The last video was fun to watch and made me think "... I AM that fool..." when filling up with Aral (BP) Ultimate the other day.

Then I started thinking: does the diesel TT has a dpf?
Or an EGR?
Any valve in the exhaust system?

Sure, their numbers don't lie.
Did they mention in the video (I have to admit I skipped to the results after 5 minutes or so) they tuned their racing ECU to the different fuels?
Maybe they could have gotten a few HP more out of a retune with V-power?

On my 3.6TDV8 I once had a leaking intercooler-to-intake-tube, to fix it I went to a RR dealership in the Netherlands as I was visiting my parents, they had the part on stock.
They tested the EGR valves too and the on screen values showed they were in perfect condition, IIRC it was the closing speed or something like that.
As the mechanic and I were talking I mentioned I only used the Ultimate fuels while I owned it and according to him those Ultimate fuels DO keep EGR valves cleaner. 2012 4.4TDV8
