| Dave,
Mobile 1 V-Twin full synthetic motorcycle oil. 20-50W. 100LL runs fine in the Rotary and gearbox but will shorten spark plug life.
Bobby Hughes Sent from my iPad Hello, I am new to the group. I have a Tailwind with a 13B with Tracy’s Ignition, Injection, and Redrive. I am considering using an oil from AeroShell called Sport Plus 4. It is synthetic oil with an additive for gear boxes. It is used in Rotax engines with a gear drive with a common sump same as my 13B \redrive. It also is compatible with 100LL fuel which I use. Any comments and experience would be helpful. Thanks, Dave Williams padajute@idcnet.com
