Car Forum / UK Car Forums / Car Maintenance (UK group) / October 2007Increase in fuel consumption - what to look for?
I know the pump prices have gone up recently, but a few pence here and there never really made a noticable difference in consumption. I have recently noticed however, that my MPG is less than it was. I have a Polo 1.4, which would usually average about £1 unleaded for 10 miles driving. The recent decrease has seem to car struggling to reach 120 miles on £15 of fuel, with no real change in driving habits. There are no signs of fuel leakage, the tyres are at the correct pressure, all sounds well mechanically, etc...so rather than pay a garage to guess for me, I thought I'd ask on here first to see if anyone could give me some pointers.

I used to find at least 10% better fuel economy after having a new exhaust fitted on our Polo. Steve Evans (Steve Evans <look@my.sig>) gurgled happily, sounding much like they were saying: > I know the pump prices have gone up recently, but a few pence here and > there never really made a noticable difference in consumption.

Go round it and make sure all the wheels are free to rotate easily. If a brake's binding slightly (sticky handbrake cable? Muck build-up on a caliper?) you'll be wasting a LOT of fuel trying to turn it. What age of Polo? Cat? No engine management lights? > I know the pump prices have gone up recently, but a few pence here and > there never really made a noticable difference in consumption.

Reading the other posts, I agree that getting the car serviced regularly will make a difference but do you really kknow what fuel consumption you are getting? The only way you can compare is to calculate it properly. I use miles per gallon but miles per litre is good enough. You need to fill the tank and reset the trip computer. Run through most of the tank and fill it up. Note the mileage and litres used. Divide the litres into the mileage. ie 360 / 45 = 8 miles per litre. Multiply this by 4.54 to miles per gallon. 36.3 in this case. The other thing to remember that it is not only temperature that makes a difference. Cheap fuel brands will normally return a lower miles per gallon. Do you always use the same petrol station?

The fact that the weather's gone bloody cold might have something to do with it :-) Mike P |
