I have just got myself a mk3 (2001 Y with 44k on the clock) seat ibiza cupra T (156bhp), I am geting the car serviced tomorrow and was wondering what is the best oil to use for the service? I am also getting the gearbox oil changed aswell, any ideas on the best gearbox oil for this car? The sparkplugs are also geting changed, I will in the future be geting this car revo'd or remapped, is it worth getting higher heat grade plugs for the higher boost etc? Any advise (particurlary on the engine oil type) would be a great help.
