# Oils and Coolant

## Engine Oil

Oil lubricates and protects the engine. Check the level regularly — ideally each time you refuel — and top up as needed.

#### How to Check

1. Park on **level ground**.
2. Locate and remove the **dipstick**.
3. Wipe it clean, reinsert, and check the oil level.
4. Follow your handbook’s advice on checking when hot or cold.

Vehicles with **automatic transmission** may have a separate dipstick for transmission fluid — check the handbook.

## Oil Changes

Change the oil and filter as recommended by the manufacturer.

- Wear gloves and wash off any oil immediately — it’s toxic.
- Store oil safely, away from children.

## Oil Use

Oil consumption varies with engine type, age, and driving style.

- Don’t run the engine below the **minimum mark**.
- Don’t fill past the **maximum mark** — it can cause leaks or damage.

If the **oil pressure warning light** comes on, stop safely and check the oil immediately.

Regular oil and filter changes keep your engine clean and efficient.

## Coolant

Modern engines use a **water–antifreeze mixture** that prevents overheating and freezing.

- Check levels frequently and top up as needed.
- Look for **high/low** markings on the header tank.
- Frequent top-ups may signal a leak — have it checked.
- Test antifreeze strength annually, ideally before winter.

**Never:**

- Remove the radiator cap while the engine is hot
- Add cold water to an overheated engine
- Overfill the system

Carry spare coolant if possible.
