Rate Automatic Oil

Hello! I ask you, since you as Ami fans should naturally have more experience with automatic drives (in the Mazda forum the reactions were so far rather economical): How do I recognize that the oil should be renewed? I know that it shouldn’t smell burned, but how smells burned? It’s about a Mazda Premacy, the oil is light brown-orange-transparent and smells sweetish-resin-like. Does that sound ok or what do you mean? That might come over a bit clumsy now but I don’t know. I don’t have any experience with vending machines so far and just want to make sure that my father’s car is not worn out during the inspection, he relies completely on his car dealership and I want to keep a watchful eye on it. Machines are unfortunately treated a little stepmotherly here in the land of the nervous gas foot… Greeting, Rapidski (with the Baguette Suburban aka Renault Rapid)
