Decalin for Non-Rotax?

[hamer]

I've heard a lot of Rotax pilots use it, but not much of anyone else. Considering it for my O-290.

Thoughts?

Why that instead of TCP?

Assume it has the same effect, so I'd pose the same question using TCP/Decalin interchangeably.

What is it supposed to do? It's just a bicyclic hydrocarbon. I don't see it being a lead scavenger, as is TCP.

OTOH, if you mean the stuff made by Decalin Chemicals, it contains TCP :

It's a cheaper product that doesn't use as much TCP or solvents. The lack of solvents allows you to carry it in the plane and not worry about spills. The value is similar if you compare cost, usage and effectiveness to TCP. They do work. If you use it consistently you'll get much less lead build up on spark plugs and valves. TCP is approved for use in certified a/c.
