MPG - does this sound right?

[acemodder]

Hiya

I put in £20 worth of fuel 2 and reset my mileage counter.

When back to the red as it was prior to puttin in the £20 I checked my count and it was showing 115miles.

I paid £1.119 per litre.

My car is the ZS 120 standard. My MPG seems very low.

And out of that 115 miles around half of it was motorway driving at about 80mph.

Just worked it out and thats 28.9mpg.
