This is not the first time I have noticed this and I have come to the conclusion that the i30 DPF regenerates every 250 to 280 miles regardless of how you drive. Despite this hard work the DPF still felt the need for a good cough with the attendant significant effect on economy.

I had maintained a consistent high speed and the engine had been worked hard - especially at the north end of the motorway where there are a lot of inclines.

The car was heavily laden with 2 up, a lot of luggage and all the shopping management had crammed in - plus some heavy granite rocks she was bringing home for our garden rockery. After 133 miles on the motorway I noticed that the fuel consumption had increased - the DPF was regenerating 263 miles after the previous regeneration which occurred on the motorway on the way up. Traffic on the motorways was light and I was able to constantly cruise at 80 to 85 mph (128 to 136 kph). Average speed for the whole journey was thus 71 mph. It was 20.20 when we set off and 22.55 when we arrived home.
