Compression question for the tech heads.
What is the compression ratio on the LR Zetec 2.0 litre engine? The reason I ask, is that I think I saw somewhere that the US engine has a lower compression, and I want to compare (possibly right because they have lower octane fuel) In the US, McNews recommends skimming the FR Head by 040 to raise the compression, but if we already have higher compression, i could end up stuffing up the lot

I think it's 10.0:1 to be precise. Same compression for the 96kw rated engine too. BTW I still can't understand why there wasn't just one i.e. 96kw rated engine in the entire range of LR Focus. But anyway, that's ancient history now.
