Hi Trevor My "rule of thumb" calculator, which is usually fairly accurate, indicates that the domestic rate of the fuel you purchased was actually around 87p / litre. Ouch.
I use domestic rate +43p for propulsion rate, so I work it out as (at
71p) 96.53x80%=77.2 litres at 71p =£53.25
96.53x20%=19.3 litres at (71+43) =£22
A total of £75.25 give or take the odd 20p
