My Saab dealer charges $89 for an oil & filter change (they also check the belts, hoses, lube hinges, etc.) and use 0W-40 Mobil synthetic. Costco will do an oil and filter change for $39 but use 5W-50 Castrol GTX synthetic. The owner's manual recommends Saab Genuine or Mobil synthetic 0W-30, 5W-30 or 0W-40. Think it's ok to go with Costco for my oil changes? Obviously, I'd like to save $50 per oil change. Thanks for your input George
