Ok and your opinion is please? (I am asking nicely now)

Complete waste of dosh IMO as no matter what oil you use it needs changing every 2.5K anyway.......just stick to good old H-D 20/50 mineral

Willy do you not think that car lube 15/40 may have been part of the reason why the oil pump gear gave up?

Oil is the life-blood of any engine. Manufacturers devote considerable time and money before deciding the right grade.
Why people then think it wise to go away from the manufacturer's specification, or use a cheap alternative (when the recommended make and grade isn't expensive), or extend the change intervals escapes me... even in an old banger of a car.
All the more so with a air-cooled Buell.
