Personally I would just make sure the engine is well warmed up and then drain the oil out. Let it drain for around 15 mins and you will get nearly all of the old oil out. Then just fill up with new. Flushing oil can cause problems.XTnet said:Thanks Milton I shall get some.
As I do not know what the previous owner used, would you suggest a flush oil then refill with the Millers? Of course I woul also be fitting a new filter at the same time.
