Can anyone advise me how I safely get out of this. I've inadverently added about a cupful of synthetic engine oil (5W40) to the PAS system. I haven't turned the engine over since doing this yesterday. Thought I might drain the PAS system and flush through with PAS mineral oil but I can't find what spec. of oil to put in. Halfords say 'refer to service manual', service manual says nothing. Can anyone help?
