When you rent a car, it’s important to understand what engine oil is and when it should be changed. Let’s take a closer look. Engine oil is a lubricant that forms a protective film between the metal components inside an engine. It reduces friction and wear, especially during engine startup. Additionally, engine oil has many other benefits, such as:
- Heat Dissipation: Helps cool engine components.
- Rust and Corrosion Prevention: Protects metal parts from rust and corrosion.
- Cleaning: Prevents the buildup of sludge, dirt, and metal particles that can clog engine parts.
- Oxidation Prevention: Maintains oil quality by preventing oxidation.
If the oil becomes too thick or too thin, it cannot circulate effectively, reducing its ability to lubricate the engine properly.
Types of Engine Oil
There are 3 types of engine oil available in the market, each with its own characteristics:
1. Conventional Oil (Mineral Oil)
- Made from refined petroleum.
- Suitable for use for about 3,000-5,000 kilometers.
- Lasts approximately 6 months.
- The most affordable type of engine oil.
2. Semi-Synthetic Oil
- A blend of conventional oil and synthetic additives.
- Suitable for use for about 7,000 kilometers.
- Lasts approximately 6-9 months.
- Moderately priced, between conventional and fully synthetic oils.
3. Fully Synthetic Oil
- Made from 100% synthetic compounds.
- Suitable for use for about 10,000-15,000 kilometers.
- Lasts approximately 1 year.
- The most expensive type of engine oil.
When Should Engine Oil Be Changed?
The best practice is to follow the vehicle’s manual for specific guidelines. However, general recommendations are as follows:
1. Based on Mileage:
- Conventional Oil: Change every 7,000-7,500 kilometers.
- Semi-Synthetic Oil: Change every 10,000-15,000 kilometers.
- Fully Synthetic Oil: Change every 15,000-20,000 kilometers.
2. Based on Time:
- If you don’t drive often, change the oil every 6 months to 1 year, even if the mileage hasn’t been reached.
3. Based on Usage:
- Frequent driving or heavy loads may require more frequent oil changes.
- City driving or stop-and-go traffic may also necessitate earlier oil changes.
4. Observe Signs:
- If the oil appears dirty, has a burnt smell, or the oil level drops unusually, change it immediately.
