Should Engine Oil Be Checked When Cold or Hot?
1 Answers
Most vehicle models require checking when cold. Cold and hot engine readings differ: When cold, the dipstick shows the engine's total oil capacity, while when hot it displays the amount sufficient for lubrication needs. Recommended cold checking: Always check the dipstick when cold to avoid starting the engine without oil. Hot measurements are inaccurate as splashed oil affects readings. Measurement procedure: 1. Remove dipstick and completely wipe clean with tissue 2. Note scale markings 3. Reinsert dipstick fully 4. Remove again - the oil clinging to the tip indicates current level
