Owners of new Alfa Romeos with the 1750tbi (GDI) engine noted the oil recommended by the dealers had changed from Selenia Star PE 5w40 ACEA C3 to this new Selenia Sport Power 5w40
ACEA C3 FIAT 9.55535-GH2 without any explanation why. What made it worse was the service bulletin circulating and warning "The use of products with different specifications than those indicated above could cause damage to the engine not covered by the warranty". There was no information on Selenia's website as to the reason or what sort of damaged Selenia Star PE had done so speculation was rife, a lot of people thought the lube was to combat turbo failures.
Anyway Selenia has finally released some info (above) and it appears the new lube is specific for direct injection applications. It holds the sole description "a fully synthetic lubricant especially designed to enhance the sporting characteristics of direct injection petrol engines(GDI)" I wonder how good really is and what they have done?
