I'm having a problem with my Vectra. It's giving me quite poor mpg since I bought it in October.
The GID is saying I'm averaging 29.7mpg.
I'm getting 43 miles out of £10, using the trip computer thing.
I've got another DTI in the family which is getting 60 miles from £10.
This is based on £1.38 per litre.
The car service light was on and it said 31000 underneath it a while back. I just reset it.
