I have a 1.3 diesel multi-jet and i have a fuel problem i cant diagnose. I filled the tank up £30 which took it up to 3/4 on wednesday and today its down inbetween 1/2 and 1/4 of a tank. Tyre pressures etc are right, i dont thrape it around either. Can anyone help please?

It all depends on type journeys your doing and other things. Short journeys eat more fuel. Some supermarket fuels are rubbish. Asda/Morrisons are the worst for going through quick. When was it last serviced. Road conditions I.e start stop etc

I filled my car up to full on Friday it took £60 and it's empty today.
Without all the facts, then i'm afraid the sentence means nothing.

We need to know how many miles you've covered since Wednesday.
