  1. Add oil until it covers the whole dipstick
  2. Add oil up to Full, but do not overfill ✔
  3. Do nothing until the oil light comes on

Why: A Kia manual says if oil is near or at L (Low), add enough oil to bring the level to F (Full). Do not overfill.

Huh, didn't know that: On that Kia dipstick, the safe zone between L and F is called the C range.

The dad joke
I need to fill my oil but can only find the 710 cap. You know, 710 = OIL upside down.
