Hello! So in spite of the lockdown I have now managed my 1500 km run in over the last month and am looking forward to increasing the revs a bit. Sorry if what I am about to ask is a daft question. I have both the service manual and the owners manual. Both refer to 'Oil Filter Change' as a 'C' at the first service and then 60,000 km. This is in addition to 'Engine Oil Filter' as a 'R' at every service. So even I understand 'Replace the engine oil filtet' but what is 'Oil filter Change' as a 'Clean'? Neither manual explains this line but both insist on it. I am thinking mesh filter, is this what it means and so does the sump have to be dropped? Ta for looking.
