Corsa-B.uk - Vauxhall, Opel and Holden Corsa B Owners Club

Hi i have a 3dr 1999 corsa club 1.2 16v I was wondering what would the endurance be it has a 45 liter tank if the tank was full and say the cars on the motor-way with an average speed of 70 what sort of mpg could you expect I know it varies on lots of things but just give an approx

depending on conditions like:
is car fully loaded, tyre pressure, weather etc etc
id expect to see about 40mpg so for a 45 liter tank should be about 375miles per tank give or take

that would be if you constantly managed 40mpg, as this is impossible its not really easy to work out
