Fuel Economy: What is your average MPG?

[coolasice]

Just wondering what every one is getting out there..according to my driver information center I used to get 13.5 I cleaned my throttle body dropped to 10 (don't know why)..changed valve cover gasket down to 8.5 noticed oil leaking out of vvt solenoid changed that and now im up to 11.3..I used to complain that 13.5 was bad...how I wish for those days again

That's about right for mine, around 11mpg all winter, in summer it averages 13-14 unless we travel and i can get upwards of 16 on the highway.. i don't have D.I.C. in mine

On my 04 GMC Envoy XUV (6040 lb beast, actual weight)with a 5.3 and 3.42 gears. I get 16.8 on summer fuel, and 15.3 on winter fuel. I am quite a spirited driver, so that likely needs to be taken in for some drop in fuel mileage. Engine is completely stock, and original with 193k miles.

I guess mine is pretty good then.

@Mooseman do u have the dic? and if so does it come close to what fuelly said or is it a lie like that oil pressure indicator on our dashboards..

 

[Mooseman]

I just recently installed a cluster with a DIC and haven't done a comparison yet.

Ok

11.3...down from 13.5 pretty much the same driving habits

I do have a large leak code that I'm going to try and locate though so maybe that's it

Took my new Advanta SVT01 off, and put my 66k mile old Michelin Defender LTX M/S tires on, and fuel mileage jumped up 1.5 mpg. How does that work?

The trucks are weird..removed and cleaned throttle body and lost 3.5 mpg

DIC says I average 17.2 but I calculate it every week anyway. I got 16.9 last week and I've been hammering it more because cheap gas.

 

[coolasice]

just filed the truck earlier and calculated 16.5mpg.... woohoo!

This is an old thread, but thought I would add. I have had my 2007 Trailblazer for 7 years now and put 41,254 miles on it. I average 14.66MPG overall with my best being 17. I up until this spring I mainly drove it back and forth to the office (2 miles round trip) and to pick up my daughter from Pre-K (same distance). Now, weather permitting, I ride my bike to the office and to pick up my daughter.
