Hi Rob, Aero oils are a deffinate NO for Limbach engines.
The clearances and tollerances in Lycoming etc. are massive compared to Limbach - automotive derived.

It wrecks catalytic converters and has become less useful in modern motors so is being reduced in modern auto oils. I'm think of switching to an aero oil (possibly shell http://www.shell.com/home/content/aviation/products/lubricants/piston_engine_oils/ ) Has anyone got any recommendations?
