Fastlife91 Posted October 28, 2015 Share Posted October 28, 2015 Hi I have owned cars in the past and they have had bad MPG, so when I bought my current car, a 2006 mk2 focus 1.8 TDCI sport, I bought it as its a car I've wanted for a while and it was diesel and the mpg figures didn't look bad Car has 52.7 litre tank 39.2 extra - urban 64.2 mpg - extra urban 52.3 mpg - combined I sometimes get 400 miles, sometimes a bit less and that is from full tank until light comes on, that is with driving very lightly. That is mostly urban and little extra urban. Today I looked at how many miles I'd done since filling my tank a few days ago, it read 267 and my tank was only quarter full, I decided to put more fuel in and fillthe tank to the top and it cost £32. Does that mean 267 miles cost me £32 ? At the moment my car has problems with the maf wiring loom being torn and reading open circuit hence engine light on, will my mpg improve once that is repaired ?

alexp999 Posted October 28, 2015 Share Posted October 28, 2015 If the car can't measure the incoming air it will assume worst case scenario and will end up using more fuel. Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted October 28, 2015 Share Posted October 28, 2015 Yeah the faulty MAF won't help, I lost about 5mpg on a previous car with a faulty MAF. If it's any comparison, my 1.6TDCi cost me 8.3 pence a mile over the last 460 miles, 59mpg. :D You really need to know how many litres you used or how much a litre cost to work out your MPG properly though. But going on what I paid this week, you're only getting 42mpg, which is pretty awful unless you're sitting in traffic or at 90mph all the time lol.
