Well the maths says that for every gallon (4.54 litres) i got 49.54 mpg at 75-95mph so for 60 miles its roughly
5.70 litres
Ooooh... I thought that a gallon=3.78lit, i did't knew that british gallon had a different rate...!
Btw.. I burn, 6.5L but with 60-70mph... I can't understand.. Stock chip/pulley, new λ, new blue temp sensor, well set co, cleaned injectors.. Is there anything that i haven't replaced that effects fuel consumption...?
