#180 of 185 '02 4x4 1/2-ton Suburban LT fuel mileage
Mar 10, 2008 (8:19 pm)
I've kept real good track of my fuel mileage over the years, a bit obsessively perhaps, and put it all into Excel each year. Here are the results:
2002 - 17.0 mpg.
2003 - 16.6
2004 - 17.2
2005 - 16.0
2006 - 16.8
2007 - 15.7
Some years had a lot more highway miles, obviously. Note, I went by the Suburban's odometer without adjustment to actual, and as I recall now it's about 2% long, suggesting that actual mileage based on real distance covered was 2% lower than the above figures.
I'm not unhappy with our truck's mileage based on it's excellent driving characteristics, utility and reliability. That said, like most people I'd like to send less $$$ to the ragheads in the mideast who use the money to blow us up. So I'm looking forward to buying the new hybrid when they make it available in a Suburban model, and hopefully they'll fix those god-awful middle tumbling seats and uneven cargo floor so that a big Suburban can once again fit a simply 4x8 sheet of plywood in the back like my '02 can do.
'er y' go
#181 of 185 1996 Tahoe Starting and Running Problems (Crankshaft Position Sensor)
Aug 27, 2009 (3:31 pm)
My 1996 Tahoe was having terrible problems starting and running correctly. The initial diagnosis was the crankshaft position switch was malfunctioning. After almost $2000 dollars of replacing the sensor, engine tune-up, fuel filter and fuel pump I was still having the same problems, but not all the time. I had a local mechanic due the work and he said take it to Chevy and have them diagnose the problem, which they determined was still the crankshaft position switch was malfunctioning. Since my mechanic had done the original work I took the Tahoe back to him with the Chevy diagnosis problem. He crawled under the truck with it running and saw the sensor moving around while it was running. He took the sensor out and discovered that one of the mounting bolts screws into a brass fitting inside the plastic timing chain cover. The brass fitting was loose and just needed a screw driver inserted into it to spread it to increase the tension on the plastic cover. My mechanic put it back together and it resolved all my problems, meaning most of the $2000 dollars I had spent trying to fix a problem that ended up being caused by maybe a 25 cent brass fitting in a plastic cover. Live and Learn. By the way my 1996 Tahoe has almost 154000 miles on it with the original engine and transmission.

What kind of fuel mileage should I be getting in my 07 Tahoe (46000 miles)? I have only had it less than a month and it has already been in the shop for a week getting two new injectors and fuel pump, along with some other electrical issues fixed. This is the third time that some injectors have been replaced in this vehicle. I have gone 100 miles since the repairs (half highway/half city) and I am barely getting 11 mpg. Just wondering if anyone is experiencing this issue.

Have a 2007 Sub, and it's been a while since I've checked, but I believe it's in the 20ish range on highway driving. The vehicle is used mainly for highway trips, when used around town occasionally I know I don't even look/check.
It get's better than our older Ford Explorer 6 cyl on the highway 19ish.
#185 of 185 2002 Tahoe w/5.3 is eating me up w/fuel!
Dec 25, 2010 (9:20 pm)
I recently purchased a 2002 Tahoe 4X4 w/trailer package (76000 miles) and have been shocked by the lousy fuel mileage I'm getting. I average in town and highway around 10 to 12 mpg. It desperately needed plugs (burned down to the porcelain) which I changed, otherwise it runs great. I don't know the rear end gearing other than to say it is stock. While it has the trailer package, it was never used tow tow anything (no hitch!).
What should I be looking at next that might improve the fuel mileage?? I jealous of those getting such good mileage! With gas forecast to be 4.00 plus by spring, I need to get it straightened out ASAP!!!
