There probably isn't a hotter topic at any level of auto interest.
My answer to all questions about brands, viscosity, service interval, etc., is to point out that we see absolutely no oil related failures in modern engines using almost any service plan.
I hate to say this but you are probably only maintaining that car for future owners, because as a new car owner it is VERY, VERY unlikely that you will have the car till any of this matters (let alone 100,000 miles).
The current service problems we see are from cars traded at the end of warrantee by people who did at best the ridiculous intervals mandated by the marketing people.
