Oil change - will this cause issues?

[PieEater]

Interesting article Mike, I never knew that the fully synthetic oil I was buying was in fact mineral oil, or that a 10-40w semi-synth is essentially knackered by 1500 miles. My take on the article though is it appears quite definite in confirming the commonly held belief that using a cheap car oil in your motorcycle is not a good idea, and outlines a number of reasons for this.
