I'm pretty much convinced that Schaeffer's would be best for me. My next change at the dealer's will be next week at 20K. That means that I have 16K to go on the warranty. Does it sound like a plan to let the dealer change it at 25K and then start with synthetic at 30K? I'll be out of the warranty in half the planned OCI with the synthetic. Also does it make any sense to put in a rinse cycle of regular for about 500-1k miles before the synthetic? I'm not inclined to do that since part of the reason to go to syn. is to limit my trips under the car. Although I keep referring to synthetic, I'm convinced that Schaeffer 9000 5W30 is the way to go and will probably be ordering by next spring.
Thanks again for all the help!
