Just some more information regarding oil changes. I just changed my oil after my ride to the Panama Canal and another 800 miles to my house in North Carolina. So, all together 10,600 miles. In all of my IBR's ( 5 ) I did not change the oil until I got back home and the shortest IBR ride was 11,800 miles and the longest was 15,000 miles. I rode to Alaska and back from Key West, 14,000 miles and I have done many 8,000+ mile rides and not changed my oil until I get back home. I send my oil to Blackstone labs and the last time they said my oil looks good and I could go at least 12,000 miles if not more.
I have done this on my Gold Wings, FJR, RT and GSA's.
