How long does it take for engine oil to fully settle after parking?

[Jayla]

For the oil attached to the surface of engine components to completely settle into the oil pan, it typically takes more than 20 minutes after parking. 1. Correct measurement method: In the morning when the engine is cold, pull out the dipstick, wipe it clean with a tissue, then reinsert it. After pulling it out again, check both sides of the dipstick (to prevent one side from being affected by oil on the tube wall) and use the lowest reading from both sides as the accurate level. It's best to measure multiple times for an accurate result. 2. Adding oil: If the oil level is insufficient, it will affect normal engine lubrication, increase wear, and consequently impact engine performance and lifespan, requiring timely replenishment. When the engine is warm, the oil flows better, making it easier to add, but be cautious about the amount added.
