volvo 1.8 GDI engine fuel query - Thicko2
I have recently picked up a volvo s40 GDI at auction (see new car advice thread). www.honestjohn.co.uk/forum/post/index.htm?t=21008

In honestjohn\'s car by car breakdon he notes that this engine is designed for 98 ron unleaded and faults have occurred wehere cars have used lower standard octane rated fuel.

Could anyone explain this in more detail, the guide book and sticker in the filler cap says use 95 octane unleaded.

Many thanks.
