I have a 45 ALC on another character and every time I try to craft shark oil im getting the message about how I need advanced support from the guild. Sure enough, I fail this synth alot without the advanced support. Im only getting 100 sp per craft from this item, which indicates that its well below my level - I have been making it since level 35 as well. Also, the databases online indicate its a level 35 synth. I think this is bugged.
