Here is the question I posed to Havoline and their answer:
Thank you for your inquiry. I do not recommend Havoline 20W50 for use in a motorcycle. We do not make a motorcycle oil in either the Chevron or Texaco line.

Subject: Havoline 20-50 oil
I installed Havoline 20-50 oil in my new Harley Davidson Road King (2006). Now I am having some doubts. HD requires that the oil have a diesel rating - does this oil have such a rating? What is it?
Second question: is there a Havoline 20-50 that says "Motorcycle Oil" on the label or is it the 20-50 I bought at Auto Zone that makes no reference to motorcycles?
Thanks!
Any comments about this reply? Havoline did not reveal the rating of the 20-50 - do any of you know what they are?
