Mr Devinda_Z
Hows the Z doing these days? Hopes its doing its high octane rounds in and around Colombo in style. Its been sometime since I saw it, last was during Uni I guess... Yup, mine does ~8+ mate. I don't use synthetic oil although I can benefit from service intervals spanning 10,000 miles between services. I hardly even do half of that in a year and mostly do Colombo driving.... I hate to keep the same oil in the engine for so long as the conditions we drive are totally different to those in forums at most.... I do services between every 3500-4000 miles. Mines done 76000 milles, but thats nothing for this sort of engine as far as I know.... correct me if I am wrong....
Cheers
