Changed standard oil with the synthetic noticed more engine noise at first start-up. After my first ride, I also noticed a few new oil leaks.
Went back to the dealership and complained about what started happening, they told me the synthetic oil was designed for the newer bikes, with closer tolerances. When I went back to the standard oil, all issues were taken care of.

I have 30K miles on my 2009 Dyna Low Rider. No problems or complaints! This oil rates high in a oil comparison. Using scientific oil analysis and manufactured provided data. This product would be rated higher except Harley-Davidson did not provide the motor oils ingredients by volume. There-fore, Manufactures that did were rated higher. With high marks and one hand tied behind its back. That's good enough for me!

I have put this oil in my machine for the past 19,000 miles so far at every designated oil change interval, comes out clean every time and the engine runs like new with no oil consumption what so ever. You have to trust stock OEM oil. Price is kind of high but look at prices of all synthetic type oil.
