Ask a Technician: Why is the oil fill line important on a fryer?

The oil fill line on a fryer allows you to keep the oil level consistent so you can produce the best food possible while maintaining user safety. If the oil level is too low, it exposes the burner tubes, which causes the vat to overheat and crack. By contrast, if the oil level is too high, hot oil can spill over, resulting in injuries and damage.
