    It sounds like you are getting 12.5 miles a gal or 20 KM per 3.78 liters. Which is ok for the city, but not so good for the hwy.

    How many miles or KMs on your tahoe?

    I have 211,000 Km or 131,000 miles on it

    It might need a tune up (Fresh spark plugs and a good air filter). 12.5 MPG is pretty low on the hwy.

    when i buy the truck the old owner said they change them 2 or 3 years ago, but dont remember when exactly and how many Km since... so i will make a check and put a new air fliter on it.... do you think a new fuel flitrer can be good to... thanks for your advise.

    I get about 18 mpg with my Yukon Xl on the freeway, but that is driving 67mph (107.82 kmh). If I drive live an old lady I get around 15 mpg in the city. If I drive it hard I get just over 13 mpg. How do you drive? Slow accelerations and light braking make a major difference in fuel economy. I try not to stop at red lights. I slow down early and continue rolling to the light. It takes alot of power to break the static friction when you stop. You can experiment with this by hooking a fish scale to a toy car, put a small weight on the car. Slowly pull the scale and watch it as you get the car to move. You will notice that the force to start the car rolling will be high, then when the car starts moving the force on the scale lowers significantly. It took a lot of adjustment over the last few months for me to get better fuel economy. I sometimes find myself driving like I used to, I can look down and watch my economy decrease quickly. Try driving conservatively for the next week and see if you economy increases. My rule of thumb is, If the car behind me is not getting pissed off about my slow acceleration from a red light then I am driving too fast.

    i remove the master flow and i found they are a lot of dust int the grill, i clean it, and do a combustion chamber cleanup, and an intake cleanup, the result, as been see right after, i increse my fuel economy, by 50% now, its a big step foward,....
