so, I bought a 3.5 Elgrand on Saturday, it was totally empty and I put 46.91 litres (10.32gals) of fuel in, the needle went to 8/5ths of a tank, I travelled 90 miles home and the needle reads half a tank remainingg. By my calculation 1/8th of a tank of fuel is 16.72gals / 8 = 2.09gals, this being the amount used, by dividing 90 miles travelled by 2.09gals I get 43.06 mpg! Now even to my crazy brain I know this can't be correct, can someone point out my elementary mistake please
