Snake oil, I suspect. I don't do a huge amount of petrol mileage but use E10 in two vehicles which are "allegedly" incompatible with it and have found no problems with either. I therefore remain skeptical about some of the claims. The Austin runs fine on it and I can't see the point in wasting money on something I don't need and that probably doesn't work anyway.
