Here's why:
* 30W oil is a blend: It's a mixture of different hydrocarbons, each with its own boiling point. The "30W" designation refers to its viscosity (thickness) at a specific temperature, not its chemical composition.
* Viscosity changes: Even within the same 30W oil blend, the viscosity changes with temperature. So, the boiling point would depend on which specific hydrocarbons are present and their relative proportions.
Instead of a boiling point, you can look at the following:
* Flash point: This is the temperature at which the oil gives off enough flammable vapors to ignite.
* Fire point: This is the temperature at which the oil will sustain combustion.
* Pour point: This is the lowest temperature at which the oil will still flow.
These characteristics are more relevant for understanding the safety and performance of 30W oil.
Remember: Always refer to the specific product information provided by the manufacturer for accurate data on flash point, fire point, and pour point of your 30W oil.
