BenR.....hes got a 1.6 16v mate, not a valver
i would have suggested going for the motorsport version if it had been a proper 16v.....
though i still reckon you cant go wrong with 5W-40, i mean the Cup race cars use it (Elf), as do lots of other race cars, the Peugeot team uses 5W-40 Total stuff......
