The Rotax documentation says that an acceptable oil is any heavy duty motorcycle oil, synthetic preferred, which is designed to properly lubricate the gears.
I have 1 bottle of this oil (picture).
My question is whether is is OK to mix some of that kind of oil with the special Shell/Rotax oil that is already in my "12".
I'm not using leaded gas, just premium mogas with up to 10% ethanol. I just want to top it off, not use a lot of it. It would probably be half a pint or less added to the 3 quarts or litres minus what has been lost/used.
Along with yes or no, some reasons would be helpful.
I learned today that the Aero Shell Sport Plus 4 is currently hard to get. I bought 4 bottles today from a Rotax authorized shop who also told me they are being told to limit the sales to one case (12) per customer. Aircraft Spruce is backordered to the end of September.
