dont worry about the sulphur in fuel, at the moment its limited to 0.5% and next year, automotive fuel is dropping to 0.1%, with further decreases in either 2012 or 2015. A few years ago, the limit was 4.5%.

"There seems to be some confusion, about whether the ceramet (i.e. ceramic) coating is called Nicasil or Nikasil! I think L. N. Engineering, use the spelling Nikasil, but the text books and magazines to which I have referred, speak of Nicasil." (Posting on previous page).
Nikasil (with a "k") cylinders as used by Porsche on the 917 flat 12 around 1971, and on 911 6-cylinder models from 1974, 2.7l and later models, are:
Nikasil- (nickel-silicon carbide) layer that is electrolytically deposited inside an aluminium cylinder.
