Hi. It is time to do the 10 hour maintenance on my new 2009 GTX. I am an engineer and a good mechanic, having worked on sports cars, boats, outboards, motorcycles, diesels, racing cars, etc for 35 years. The 10 hour stuff seemed simple, so I was planning to save $300 and do it myself, but then I saw a post that said that a dealer had to perform the 10 hour maintenance in order to satisfy the warranty. Is this true? (I'm at work and so I don't have access to my warranty at the moment.) Thanks.
