The early E38s with the M60 engine had it coated with a substance called Nikasil (Nickel based). It was found in sulphur rich petrol environments, premature wear occured on the cylinder walls - leading to reduced compression. This problem was predominantly in the US (and some in the UK). To resolve this BMW began coating with an aluminium derived substance called Alusil.Now to the heart of the matter in Malaysian E38s, the Nikasil material was originally chosen as a superior material to Alusil, but because of problem in the US, Alusil was used in post 96 cars. I have spoken to the AutoBav people and they told me that the Nikasil premature wear problem did not affect Malaysian E38s as our petrol was OK.In any case the 94-96 E38 here would already show signs by now after 13-15 years by having low compression, but that hasn't been found to be the case - most Nikasil engines are still running strong. So it a problem which DOESN'T affects us here in Msia.Just FYI</blockquote>
