. I get around 24-25 in the cobra on trips. Can't argue with either. Alot better than 12 in the bronco.

Re: MPG

Is your car paid off, or do you consider spending money on a car payment and less on gas a good way to save money? Sounds like Obamanomics to me.

Re: MPG

for the money you could get a K&N Drop in filter, replace the muffler with something less restrictive, run SEAFOAM through all the cycles (fuel/oil/intake) usually frees up a little hp and mpg. Always helped with me and its only like $7 a bottle and you can do all three with one bottle. Just wait till your next oil change and do it then. With doing these things I average 28-30mpg town and 34mpg highway. I also shift at 15-1600rpms where I can when Im just cruising ( I run first out to 2k rpms bc it hits 1500 too quick to bother).

yeah but $150 for a brand name CAI will take you years to get that mileage back to make it worth the purchase. I had pullies and all that crap and noticed nothing until I installed my diablosport tuner. by then I was paying more for premium gas and got less mileage cuz it was easier to make more power.

The one thing that really did boost my mileage about 2 mpg was changing the o2 sensors. Yeah they're expensive but it will help performance and mileage so I'd say they're worth it.
