The aerodynamics are all changed now. The only thing you can really do to get some of the mileage back is to swap gears to something lower.

Also, engine mods like headers, cat-back, capacitive discharge ignition (MSD, Jacobs, Mallory type), cold-air intake, and then internal motor mods to increase horsepower to overcome the changes.

Gas mileage is one sacrifice that has to be made when building a functional 4x4. It sucks but I'd still rather have my truck than a Honda Insight.

I am with Outlaw. Gas mileage sucks already, why not just build what I want and make it worse? If I was hoping for good gas mileage, I figure I would have had alot of other things to spend the $3500 for the lift & tires I spent! <IMG SRC="/board/images/smilies/icon_razz.gif">

I also agree with Outlaw, I would rather spend my money on gas and enjoy the look and performance of my ride than be efficient and drive a honda. If you give a little, you get a litte. Just suck it up and pay the extra money for a couple of more miles and spenda little bit more money and go for Mud tires instead of those more efficient All Terrains. It will all pay off when your having fun in that mud.

You could change the aerodynamics of your truck a little more. Either install a camper top or a bed cover, or drop your tailgate. It reduces drag a bit, which should result in better fuel economy. By the way, Northern Ca. is currently about $1.50 a gallon (better than $1.90), but i'd still rather drive my truck. Which gets between 9 and 16 mpg. (depending on conditions) Than a more fuel efficient Mini-Car. I don't fit...and i'd rather run one over than actually own one.

Regular is $1.17 in western Maryland <IMG SRC="/board/images/smilies/icon_smile.gif"> Supreme was up to $1.95/gallon over the summer, kinda sucked cause my bike needs supreme. Atleast it got 45mpg off it.

I've noticed a difference in my gas mileage as well. I lifted my truck 5" and went with a set of GoodYear MT/R 35/12.50/15. I have a 5.2 and before the mods, a full tank of gas would take me about 280-300 miles, now I'm getting anywhere from 230-250 miles on a full tank...It sucks, but I'm very satisfied with my modifications and wouldn't go back to stock!!! <IMG SRC="/board/images/smilies/icon_biggrin.gif">

Oh! I didn't think about that??? That's true! Can anyone else elaborate on this? The ram's have a digital odometer/trip meter, so if I buy something like the Superlift Speed Calibrator, my mileage will be more accurate?

The Superlift speed calibrater is supposed to work. I just don't have the money for it yet. When my truck was stock, it was wearing 265/75/16s. Now it has 315/75/16s (35x12.50). My speedometer is off by approximately 5mph...i'm going 5mph faster than my speedo says. Also, my odometer reads about 10% less than stock. I followed a friend (him in his stock Oldsmobile, me in my rig). His odometer read 250 miles by the end of the trip. Mine read 225 miles, just add 10% of your trip miles when you fill up and take the average.

I have a couple possible programs (I'm emailing you about it now Jason) that would be very helpful in situations such as this.

What they do is you enter in your stock tire size and the new tire size, and it'll tell you how far off your speedometer actually is.

Thanks guys! I feel a lot better now! I thought that by adding my lift and bigger tires, that I lost almost 50-75 miles off my gas mileage...I knew about the speed being off but never even thought about the gas mileage being off!!! <IMG SRC="/board/images/smilies/icon_biggrin.gif">

Just a little side note... All of the measurements, speedo, odo, trip, will be off by a percentage. The faster you go, the further off it is. so lower speeds are still pretty accurate either way.

Bob,

You can see a picture of my Ram here on Readers Rides or on my homepage:

Ah the benifits of having a lifted vehicle. Take money directly out of wallet and hand over to gas attendant. Between smoking and paying for gas I can't even afford to do anything. :wall:

this isnt really true. as you accelerate an area of high pressure builds in the bed and acts like a "cushion" to keep most of the other air from causing drag on your tailgate. plus the sudden drop at the back of the truck with a shell will create an area of loww pressure there which wants to "suck" your truck backwards which creates more drag.
ok kids thats my lesson for today. your dismissed. lol :p:

Oh, you think that's high?? This morning it was $2.19 for 87. It's even higher on the other islands.
