Argh. Wouldn't you think there would be SOME science to this?

If there is, it's available from Lycoming or Continental for your engine.
Not from "my A&P says...."

Well, I am blessed to have an A&P who:

1. Doesn't work on little planes cuz he needs the money.
2. Is an award-winning home builder
3. Has 40 years in the business
4. Is an accomplished pilot
5. Has rebuilt over 100 O-540s, including mine.

What he says about engines is, in my world, gospel.
