Thanks for your reply.
Cannot remember the brand of oil filter. Went looking for a Ryco Z9 but none in stock, so picked up a filter, blue in colour, come to think of it, it did have no-frills packaging.(white box, blue writing, made in Korea or somewere like that)
Do you have a recomendation for Oil Filter brand?
With regards to the engine flush, I checked the dipstick before change. The oil was darker than normal but not bad. After the flush out the oil was totaly black. I am amazed how much varnish and other contaminates can build up in 10,000 K's.
Your right, its probaly not required to be done evrey 10K, but its just something I prefer to do.
