Engine: D5: - MPG, Performance and maintenance questions

Talisio · Sep 20th, 2018, 20:07

Hi folks, have recently purchased a 2008 D5 2.4 automatic volvo. Now, baring in mind I am not a mechanically minded person, I have a few questions I was hoping someone can help me with!

I checked online and the reported MPG figures are 45~ ish.

On some motorway runs, I will get this. Other times, doing the same run at the same speed, same load, I will get 38. In short, my MPG seems to be quite inconsistent.

My tyres are kept at the right pressure, and smooth driving on all runs. I read up that the DPF cleaning process can cause an impact on the economy, how often should this happen roughly? Is there a point where the DPF needs some kind of intensive clean or, heaven forbid, replacement as it becomes to blocked to clean itself?

The car has a full service history, but as with anything, there is no way of telling how reliable this is! What serviceable parts would play a leading role in economy?

The other question I have is regarding performance.
If I plant my foot, the car handles like the Starship Enterprise on steroids.
Average driving, everything is fine.
When pulling away, 1st and second gear pull fine with medium/heavy acceleration, but gentle acceleration feels a bit sluggish and hollow. Is this normal?

If I have not mentioned anything I should have, let me know and I'll add it. Thanks for taking the time to read :-)
