I wouldn't recommend it. You don't have to use "Harley" oil but you should use a V twin formulated motorcycle oil. If I remember correctly, my book says to use a "Diesel Compatible" in an emergency, i.e., you're in a pinch on the road. You need to remember that your HD is not just air cooled, but oil cooled. The correct weight V Twin motorcycle oil is formulated to not just lubricate, but cool your motor.
Some one needs to put the harley manual down!!!!!! Please!!!!
Use what ever motor oil you want. As long as the weight is correct for the outside temps. you ride in. Try typing in oil in the forum search. You'll find about a few million forums on oil and weights and who uses what. I have ran Kendall in all my bikes.
Look out here comes another oil thred!!!!!!!!!!
