In winter you are getting less MPG because of other factors, you are probably changing gear more, using the car on short journeys instead of walking.Last edited by Paddy; 24 April 2013, 06:53."A people that elect corrupt politicians, imposters, thieves and traitors are not victims, but accomplices," George OrwellComment

All that requires more power = running the engine at slightly higher revs = less MPG."A people that elect corrupt politicians, imposters, thieves and traitors are not victims, but accomplices," George OrwellComment

Originally posted by Paddy View PostWhat I said is basic physics of how engines perform. Cold damp air compresses more than warm air. On hot days, engine performance decreases. It is best tested on a long straight road without traffic.
Cool air is denser - i.e. has more oxygen molecules. All modern cars have sensors to detect the air pressure or temperature going into the engine and can squirt in more fuel to keep the ratio the same. More fuel + more air = more power. Whether that produces better MPG too I'm not sure.
The real question is why does a 2 litre car use more fuel trundling along slowly than a 1 litre car? If they could just solve that, then we could all have twin-turbo 5 litre V8s and still get 60mpg on a trip to the shops.Will work inside IR35. Or for food.Comment
