The Maximum Duration for Changing Car Oil: Your Guide to Maintaining a Perfect Engine

• 6 min reading time

The maximum duration for changing car oil is something every vehicle owner should know, regardless of the type of car they own. This step is crucial for maintaining engine health and keeping your vehicle in excellent condition. Monitoring your engine oil and changing it at the right time is essential, as forgetting or neglecting this can have serious consequences for your car’s safety. If you want to learn more about the importance of this process and when to change the oil—whether for new or old cars—keep reading with Tollmart to discover the maximum duration for changing car oil and other valuable information.

Importance of Changing Car Oil

Your car always requires care and maintenance. Part of this responsibility is regularly changing the engine oil to keep it running efficiently. But why is this step necessary?

Here are some key reasons why you should change your car’s oil and adhere to the maximum duration for changing car oil:

• Regular oil changes maintain engine performance, protect it from damage and wear, improve efficiency, and extend its lifespan.
• Oil changes remove accumulated impurities inside the engine, enhancing its ability to function at peak performance.
• Replacing engine oil ensures smooth vehicle operation and reduces frequent malfunctions, saving time and effort spent at maintenance centers.
• Reduces maintenance costs—regular oil changes protect the engine from damage, preventing costly repairs.

The Maximum Duration for Changing Car Oil

Some believe that engine oil should be changed every six months, which is a good rule of thumb. The recommended oil change interval ranges between 3 to 6 months.

Alternatively, the appropriate timing can be determined based on mileage, typically every 5,000 – 7,500 kilometers.

However, several factors influence this decision, including engine type, driving conditions, and road quality.

Signs That Indicate It's Time to Change Car Oil

How can you tell if your car needs an oil change?

There are several warning signs that indicate it's time to replace the engine oil:

• Frequent long-distance driving requires shorter oil change intervals to prevent engine issues.
• Abnormal oil consumption—if your engine oil level drops quickly, there may be a leak or other issue.
• Dashboard warning light—some vehicles have an oil change indicator that lights up when oil levels are low.
• Unusual engine noise—if you hear squeaking or abnormal sounds, your engine might be suffering from oil deficiency or deterioration.
• Burning smell—if you detect an odor resembling burnt oil, it's time for an oil change or refill.
• Overheating engine—a sudden temperature increase may indicate that the engine oil is no longer effective.
• Oil color change—if the oil appears dark brown or black, it is contaminated and must be replaced immediately.

Car Oil Change Schedule

To maintain your vehicle properly, it’s important to establish a regular maintenance schedule.

When setting up your schedule, consider factors such as:

• Driving distance and daily operating hours
• Weather conditions—oil should be changed more frequently in summer (every 3,000 – 5,000 km) than in winter (every 6,000 km)
• Driving conditions—rough terrain, extreme temperatures, and carrying heavy loads shorten the oil change interval.
• Car model and engine type—some engines consume more oil than others, requiring more frequent changes.

To ensure optimal engine performance, choose high-quality oil from Tollmart, where you'll find a wide selection of premium oils at competitive prices.

Changing Oil in New Cars

If you have a new car, you should know that many new vehicles come with storage oil, designed to protect the engine and its internal components during manufacturing and transport.

Since new cars may remain unused for up to six months, it's recommended to change the oil after six months or after the first 10,000 km. Storage oil generally has a longer lifespan than standard engine oils.
