Cut your hair and stop wearing socks. The weight savings will certainly help a lot. Helped improve my mileage by 2MPG. Swear.

replace the current engine with a 4 Cyl. Cummins Diesel.

well one thing you can do is get the 08 tahoe

they came out with a hybrid.

but if you want to do something else top three things

chip programmer, air intake, and a high flow exhaust.

on my truck I used to get around 13.5

I got it chipped, new high flow intake, and a high flow exhaust now I'm getting

around 17.5. although it was not cheap it will pay off in time.

I'm no expert but can't some of that gain be attributed to the fact you own a diesel? Tuning always seems to have more of an effect on a diesel engine than a gasoline engine, at least with power output, does the same hold true for efficiency?

Buy a Cold Air Intake from K&N

Like this: http://www.knfilters.com/search/product.aspx?Prod=57-3023-1

I didnt know your year or motor size so i just guessed. I got one for my dakota and it made a Huge Difference! Hope this helps.

Also try to get a new Cap and Rotor and spark plugs and wires. That also helped too. Let me know if you have any questions!

From what I have heard, it does help maybe not quite as much on a gasoline engine as a diesel engine. But he was asking anything that would help his mpg. And those things would help his mpg.

Get a Geo Metro..... those 3 cylinder engines are freakin HAWKS! lol GO forever without fueling

what that bisch up there said... air filter and programmer help...

whatever helps make your engine more efficient work less...

umm most importantly weight makes a difference... whatever you dont need to carry around with you... take it out...

100lbs of junk means ur car has to work just that much harder to get everywhere.

most importantly is your driving habits, accelerate slowly and time your lights so you don't have to stop as much

Get a Wait4Me tune to improve mileage by about 1-2 MPG. Keep the RPM under 2k ALWAYS, and keep your tires full o air/balanced correctly. Biggest things that affected the MPG in my truck. I average 21-22 per tank and I do a lot of city driving.

Silverado w/ 4.8L V8.

keeping rpm below 2000 is quite impractical...

doable... but impractical.

New filters, exhaust, new plugs and clean the injectors, drive between 1-2k rpm.. get a Tornado air thingy... Put seafoam in a fresh tank of gas

Just stop. You're not allowed to talk about cars anymore.

Yeah, a Tornado, and some of those Gas Pills, if you can't find them use moth balls.
Get an extra battery, so that your car will use more electricty to run rather than all your gas.

LAWL.

Diesel much? With those mods, you're not getting what you should have out of a diesel engine. They should be doing better than 13.5 mpg combined, without any mods.

Kinda what I was thinking.
