Yesterday, I spoke with the service manager of the largest Subaru dealer in the country. I asked him about oil types and the frequency of changes. His response was: 1. Changes of oil and filter are required every 3,500 miles. 2. Only one deisel/turbo oil (made by Titan) is recommended. 3. Synthetic oils like Mobil 1 and AMS/OIL should not be used. So far, the nice people on this newsgroup have explained to me that SF type oils are more than adequate, changes should be made at 2,000 mile intervals as cheap insurance, and that filters at discount stores are as good as any since they're all made by the same people. One person also recommended a FRANZ (sp?) filter in the system after initial break in. I have resigned myself to the fact that I must change the oil and filter more often than non-turbo vehicles. What I don't anderstand is why AMS/OIL and SF oils cannot be used. Any help? Phil Rastocny
