The other thing is US engines traditionally used much lower compression ratios. The 10.x ratio B230E in Europe is 9.x B230F in the US. That is less efficient but more knock resistant and requires lower octane protection.

On half the engines, like mine, the fix is to have two head gaskets, which at a shop would cost you an initial outlay of £500-700, and again, you'd end up with a car with 110bhp and doing 25mpg... Why not just use 98 octane? Not to mention the higher risk of head gasket failure. I know what I chose - 133bhp and 33mpg, thank-you. I'm starting to understand people reporting 240s doing 0-60 in 16s... I'd actually be curious to find out have many 240s have been converted - maybe a poll would be interesting.
