Spot on. Porsche knows their own engines, if they can design a great car then give them credit that they know what they are talking about.
<blockquote id="quote">No way. Can you imagine what would happen to Porsche's reputation if all of their engines started dying prematurely because of their recommended maintenance? Porsche's success depends heavily on their ability to continue making cars that last. There are 911SC's and Carreras from the '80s that have gone 250,000+ miles without needing a rebuild, simply by following the recommended oil changes at 15,000 miles or 1 year. The 928's V8 enginewas built for even more longevity - it is not uncommon for them to go 400,000+ miles before rebuilding, following the same maintenance schedule.</blockquote>
Nothing wrong with changing oil more often than needed, except that you are wasting money. Porsche is not pulling anyone's leg - follow the maintenance schedule in the book that came with your car. Porsche does countless hours of testing of their engines 24/7. The maintenance schedule that they recommend is a result of their exhaustive tests. Believe me, they know what they're doing.
