Hi Guys, Just a few questions about the good old oil change. I'm trying to maintain an oil change every 5000km to keep my '82 air cooled microbus running smoothly. In the past I've used a filter from Steve at Mackeller VW in Brookvale, NSW which is a German made filter by the looks of things and for oil it's always been Castrol GTX 20W-50. I'm now not so close to Brookvale and was wondering if an oil filter from Autobarn, Supercheap or Repco would be just as good or should I go to the effort to get a German made filter? If so, where can I find one in Newtown, Marrickville, Inner West area in Sydney. Prefer to avoid Wolfsburg Motors in St Peters if possible (seperate 4 month old issue that has still not been resolved.) Is the Castrol Oil fine to use for this vehicle? I read a post by 1500king mentioning that Mobil 1 V-Twin is better (see http://forums.kombiclub.com/showthread.php?t=21881&highlight=oil+change) I also put an Nulon engine flush through it before changing the oil and add some Nulon Lifter Free to the new oil. Does this sound about right? Any other recommendations to keep things running smooth?
