Going for it.... 15,000 mile oil change interval.
BS... you don't drive over 3k a year 
Sweet 
The conspiracy theorists on the Corvetteforum who are stuck on 3k becuase it's "cheap insurance" love to say that the OEMs do this because they have a "planned obscelence" motive. They're trying to make you damage your motor so that you have to pay for more repairs


I do the truck about ever 5k miles. When I drove the car everyday, I changed it with Mobil 1 oil/filter every 2500-3000 miles. I just felt it was cheap insurance to keep an expensive motor happy. Since November when I bought the truck, I've only changed the oil in the Cobra once with Royal Purple. I've only put ~200 miles a month on it since then.

Waste of money, resources, and time.
