For builders that will soon be choosing a suitable oil for their Rotax, you might be interested to know that Van's is using AeroShell Oil Sport Plus 4 in the prototype. This is specifically formulated for 4 cycle Rotax engines and enables owners to use Mogas and/or 100LL.
The oil comes in liters, rather than quarts. A 12 liter case is available in the Portland market for $102.13. On line you will find it priced about $84/case plus shipping that will probably bring the delivered cost to over $100.
