Good Day, I'm new to the G6 Owners Club and a fairly new owner of a 2005 G6 GT.
I got a question related to the Driver Information Center (DIC), with reference to the estimated fuel economy display. This question is more or less directed to the G6 owners in Canada.
The DIC is capable of displaying the average fuel economy in either:
1) Metric - Litres/100Kms; or
2) English - MPG
It appears that the DIC has been programed to calculate MPG using the American gallon (where 1 gallon = 3.785 Litres) instead of using the Imperial Gallon (where 1 gallon = 4.545 Litres). The reason I say this is;
I observed the display reading of 10.0 Litres/100Kms in the metric mode. When I changed it over to the English mode it displayed 23.5 MPG. 10.0/Litres/100Kms converts to 28.2 MPG when using the Imperial Gallon.
Have any of you Canadian members observed the same? Or am I unique? If so, is there a simple fix like a software change, E-prom, etc?
I've emailed GM Canada twice over the last few weeks, with no reply.
