Gen 2 cooper s - 18mpg can that be right?

I decided to see how much we spend on petrol in my wife’s mini as we’re trying to budget. She does 4 miles each way in heavy traffic commuting. (Although it seems further?!)

I brimmed it last Sunday then this Sunday, so I was very surprised she had only done 68 miles and it cost £21 quid and was 16.5 litres. I’ve never checked before.

What the hell! I always assumed it was probably 28 mpg or something. Bit pissed off. The car is in good order no faults.

Damn ok. So I’m stuck in that zone of sell the car and lose a couple of thousand to buy a more ‘economical’ car!

Just filled up again, 57 miles this week but 23mpg! Overall average now 20.3mpg! Not much I can do so I’ll stop looking
