From Lawrie O'Connor
A $200 gadget to give a 19 per cent boost to engine efficiency (4 October, p 23)? I can’t believe it, and if they reduced the claim to 5 per cent I would still be a sceptic. If it only gives a reliable 1 per cent improvement competition will ensure that it is fitted as standard in every new car, with garages everywhere specialising in retro-fitting the magic kit. If I am wrong I will give a grovelling apology a year from today – but I am not holding my breath.
