Deteriorating MPG - What to do?

[GerH]

Going to give it a service within the next week or 2 and hope that does something before I start investigating further. Picking up:

Sparks
Oil, Air, Cabin & fuel Filters
Oil

See if that does the trick...

Don't forgot tyre pressure. That could be a factor also

Hi Ger,

Is the car getting up to proper running temperature? Is it taking excessively longer to warm up than normal? Could be the thermo if the across is the case.

Hope this helps,
