Isn't that "six of one and half a dozen of t' other"?
The problems people are having should not be happening, but they are. They should not have to pay 15% more for fuel (is any of that cost offset by improved mpg?), but isn't it at least worth trying to see whether it helps? At least for a few tanks.
Even if you added 15% to the fuel cost for the life of the car, that may still end up being less than the alternatives. (Getting rid of the car and replacing it, lawsuit, self-financed modifications or repairs, etc.) I haven't done the calculations, but if I were in that spot I would be doing them. (I dislike dealing with lawyers about as much as I do dealing with new car service departments.)
