Fuel consumption is pretty much irrelevant these days... If you are really concerned about consumption - ride a push bike everywhere... that being said there are many things that influence fuel economy and the quickness of people to blame the car irritates me... Driving tired, or stressed, how much of a lead foot you are, quality of the fuel (and not just the type i.e. 95RON, 98RON etc... but where you filled up, the brand and the quality of that particular delivery from the manufacturer), air con, highway vs. urban driving, auto vs manual... it's all relative... also bare in mind E10 fuel is nasty and cheap and because it contains 10% ethanol (which burns faster) then you are going to burn through your fuel faster and get worse fuel economy... I'll happily put E10 in the work car all day long but if anyone ever put E10 within 20cm of my fuel tank on my personal car I'd knock them the hell out... My advice - stop using E10 and put at least 95RON Premium in... you will get better milage, your car will run better and your fuel gauge won't drop as fast...
