Ian C Posted February 24, 2020 Share Posted February 24, 2020 I have just bought a 2008 ALphard 3litre and have calculated the fuel consumption to be 15.5 mpg. Is there any advise as to what could be causing the low reading . I took to a garage who changed the spark plugs and tested the emissions and which are in the acceptable ranges.
