Differing MPG

#1 Post by nelsta » Wed Mar 18, 2009 2:44 pm

Hi there

Has anyone noticed they get different MPGs when using a different autogas supplier? I get the bulk of my fuel from Countrywide, but as I'm now working near a Morrison's that does gas I've been filling up there. The gas is cheaper than Countrywide (46.9p vs 48.3p) and I managed to get 350 miles out of 48lt (equates to 33mpg) on a motorway run. Yet on Countrywide gas I'm lucky to get 30mpg. Is this something to do with the mixture that Morrison is selling?

its to do with the outside temp on the day and the cut off pressure valve switch on the pump. Colder days you can buy more gas so think you get better consumption, if the pressure valve is set to cut off at a lower pressure than your normal pump this will show as worse fuel consumption
