Choosing the correct motor oil directly affects your engine’s performance, reliability, and lifespan. Often, drivers rely on myths or superficial criteria, such as brand or viscosity grade. In reality, it’s important to follow the manufacturer’s specifications, engine type, and usage conditions.
1. Adhering to Manufacturer Specifications: Viscosity and API/ACEA Standards
Viscosity (e.g., 5W-30, 0W-20) indicates how the oil flows at low and high temperatures. If the manufacturer recommends 5W-30, follow these guidelines to avoid engine wear. API and ACEA standards certify the oil’s performance, protecting the engine against wear and corrosion.
2. Engine Type: Gasoline or Diesel
- Gasoline engines require oils that promote clean combustion and smooth starting.
- Diesel engines need oils with additives for soot dispersion, preventing deposit buildup and protecting the diesel particulate filter (DPF).
3. Usage Conditions: Synthetic and Semi-Synthetic Oils
If you drive in urban areas or extreme conditions, synthetic or semi-synthetic oils are ideal due to their thermal stability and resistance to oxidation, ensuring efficient lubrication over the long term.
Myths to Avoid
Choosing oil solely based on viscosity or brand is not sufficient. API/ACEA specifications, manufacturer recommendations, and usage conditions are equally important. Gasoline and diesel engines have different requirements, and using the wrong oil can negatively affect engine performance.
Quick Guide to Choosing Oil
- Gasoline Vehicles: API SN or higher oils with the recommended viscosity (e.g., 5W-30). Synthetic oils are ideal for frequent starts and reduced fuel consumption.
- Diesel Vehicles: ACEA C3-certified oils that protect the DPF. Synthetic oils provide thermal stability and longer intervals between oil changes.
- Hybrid Vehicles: Oils with high standards for gasoline engines. Check the manufacturer’s manual for specific recommendations.
- Electric Vehicles: They do not require motor oil but may need lubricants for the transmission. Consult the manual for details.
Conclusion
Choosing the correct oil involves adhering to the manufacturer’s specifications, adapting to the engine type, and considering usage conditions. This ensures long-term engine performance and reliability.
