The Owner's Manual is the best source for maintaining your new or even your relatively new "wheels". It will show you how to manage the schedule but, if you let the wrong people influence you about how often you should do this or that, I feel sorry for you.
Your service interval light will be your next indication as when you need service. Your new car should be on a warranty program to cover any malfunctioning components. If you dealer tells you that your warranty will be void if you do not follow the schedule, listen but don't be confused about what he's not saying. He's not saying that he will void your warranty if you use or don't use a particular brand. He's also not saying that driving longer than the Owner's Manual recommendation for an oil change interval will void the warranty. He wants you to think that. He's also not telling you that if there is a problem in this regard, fault has to be traced to defective engine or drive train lubricant. Sure, if your oil is black & thick as tar, you're on your own, but if the oil proves to be adequate from an oil analysis, whether it's synthetic or not, you can be sure a claim will be in on his desk. This is enough stirring the pot for now.
