I personally took mine to the dealer to do the 600 miles service when I had my 05 V-Star 1100. Just to make sure they had a record that the valves were checked etc. Afterward I used regular 15w40 Rotella and the bike seemed to do well. Had zero issues in 10,000 miles. There is a good V-Star 1100 riders forum over at delphiforums.com and some pretty helpful guys over there. By the way if you need some filters to do a POD setup let me know cause I have four I would let go of pretty cheap along with some oil filters left around after I sold my V-Star. They are good little bikes.
