What’s your Cylinder Index? It’s a term invented by radio broadcaster Joe Soucheray. To figure it, simply count the total number of cylinders in all the internal comubustion engines you own. So I get a V8 in the Dakar, another one in the Rangie, the wife’s car has a 4 cylinder engine, and I’ve got a generator. That makes 21 my my reckoning. Anyone in the UK doing better?
