In used oil specifications, flash point should be below what degF?

Explanation:
Flash point is the temperature at which oil vapors can ignite in the presence of a flame. In used oil specifications, a minimum flash point is required to keep handling and storage safe by limiting flammability. The standard threshold used is 100 degF, meaning the oil must have a flash point of at least 100 degF. If it drops below 100 degF, it’s considered too flammable for the used oil program. Higher thresholds (120, 140, 200) would be stricter, but 100 degF is the minimum acceptable limit.
