Welcome, Cruise control is not very good for fuel consumption.

A change of engine oil will always reduce the MPG on a diesel engine until it has "worn" in a little ______________________

yes I agree, I also can get more mpg using my right foot instead of the cruise control. Iain |

Yes would agree but get more MPG on way home "uphill". Always use cruise control to do the comparisons. The car is an Auto would that make a difference? Interesting note about the oil change I did wonder if the cause was the service. |

There was a thread on here recently regarding some members felt that the mpg fell as they approached a service interval. |

Could it be due to the new oil vissc, viscossa, viscosittitty, visccossatt....oil thickness.... and therefore the engine having to work harder |

the oil being new and thick theory is a non starter. When new oil is at operating temperature there is no difference and no effect on mpg.................ie the engine does not need to work harder.

Thats definitely happening with mine - 15 days to go and I'm getting about 25mpg Will mention it at service to see if it can be resolved - usually get around 28-32 even with short runs (Air con on ECON) There's always a way forward! 2008 Freelander Td4 GS - Stornoway Grey - Now Gone - Sob 2011 Freelander Td4 GS 150 - Rimini Red - in its place - Better x far x 4!! |

Trust me, new oil will affect the MPG which will go down initially after service. ______________________
