The present invention relates to a treatment to be used as an additive to a stock lubricant. The present invention may comprise an amount of a base fluid or other fluid, such as polybutylene, naphthenic oil, or a group III base fluid and a bismuth in a non-active sulfur. The present invention formula may further comprise one or more of a defoamer, a friction modifier, a detergent, a dispersant, and a polyol ester. Bismuth may be a particularly good sacrificial material for use as a lubricant additive because it is heavy weight inorganic material that becomes soft at high temperatures. The preferred embodiment may utilize approximately 60% of the base fluid and approximately 30% of the bismuth in a non-active sulfur (approximately 15%-18% by weight bismuth) by volume. The treatment can be useful as a additive to a motor oil, a hydraulic lubricant, a gear lubricant, a diesel oil lubricant, or a compressor lubricant. |
