Frequently Asked Questions
How often should fryer oil be changed?
Most commercial fryers need oil changed every 4-8 batches depending on what's being fried and at what temperature; heavily breaded items degrade oil faster.
What does the top-off percentage mean?
It represents the amount of oil lost to absorption and evaporation between full changes, which you top off to maintain fryer capacity.
Does oil type affect the cost calculation?
Yes, just update the cost per quart field to match your specific oil (peanut, canola, vegetable) since prices vary significantly.
