two stroke oils - anti corrosion additives ?

[Gerry45]

Does anyone know what kind of anti-corrosion additives are used in two stroke oils, if at all ? Unfortunately this is a subject which the manufacturers are reluctant to discuss openly.

Ive recently compared the ability of a few oils to prevent corrosion and find it varies significantly between the products. The best seemed to be an oil that was formulated for extreme high speeds and temperatures!

The Lubrizol corporation has a lot of online literature regarding oil additives. The following link will point you close to, if not exactly where, you need to look.
