I've used RACE before. as any fully synthetics they basically act the same. just remember it all depends on how you run your engine. never push your engine oil to the limit. if the package says that it could last up to 15,000 km change it at 10k km., if it says up to 7.5k km change it at 5k km. get my point? always give an allowance because of the tropical climate and the dust in the streets.
