Good quality oil.

The TD6 should be returning a higher MPG in this warm weather, colder weather uses more fuel

your service might have done a proper reset on the fuel consumption computer so the best way to find a 'real' average mpg is to do a tank to tank fill... ... - .- -.

stan... does the cold dense air not just give better combustion and a bit more power due to a better burn? hence the reason that jap car tuners fit large front mounted intercoolers to ram as much cold air into the system as possible.

i don't think it has much effect on MPG???

someone please enlighten me if i am talking rubbish!! Current: TDV8 (3.6) RRS HSE

you could be correct stu, but if the combustion is more efficient then you need less fuel to get to required speed.. ... - .- -.
