Engine oil lubricates the engine and prevents its overheating. Overtime, oil breaks down which loses its ability to prevent friction between the engines's moving components.  Hence, you need to change oil at regular intervals. Here we have discussed how often you should change your oil. 

How Often to Change Your Oil?

The traditional oil change interval that has been followed for several years is 3,000 miles.  According to auto experts, the oil change every 3,000 miles does not apply to new cars. Modern cars have refined engine technology and the gap between moving parts is greatly reduced.  This makes the engine use less oil and also prevents build-up. Also, modern lubricants have additives that extend the life of the oil. 

If you drive a new car, you can change the oil every 5,000 miles. Check the car's manual to know the right oil change interval. Make sure you go by the car manufacturer recommendations regarding engine oil type, viscosity, and other specifications. The car manufacturer can be considered as the final word regarding how often you should change your oil. 

How Often to Change Synthetic Oil?

Synthetic oil is far better than traditional motor as it has fewer impurities. According to auto experts, the oil change interval for synthetic oil can be anything between 5,000 to 10,000 miles. Again, it is the car manufacturer's recommendations that matter most. If the car manufacturer has recommended "every 10,000 miles" as the oil change interval for synthetic oil, go by the recommendation. 

Though we have mentioned generally followed oil change intervals, there are certain factors that affect the oil change interval like driving habits and the environment.  Here is the list of instances when your car needs frequent oil changes. 

Instances for Frequent Oil Changes 

Some cars may need oil changes every 3,000 miles under severe driving conditions. Here is the list. 


Driving on Dusty, Sandy, or Gravel Roads

If you are driving on gravel, sandy, or dusty road, there are more chances fine dust particles enter the engine and get mixed with oil and make it thick and dirty. Less flowing oil does not lubricate the engine well and the solid dust particles can further damage engine components. Hence, you need to change the oil every 3,000 miles. 

Frequent Short Trips of 5 Miles or Less

If your car goes only for short trips, the engine condensation can cause an early breakdown of oil. The moisture in the air turns into water droplets and mixes with oil. On long trips, the engine heats up and causes the water in the oil to evaporate, extending the life of the oil. 

If the car's engine never heats up enough to vaporize water in the oil, it causes the water molecules to react with additives to become insoluble particles that can damage the engine. Hence, you should change the oil every 3,000 miles. Also, if you live in a cold region and drive less than 10 miles most of the time, you also need to change engine oil every 3,000 miles. 

When you change oil at right intervals, your engine stays in good condition, performs well and you will experience a reduction in engine repair costs.
