[Shop-talk] Yukon Denali fuel totalizer

[Karl Vacek]

I found out that I have a severe case of obsession.  The GM service records 
(obtained from a local GM dealer's computer here) track the mileage at 
services through the three years, and it progresses perfectly.

The fuel usage discrepancy may be due to the fact that some dash instrument 
module (dunno know more than that - I'd have to check the part numbers on 
the service record) was exchanged last September.  They send them in to a 
central GM service center for "rebuild", and it could well be that on the 
one installed the fuel usage wasn't zeroed out since testing, or the last 
owner of the module, etc.

Thanks for all the ideas and suggestions.  Now I can just appreciate how 
nice it is to have a (relatively) new truck !!
