337 Oil Diluters.

[Paul462]

Actually, come to think of it, diluting oil at engine start sounds like an awful idea - like they say, "The worst thing you can do to your engine is to start it...", because there's no real lubrication during the first few strokes, and those first few strokes account for something like 80% - 90% of cylinder/piston wear, from some figures I've read. For this reason, it's not recommended to pull the prop through by hand a few turns prior to starting, because this wipes off what little oil remains on the cylinder bores from the previous run, consequently increasing wear even further during engine start.

So to preserve cylinder/piston life, it sounds like a good idea to never use the oil dilution feature unless one REALLY needs it for cold starts. Any thoughts? Does one ever REALLY need it?
