before CAI averaged 14 mpg, driving hard and 75 on hi (60%hi/40%city)
after averaged 17 mpg

 

On my last tank I averaged 16 mpg. I do a lot of in the city, stop-n-go driving.

 

My friend had a 97 shortbed 5 speed 2wd and he said he was getting around 22 with his, sometimes as much as 25. I get 15-17 with my 95 300 I-6 5 speed 4x4. If you're stuck in the city, it ain't gonna get much better.

 

I say BS. 16 to 20 is more like it.

 

To be honest I have the K&N air filter (not the whole replacement thing just the filter) a throttle body spacer, 40 series flow masters single in dual out, and my MPG still its bad, it maybe raised my MPG by 1/2 mile per gallon, if I would get any thing get the throttle body spacer you can really feel some added mid range power but as far as Gas Mileage it doesn’t help a whole lot!!
Pretty much if you drive a truck expect bad gas mileage, I mean even if you get an extra mile per gallon, if you have a 20 gallon tank you are only going to get 20 more miles out of the tank, which is what a little more than a gallon. I don’t think it’s worth it to spend hundreds of dollars just to get an extra mile per gallon (especially if you are not going to keep the truck forever). I put all that stuff on my truck to make it look/sound better. Just some food for thought.

Are you serious, That thing has been dyno proven to hurt power #'s. That is more of a power adder for a carb, but I guess nobody gets the same results.

 

I've heard of people getting 22 mpg, but that would be some slow driving. Never going over 55, and very slow take offs. Def. no city driving.

 

I've got a manual transmission, so to conserve on fuel I shift at lower RPMs. It's not near as fun to drive, but driving it like that for 400 miles resulted in 24.5 mpg up from 22! I don't drive like that all the time, but if you're needing to save some gas money (roughly six bucks per fill up) it might be worth it.

 

Maybe you can get better than 20 with 3.08 gears, but I doubt you can with 3.55's unless you cruise at like 55. Last trip I took, cruising at 72 on level ground (I-55 in Illinois) I got 19.8. Running it up to 80 killed it down under 17 - granted, that was not level ground (I-44 in eastern Missouri).

 

well you have to spend money for get good mpg.

 

Fixed

 

You guys should be lucky you don't have a 4X4 and a V-6, my truck can't suck own gas fastest enough

 

I'm not a scientist per se but this is the science behind the theory. Filling the tank in low ambient temperatures (preferably early in the morning) is because the molecules of the gas are closer together. That means that for every gallon of gas pumped there are more molecules in that gallon. In other words, the density has increased (more mass of fuel per volume unit). The meters on the fuel pump measure volume, not mass. So as you see the actual economy of the vehicle doesn't change, you actually get more fuel for your money. Hope that helps.

 

The tanks in the ground are usually below frost line which makes the gas temperature fairly consistent throughout the year. However, the gas from the tanker will more closely reflect the outside ambient temperature. I have loaded gas at a terminal and there are all sorts of geological information printed out on the shipping papers. A lot of times this will adjust the actual amount loaded into the truck. I would just buy your gas when you need.

 

Just remember also those big tires you are turning will suck gas faster than anything out there. I bought my f-150 with bfg 315's on stock wheels I know they bulged so bad. I sold the wheels and tires got the helo maxx 6 and went from a 315/17 to a 305/16 and my gas mileage went up 1.5-2 mpg depending on my right foot of course I was geitting 11.5 and now I average 13 I'm sure I could get 16-18 if I went with a 265-285 tire setup.
