b19bal,
know motorway driving is due to my none constant driving as i come off boost and the back on boost back off then back on boost again ( thats fun and i dont mind that tbh
THAT is your problem.... Just once, tomorrow, try to cruise at 70 and see how you go
Remember this saying:
"Drive like a tw@, pay like a tw@"
And as for leaving it ten mins to warm through. 60 seconds then get her moving...
If you left it running long enough you could get 0 MILES to teh gallon, and that would be the cossies fault too would it? Its your job to spend as much time as possible going FORWARDS with the engine running
