Yes, manufacturer recommendations for specs and change intervals are usually good enough to get a vehicle past the warranty period. But they aren't gospel and they aren't the best plan if you like mechanical things and want to treat them right - especially if you like to run them hard.

You can't change lubes too often (after break-in). The worst you are going to do is waste a little money and you might end up saving a critical part. When in doubt, change it.
