217 miles Ian.
So i calculate that like this:
£26.80 buys you 30.112 litres of Shell Optimax fuel at 0.89p per litre.
That means you travelled an average of 7.206miles for every litre of fuel used.
Multiply that 7.206 miles x 4.546 (litres in a Uk gallon) and that gives us an accurate calculation of how far you travelled for every Uk gallon consumed:
32.76MPG overall
This is on a pretty damn un fuel efficient T4 / Greys / low comp / ported head/ BD14 engine too!
Even im shocked at that!!
Have i fooked up the calculation somewhere?
