As some of you might remember I rebuilt a 1981 GL1100 Triwing trike for my son. He now has about 2000 miles on this oil change and we are wondering how often do you change your oil and filter. The manual says once a year /8000 miles but that sure seems like a lot of miles.And are there any brands of oil he should stay away from in his wing. Thanks John
