Re: Fuel Economy Survey

["Fred Munro" <munrof@isys.ca>]

Fuel economy on my '91 200q with the 10v MC-2 engine averaged over 130k km
of driving was 10.4 litres/100km (22.6 miles/USG). Standard deviation was
0.83 litres/100 km (1.8 miles/USG). The fuel economy was the same at 281k km
as it was at 150k km when I bought the car.

'94 S4  91k km (first economy data point: 11 litres/100 km)
