What oil is best for a gasoline engine?
For gasoline engines, synthetic oils with viscosity grades like 5W-30 or 5W-40 are often the best choice. They provide strong protection across different temperatures and ensure optimal performance. Always check your manufacturer’s specifications (API, ACEA) and any OEM requirements for your vehicle model to select the right oil.
What oil is best for a diesel engine?
For diesel engines, synthetic 5W-30 or 5W-40 oils are commonly recommended, offering reliable protection in both low and high temperatures. Be sure to verify ACEA standards (e.g., ACEA C3) and OEM specifications such as VW 507.00 or MB 229.51 to ensure the best protection and long-lasting engine health.
Choosing the right engine oil
Selecting the correct engine oil is essential for both performance and longevity. Engine oil protects against wear, keeps the engine clean, and helps regulate temperature. Here are the key factors to consider:
Viscosity
5W-30: versatile, ideal for modern engines, protects in all seasons.
5W-40: suitable for heavily used engines, strong high-temperature protection.
10W-40: recommended for older vehicles with higher mileage.
Industry Standards
Look for approvals such as API, ACEA, or specific OEM standards (e.g., VW 504.00, BMW LL-04, MB 229.5).
Oil Type
Synthetic oil: best for modern engines, maximum protection and durability.
Semi-synthetic oil: a balanced option for older generations of cars.
Mineral oil: suitable for older, less demanding engines.
Driving Conditions
If you drive in tough conditions (city traffic, frequent short trips, or long highway journeys), synthetic oil is the most reliable choice thanks to its resistance to heat and degradation.
