Guys as i dont have an OBC i have little means of working out how much fuel i am using, just the fuel bills but im sure im over fuelling.

I need to know whether you think this high.

Usual day, short trip - school run (car fully warms up though) 3miles max
Trip to work - Motorway run average 70 - 80mph distance 26miles there and back.

So each day an average of 30 miles call it. Add on a bit for the weekends and call it approximately 60miles a week distance.

I am spending approximately £45 a week on fuel = 75p per mile.

Lambda light is on and has been for some time, (gonna get the codes read this morning hopefully) Could be O2 sensors????

Does anyone else doing regular mileage per week spend this amount on fuel?

Help me Obi Wan Kenobi your my only hope.......
