New fuel standard for 912iS?
Rotax issued a new Service Bullitin for fluids.
As I recall the previous fuel standard for MOGAS was 91 AKI for the 912 iS Sport. (U.S. standard)
The new standard for the 912iS (Sport) is 87 AKI. (U.S. standard)
The standard for the 912 ULS is still 91 AKI. (U.S. standard)
