“How can you tell if an oil has exceeded the appropriate temperature range?”
Lubricants are formulated with base oils and additives to function under the conditions expected for the intended application in terms of speed, load, temperature, oil change interval, etc. These formulas may be designed for compressors, turbines, engines, gearboxes, etc. When their properties or performance are diminished as a result of contamination, temperature changes or additive depletion, the lubricants must be modified.
