That's insane. You run the factory oil for 6705 miles, then install better oil and change it in 300 miles. You would have been much better to dump the factory oil at 300 miles then run the next oil 6700 miles.
Actually I was gonna follow the OLM, thats why I went so far on the 1st change. I got cold feet and couldnt do it. I just figured I'd rinse it with such a short OCI. Now regular 3k OCI's...done
