At first blush this sounds good, especially to someone dreaming of a Golf TDI GT Sport. But on reflection it raises more questions than it answers, eg what about Japanese diesels sold in Europe, eg Accord Euro, Mazda 3 & 6 etc? The Mazda engine particularly is supposedly the same as the Focus & Mondeo TDCi unit, and is possibly sourced from Peugeot... So these engines should be Bio-compatible?
And thinking again of the VW twin-cam diesel, it doesn't actually use a common rail. IIRC each injector has its own pump driven off the inlet camshaft. Any idea how it would go with Bio?
