Oil Reuse Tracker
Track each batch of cooking oil and get auto-warning when you hit the maximum reuse limit. Avoid carcinogenic compounds from over-used oil.
Frequently Asked Questions
Why shouldn't I reuse cooking oil more than 3 times?▾
After 3 uses, oil oxidation produces polar compounds (>25% spoilage marker), trans fats increase, and acrolein/HNE (4-hydroxynonenal) — known carcinogens — form. This 3-use limit is set by Indonesian Ministry of Health and aligns with USDA food safety research.
How should I store used cooking oil?▾
Strain after cooling (use a filter or fine mesh). Store in airtight container, away from heat and light. Refrigeration ideal — extends life from 1 week (room temp) to ~1 month (fridge).
Can I mix new oil with used oil?▾
Not recommended. Spoilage compounds from used oil accelerate oxidation in new oil. Better to use up to 3× then discard.
How do I dispose of used oil safely?▾
DON'T pour down the drain — clogs pipes. Pour into a sealed plastic container and dispose with regular trash. Better: many cities have biodiesel/soap recycling programs.
