Fuel economy

How many miles should i be getting from 20 litres of petrol on a 1.8 mercedes benz coupe 2005 model?

So many variables, but at 30mpg, around 130miles / 200kms
So, Town driving under 100 miles, but long runs maybe 175 miles.

How far are you getting from cold, on properly inflated, good tyres and just you in the car, with temps above 10c, and on relatively level ground.....?

As per above depends on when and where it’s being driven the maintenance condition and how the tyres are.
~140miles as an average on a good run with some town driving thrown in
