I go with synthetic because it is much more resistant to "shearing". My rule of thumb is to change synthetic at twice the interval of dino oil. Even then, it is generally in better shape (retains more lubrication ability)than dino oil at half the mileage. In my truck, I changed dino oil every 2,000 miles; with synthetic, every 4,000. Yes, this is more frequent than recommended, but changing oil more frequently extends engine life and beats rebuilding an engine!
Since synthetic runs about twice what dino does, the cost is about the same and I save the price of a filter (truck and other bike) and the time it takes to do a change.
Guba is right!
I'm keepin' all the left over parts. I'm gonna use 'em to build another bike!
