I just got my 2007 Denali back from a local guy whom I was referred from a friend. I would never ask a dealer to do this work!

Some info about my Denali.

6.2L Engine
85,000 miles
Average miles per gallon = 13.4

He performed the following tasks on my truck in hopes of improving my MPG:

- Replaced upstream oxygen sensors with Denso brand
- Cleaned throttle body
- Replaced mass air flow sensor (MAF) with new Delco brand
- Added strong injector cleaner
- Replaced air filter
- Oil change using synthetic oil, Mobil 1 5w30 Synthetic
- Inflated tires to 40psi
- Cleared computer codes
- Relearn computer

Parts were expensive but his labor was very affordable and I am happy thus far except the idling is a bit off because I believe the computer is still in "learning mode". So far it is hard to tell the immediate gains in MPG as I have only put on about 10 miles thus far.

The truck shifts amazingly better and has a nice response when stepping on the trottle.

In your experience, will the above repairs help with overall MPG gains?

Thanks!

Eric

As you already have all the work done, why don't you find out and let us know IF and HOW MUCH miles per gallon you are gaining. :think:
