I got a nice Craftsman professional MC lift/jack for my birthday and am getting ready to change my oil. This got me to thinking...they always say you should change the oil in your car every 3 months or 3,000 miles. I have put about 1100 miles on my bike since l bought it 5 months ago. Should l have changed the oil a couple of months ago even though the mileage hadn't been put on it? Also, does anyone have a strong recommendation for a brand of oils they like? My owner's manual says to use SF/SG or SH/SJ in API, MA in JASO.
