Ask any technician the reason that almost all cars need major engine work is lack of service(oil changes). Now do you really believe that the oil has improved so much in the last 2 years that engines can really go twice as many miles?? I guess that 5-6 years from now we will know what the results of the extended oil service intervals will be.
