For tall opaque bottles (ceramic, metal), use chopstick or skewer as dipstick to measure level.
The technique:
- Keep clean chopstick or skewer near your oils
- Dip it into bottle
- Pull it out
- Read the wet mark
The read: Where is wet mark? That’s your fuel gauge.
Best for: Ceramic bottles (fancy vinegar), metal tins (fancy oil, tea), very tall bottles.
The follow-up: Mark chopstick with Sharpie at your Restock Line Formula level. Now it’s a calibrated dipstick. Dip in, if wet mark is below Sharpie line, time to buy.
