most 900 owners here go 3,000 miles from what i read.
How many miles between oil changes in my bike? 06 900 classic.
I had a Ford Ranger that went 215,000 before being totaled by the insurance company after a minor fender bender. Starting at 40,000, used Mobile 1 and changed the oil every 10,000-11,000.If I'm not mistaken, the manual says every 7,500miles after the initial 600mile service, but I don't go over 3000miles on any vehicle I own. I had a Ford zx2 and a Ford escort GT that both went easily over 200,000mile with no major problems due to changing oil frequently. Hope this helps.
