Hi all , iv got a 98 , r plate 2.0 20v, and last weekend i had my exhaust rear box repaired(loadsa welding) and whilst waiting for that to cool i ditched the battery and cleaned ,re-gapped my plugs,done the usual oil n water checks, and tyre pressures , the price of petrol was 111.9(total garage near dagenham pool) i put in 5gallons and iv just noticed iv done 257.6 miles. This includes 130miles of motorway driving at 65-70mph and the rest is round town stuff , can anyone tell me a formula to properly work out my true mpg and also if the above is good/average or 'bugger me ! -how much??'.
Many thanks ff.
