I have a question for you guys. My buddy's dad is getting up in age, and has some health problems, which limit his riding. He doesn't want to give it up but he only rides about 2,000 miles a year. He uses Mobil One V-Twin in his Road King, and changed it last fall. He's wondering, since he only expects to have about 2200 miles on the oil, if he needs to change it this fall, or will it be ok to just leave it in all winter, ride on it next summer, then change it with about 5,000 miles on the oil. However, it will have been in the bike for two years. What do you think?
