Most of my driving is short trips so I'm becoming a bit concerned about keeping the DPF clean once I actually own a Jag that is.

I've seen it mentioned that a 20/30 min run is required about once a week at around a steady 60 mph. Does this need to be a continuous run. I ask as I go up to town once a week. This trip takes in a quiet B road where I can usually maintain 50/60 mph then a run up the A1 for aprox 10 mins, again usually keeping close to 60 mph.

Overall it takes around 25 mins for the journey. Now for the dumb bit. How would having to stop at a couple of roundabouts affect the cleaning i.e.. would it, or wouldn't it?

Also, an I right in thinking that when it comes to an oil change to use no more than 5 ½ Lts?

Hi

That run should do it, its not the speed you need, just keep it in a lower gear and keep the revs a little higher

when the DPF get blocked and regens, there's a heater inside the DPF and along with some higher revs, the higher temp generated, burns the soot off, into ash and clears the DPF

as for the oil quantity, which jaguar are you talking about

Most of my mileage is short journeys but as already said a steady 15-20 min run at approx 50 mph will clean it if the light comes on but normally it does it automatically and you don't notice it. So would not worry about it try the 3lt D XF a great car.

Cheers guys. Appreciate your help.

Joe, It will be an X Type 2.2 D.
