Miles per Gallon - Canadian Car

[rickfen]

I have about 30000 MILES (not KM) on our 3.5 G80. Driving is about 50% highway, 50% city. I am not a "slow" driver and occasionally "drop the hammer" cause it's such fun with this car. My overall mileage has been 10.3 litres per 100 kms - which translates to approx 23 miles to US gal. Not terrific, but still pretty good for a car with this amount of HP.
Just for info (a lot of the highway driving has been in SD and west at 80 mph)
