159 1.9JTDm MPG.
I understand this topic is brought up from time to time, and there is lots of general advice.
However I'd really like your help...
I drive a 57 Plate 1.9JTDm 159 with 40k on the clock, I drive between Leeds and Sheffield on my daily commute, almost all motorway, and with cruise control on at a steady 75mph.
However, after doing this routine for two months, I'm getting 34.8 Average MPG on the trip computer, which tallies with my expensive fuel bill.
What's going on? Are my expectations too high, I would have guessed I'd be getting about 40-45mgp?
Is this idicative of a problem? DPF? Something else? The car is presenting no other symptoms and I've had no historic issues with it.
What can I investigate? I was thinking of trying a fuel additive to 'clear' the engine, any suggestions for a type?
Is there anything else I can look at? If this is not far from realistic mpg figures, then I'm afraid I'll have to sell the car, and I'd really rather not, I've become quite attached to it!
Please help, I really appreciate any input or suggestions,
Thanks in advance!
