This is my first post, bear with me.
I have a 912UL.
I find searching for the latest SI confusing. I believe the most recent oil type Rotax SI is SI-912-016R8, dated 16 Apr 2015, please correct me if there's one more recent. It appears to state that now the only oil Rotax recommends is Aeroshell Sport Plus 4, all other oils have been dropped. Is this correct? Am I missing anything?
