Fuel fable

I write in regard to Robert Fryer’s letter, ’Pogue’s go-trick’ (The Engineer, 8 March).

As an engineer in the auto-motive industry, I’m not sure whether to laugh or cry that this urban legend/conspiracy theory is still being banded around by supposedly intelligent members of the engineering community.

There is no truth to this myth that I have heard told many times but always with varying details and a local twist. The most recent was that it was a man in Scotland in the 1970s who achieved 200mpg in a standard car using a ’special fuel system’ that he had invented – which was then bought and covered up by the oil companies.

I’ve also heard the same story set in the 1950s in Germany with BMW and Mercedes being the conspirators.
