[Shop-talk] Yukon Denali fuel totalizer

[old dirtbeard]

Dear Karl,

My first guess is that all is fine. The MPG on GMC's can be reset whenever 
you wish. So if this vehicle has seen a good deal of 11-12 MPG work, it 
could account for the total gallons vs MPG ratings that you see.

Reset the MPG and see what you average. The previous owners could have had a 
boat and a heavy foot.

best,

shook
