As I understand it, the nikasil was attaked by the higer sulphur fuels found in the US. But I believe we use lower sulphur fuels now so it shouldn't be a problem. Interesting reading if you google nikasil with bmw or jaguar. Lots of engine failures credited to that stuff, but it may not be an issue now if we don't have sulphur in the fuel anymore.

You're right, BMW and Jag did have issues with it. But, not all applications did, so there must have been something peculiar to the way the Nikasil was formulated or applied by BMW and Jaguar to cause the problem.
Ferrari and Lotus used Nikasil liners in their engines as far back as 1983. And while they each have their own issues, quirks, failings, or what not, the Nikasil coated liners were never one of them. Nikasil is also very popular with many Motorcycle engine Mfrs., they too didn't have issues with them either.
From what I understand, Nikasil is a much more proven technology than Lokasil. At least, I'm a little more comfortable with it.
