Hello out there.

 

Picked up a 2008 Yukon Denali past Wednesday. Family of 6 out grew 1997 mountaineer. First 60 miles, it was averaging 8 mpg and now with a little bit of highway miles, it is giving me just a bit over 10mpg. Wife doens't know it will cost us about $120 per fill up. Someday, she will finid out...

 

Great to be here.

Welcome aboard! give it a few tanks before you attempt to calculate your MPG's, if that doesn't help, seek an ECM tune by a professional. A friend of mine does this and he has performed the tune on a number of GM's and I never hear of one coming back with a complaint usually it's "I can't believe I'm up 2 MPG from just a tune" Best of Luck with it, sounds like a beautiful truck.
