75W-90 - Shell Helix RGO when it was Shell - current spec needs double checking given it's no longer Shell generally e.g. back to Silkolene in the engine, Sunoco in the petrol tank.
Another question for you all please, is a K7 1300 OK to run on an ethanol blend fuel? BP is running out of standard 98 here in NZ and a Mobil blend is the only other 98 option.
