Ok heres the deal I feel Ams oil The best by far but cost. I run that in my wife 06 K-9. I have a 04 bull dog I.m running Valoline synethetic. I thought about running Mobil one synthectic but cost more. But I really think Valoline is a better oil would do you think? I did just installed that FLO oil filter on the 04 bull dog That is one trick filter. If you plan to keep your bike get one saves you 15 bucks every oil change.Plus you get better filtering and get to see what your oil looks like also has a magnetic in it. Pretty cool.:flag: Thanks Buster
