Please help me understand this. If you have a warranty and you don't change your oil at a warranty approved place, the warranty is invalid? Does this relate to just the engine or any warranty work on any part of the vehicle? A receipt showing an oil filter & oil from an auto store is not enough proof?
Personally I would probably take the chance and do it myself and use a high quality oil & filter, especially if I am planning on keeping a car past warranty.
