Dont understand why they used Esso and not Tesco 99??
I was a bit baffled by this too Nath..
Although judging by the minimal differences, I very much doubt it would of been significant..
What we all wanted to see was a Stage 2+ ED35 and the same test
Think the difference would of been far greater..
So how many people on here have now had partners, parents and mates (who have no interested in cars) now saying "told ya it was a waste of money and makes no difference"
