If so it seems like a lot... Is it normal? Can't be doing it any good surely? Would it do this at such a low mileage? I only use esso or BP fuel in it so it ought to be reasonably clean anyway

I don't think anyone really really knows if its ok to have diesel in the oil .. seems a lot of cars do it if its start stop short trips .
we had a lot of Vauxhall vans in for engines because of it , but that was blamed on not stopping when oil too high light came on so level kept rising years ago if someone said " here is a litre of diesel now go and put that in with your oil " you would have told them to @@@@ off but it seems ok to do it now!!!! people will say just change the oil , but that's no joke with the price of oil for dpf equipped car autodata state low ash oil must be used in dpf equipped defender |

it's definitely NOT ok to have diesel in the oil
high probability this is an injector leaking/loose, fuel dilution can do some bearing damage if not taken care of right away. worst case scenario your engine will go bang have it fixed asap! -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged Defender Puma Workshop Manual: https://bit.ly/2zZ1en9 Discovery 4 Workshop Manual: https://bit.ly/2zXrtKO Range Rover/Sport L320/L322/L494 Workshop Manual: https://bit.ly/2zc58JQ |

autodata state on some cars to leave oil on lower mark to allow for diesel going into oil!
that's why some cars have oil level sensors now because of this |

According to the MY12 workshop manual, active DPF regeneration typically occurs every 250 miles, takes up to 20 minutes and will increase fuel consumption by 100%. Unless you are getting the amber DPF warning light, it seems unlikely that DPF regeneration is going to increase your oil level so dramatically.
The Defender is the first DPF equipped car that I've owned that I have not been able to feel when it is doing a DPF regeneration; apart from the odd whiff of hot exhaust and noticing the fuel level drop a notch on a long run. 250 miles is very frequent and maybe this means they can keep it short and sweet. Is there a high pressure fuel pump somewhere on the block? These are problematic on BMW engines, where a failed seal will fill the sump with diesel. |

Thank you all for the comments, I don't do many short runs in it, most are 30-50 mile minimums in each direction with 150-300 mile run every few weeks. I'm not sure if it has a high pressure fuel pump on the block anywhere. My old TD5 had a problem with the injector seals that caused the sump to fill up with diesel and that got the garage I was using fairly excited so I assumed this is not an ideal situation...

Now I'm getting concerned!
My commute is 6 miles each way. Are these short trips likely to cause damage? |

Not damage but more frequent active regeneration with it's consequent side effects of increased fuel consumption and oil dilution. |
