Don't use the Screaming Eagle. This oil is made by Sunco. Harley doesn't manufacture Oil. So Sunco was the cheapest oil that would let Harley tack their name on. I haven't changed the Oil on my RoadGlide Ultra yet as I just bought two weeks ago - used.
I have changed the oil on my 02 Heritage Softail myself and use Mobil1 V-Twin 20W-50 4-Cycle Motorcycle Oil (1 qt.)
