Jens,

When I was actually working for a living, I ran an industrial supply store. We sold lubricants for industry, gear oil and also greases. We had a product that you added to any oil that improved the EP rating. They had a demonstration device similar to what you have described. Unfortunately, this was not meant for two stroke application.

But what if someone tried this or a similar additive? I knew what it was back then but memory fades. Anyone know what that might be?

On the gasser thread, there's much discussion about oils and some swear by Amsoil's claim of 100/1 mix for their synthetic. Others trash the notion. That is, of course with a rod with bearings. Still, if 1% works on them, might it not be robust enough to work for our bushed rods at 5% ?
