Engine oil changes are one of the most important maintenance tasks for ensuring an engine's performance and lifespan. However, one of the most frequent questions among drivers is: how often should I change the oil? The answer depends on the type of lubricant, driving conditions, and manufacturer recommendations.
Why is changing engine oil so important?
Engine oil performs essential functions:
- Lubricates moving parts to reduce wear.
- Dissipates heat generated by combustion.
- Cleans the engine by keeping impurities and residues in suspension.
- Protects against corrosion and oxidation.
- Helps improve fuel efficiency.
Over time, the lubricant loses its properties due to contamination, oxidation, and high temperatures. When this happens, the engine begins to suffer accelerated wear, which can result in costly repairs.
How many kilometers before it should be changed?
Although the manufacturer's manual should always be followed, these are general guidelines:
Mineral oil
- Recommended interval: 5,000 to 7,000 km
- Ideal for conventionally used vehicles and older generation engines.
Semi-synthetic oil
- Recommended interval: 7,500 to 10,000 km
- Offers greater protection and thermal stability than mineral oil.
100% synthetic oil
- Recommended interval: 10,000 to 15,000 km, depending on the manufacturer and usage conditions.
- Provides the best protection against wear, oxidation, and extreme temperatures.
Factors that can reduce oil life
It is advisable to shorten oil change intervals if the vehicle operates under severe conditions such as:
- Heavy traffic with frequent stops.
- Short trips where the engine does not reach its ideal temperature.
- Towing heavy loads.
- Off-road driving.
- Dusty environments.
- Extremely hot or humid climates.
In tropical countries like Panama, where high temperatures and humidity prevail, it is especially important to use a quality lubricant and adhere to maintenance intervals.
Signs that the oil needs changing
In addition to mileage, pay attention to these signs:
- The oil is very dark and thick.
- The oil pressure light comes on.
- The engine makes more noise than usual.
- A loss of power is perceived.
- Fuel consumption increases.
- The vehicle has exceeded the recommended time since the last change, even if it hasn't traveled many kilometers.
Which oil to choose?
Selecting the correct lubricant depends on the vehicle manufacturer's specifications. Using oil with the appropriate viscosity and certifications ensures:
- Greater engine protection.
- Less wear.
- Better fuel economy.
- Longer lifespan for the emissions system.
- Better performance at high and low temperatures.
The TotalEnergies QUARTZ, TERPEL Lubricantes lines, and other recognized brands offer solutions for modern and high-mileage engines, complying with international specifications such as API, ACEA, and ILSAC.
Changing the filter is also important
It is always recommended to replace the oil filter whenever an oil change is performed. A saturated filter can reduce lubricant flow and allow contaminating particles to circulate within the engine.
