Why is there moisture on my car engine dipstick?

Moisture on your car engine dipstick can indicate condensation buildup, which often occurs when the engine operates at lower temperatures or short trips that don't allow it to fully heat up. It may also suggest a coolant leak, where coolant mixes with the engine oil, potentially leading to serious engine damage. Regularly check for other signs of issues, and if the moisture persists, consider having your engine inspected by a mechanic.
