I Would Like To See Some One Compare Auto Trans Vs Manuel Trans Mpg. Around Here From What I See The Manuals Get A Lot Better Mpg Than The Auto.

 

Gettin' about 16 no matter how i drive it (except towing) or how much i mod? can't figure it out. go about 380-400 on 25-26 gal. the gf's gets about 20-22 in a 2wd qc 2500. hoping to get better (ordered the goerend tranny for it today) once the tranny's in and put an ez + bhaf. bhaf's in the toolbox waitin to go in. if injectors don't help i'm gonna try stackin' the sc tuner and ez.

 

On my last tank I hand calculated 15.8 vs 22.4 on the overhead. I had a hunch it was off, but by almost 7mpg??? I left the Comp on 3X3 for the whole tank and only rolled into it a couple times ...I swear. I don't even want to think about what I'm getting this winter when my overhead drops down to 12.5mpg.

 

Is there a common thread here with 24V versions? The 5 & 6 speeds always get better mileage than autos?

 

Anything over 20 Mpgs in our trucks I have to wonder if they are using the overhead display or doing the mileage calcs in their head, both seem to ere on the high MPG side. My sister in law always gets fantastic mileage in her car but when asked how she figured it out she goes I don’t remember

 

My last hand calc is 20.4. I usually avg 19.8 driving normally. I never trust the overhead. I do use Stanadyne and noticed a .5-1 mpg increase. I found a pretty good free FuelCalc program for the Palm PDA that calculates cost per mile and it's tells me I'm paying .13 cents per mile with the current fuel prices. Just another interesting useless fact.

 

Be nice to be able to write off the mileage on yearly taxes. Based on the current reimbursement at $.485 per mile thats pretty good.

 

Aint got one. All hand calculated.

 

Thats another reason to love these trucks. Thats great MPGs. Of course at over $3/gal it still hurts. With mileage like that you out to go out and give your truck a hug.

 

Can't talk about those kinda things on a public forum. We have a special bond.

 

Your getting exceptional mileage for a 4x4!

What's your correction factor for your 315's?

How fast do you drive? At 80+ I get 17 but know if I would drop to 65 could do ALOT better.

I am getting about 18 around town if I keep my foot out of it.

 

10%

I'm not a fast driver. 65-70mph, I use the cruise control whenever I can. No hard/fast excellerating. On every vehicle I've ever driven I've been able to get acceptional mileage. We had a turbo convertable Vw bug and with me driving, 33mpg, with the wife driving it dropped down to 28mpg.

 

Assuming your 02 came with 265's....my conversion chart shows only 8.5% adjustment needed.....but that would only change 22 mpg to 21.6 mpg.

So heres the question-> Whats the average of everybodies average? 18? give or take? That would be a potential buyers question.
