Just wondering. I am only getting 12-13MPG in my 99' 4WD Yukon. The gas is killing me!!!!
What type of powerplant do you have?
Chevy Truck Parts
I have a stock 5.7 with the 4L60E auto transmission.
What kind of gas mileage are you getting
I have a 2004 Yukon XL loaded and love it. I am getting 14 to 15 MPG at most I believe I have a 3.73 rear end and 5.3 flex engine. I had bought a Hypertech Programmer III to help try ang get more MPG. I loaded the program and took off to San Antonio I averaged 15 to 16. Not exactly what I was looking for. Does anyone have any ideas as to what to try to get more MPG?
That's the million $$ question.
Keep your tires inflated properly. Don't do jack-rabbit starts. Keep your engine well-maintained, etc.
I have talked to countless people about the mpg. There is always some response to more air flow, change exhaust, program, rear end gear ratio. Will keep looking.
my '05 2 wheel drive tahoe w/ the 5.3 averaged 16.4 on the way to and from jersey to SC. that was w/ no after market add ons, but obviously a lest constricted engine will flow better, so im looking in to some sort of intake, anyone have any suggestions as to which is the best one to get?

Try this for a start at least:
I just bought a 2001 Yukon 4x4 and drove it from Flordia to Colorado and averaged 14-15 mpg doing about 70 to 75 mph on average. Over 2100 miles
That's really good mileage for driving those speeds. What engine do you have in it?
