I run mobil one 10w-30, pricey(about $65 for 5 litres) but the best going around, air filter, you can use k & n, i just use holdens standard filter.
Spark plugs either ngk or bosch.
they're the ones i run, the oil is better purchased in a 20 litre drum as you need 7 litres per service, this will bring the cost done to $50 per 5 litres.
Hope this helps.
