Any tips on how to improve gas consumption through a chevy tahoe? Any type of tweaking or replacing. Basically I will get 12 mpg through city and 16 mpg on highway through what company says. Even improving it to take 1 more gallon to the mile will be a big step in my eyes. I love the truck but gas miles just kill me. :X

wait until you get the truck to see how bad it is then ask the dumb questions

high flow airfilter and new exhaust. Exhaust will probably cost more than the savings will be, but will add power and sound better

Seriously.

I highly doubt any mods you put on it will improve your gas milage. Best bet is to get a different vehicle, or keep your foot out of it as much as possible.

If it says 12/16 online you will probably really get about 10/13

Good luck finding a modification to improve gas mileage that manufacturers of millions and millions of large, gas-consuming vehicles haven't figured out yet. If you do, make sure you sell it to them.

Tahoes are not for people worried about gas mileage. :fyi:

Don't accelerate too fast, allow the engine to warm up instead of banging on a cold engine, and stay out of traffic.

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

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.

lol....idk man, my sis has an 07 tahoe that I'm pretty sure cuts gas to the cyclinders or something while cruising on the freeway...think they can get around 20mpg on the freeway..not sure on the city, but you can get your taho chipped to get better mileage..how to go about that is far from my knowlege....

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

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.

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.

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

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.

Buy an S10 V6, and replace the current engine. ;)
