How Long Does Synthetic Oil Last?

As we all know, it is essential to oil the engine of a vehicle in order to make sure that the engine works smoothly and efficiently.

Over the past several years, people all over the world have been using either synthetic oil or mineral oil in their car engines. However, we typically use synthetic oil over mineral oil in our cars.

When you use synthetic oil in the engine of your car, you need to get the oil changed after a certain period of time. But when it comes to getting the oil change, there are several factors that play major roles in how often you have to get the oil replaced.

In this guide, we will discuss how long does synthetic oil last and several other factors associated with it.

How Long Does Synthetic Oil Last In A Car?

Synthetic oil in the engine of the car is quite beneficial for the health of both the car and the engine. Almost all of the recent car models depend on synthetic oil, and in all honesty, the choice is fair.

Synthetic oil comes with several properties that benefit the car, such as improving friction on the road, reducing overheating of the engine, and so on. On top of these, synthetic oil also lasts a bit longer compared to other traditional engine oils or mineral oils.

If we talk about the longevity of synthetic engine oil in general, experts usually recommend an oil change once in every 6 months or 1 year. If we talk about the miles traveled by the car before the engine requires a synthetic oil change, experts typically suggest an oil change between 6,000 miles to 10,000 miles.

However, these general suggestions are only estimations, and the actual longevity varies depending on several factors. In today’s world, the rule of thumb about oil change stating that it has to be changed within a certain period of time or after the car has traveled a certain amount of distance does not really work. The longevity of the synthetic oil can change drastically in case any of the severe factors change significantly.

How Do Different Factors Affect The Longevity Of Synthetic Oil?

Viscosity

Synthetic oil is usually known to be more thermally stable compared to other traditional engine oils. The viscosity of the engine oil affects all types of engine oil, but the synthetic oil lasts for a longer period of time as they do not break down easily under high temperature. On top of that, synthetic oil comes with a few additional ingredients that make viscosity loss slow and increase its lifespan.

Engine Type

A lot of car owners think that premium quality or expensive engine oil will last longer than the less expensive ones. While the quality plays a role in the longevity of the synthetic oil, it is not the deciding factor. The type of engine and whether you use gas-fed or diesel-fed engines also play a major role in the synthetic oil replacement. When it comes to the comparison between gas and diesel, you will notice that diesel is raw and creates more pollutants compared to gas. This causes the oil change interval to decrease even if you use top quality synthetic engine oil.

If your car uses turbocharged engines instead of regular engines, then the oil change interval will also decrease. This is because regular engines stop spinning as soon as you turn it off, but turbocharged engines spin for a long time after you turn it off. This causes a high amount of heat generation, which in turn creates contaminants that break down the synthetic oil.

Mileage

Another factor that affects how long synthetic oil is the mileage of the car engines. If we draw a comparison between new engines and high mileage engines, then we will notice that engines with a high mileage will require a more frequent oil change.

This is mainly because engines that have traveled a lot of miles will have more unburnt or unused fuel present in the engine. The old pollutants mixing with the new synthetic oil will cause the oil to break down faster and will downgrade the quality, so the car engine will require oil change more frequently.

Pattern Of Driving

The style of driving a car typically depends on two factors: the lifestyle of the driver and the place or location where they live in. The oil change interval that engine oil manufacturers typically advise is completely based on standard or ideal conditions, meaning that the results can widely vary depending on real-life conditions.

Cars in small towns or the outskirts usually require more frequent and severe oil changes and car servicing compared to cars in well-crowded cities and highway accessible areas.

Driving Conditions

If you regularly drive your car where the surrounding is dusty, then a large amount of dust and dirt can enter the engine even if you use premium air filters in your car. The pollutants present in the air can enter the engine of the car and pollute the synthetic oil, causing it to lose its working properties faster.

On the other hand, driving a car in areas where the weather is too hot or moist can cause oxidation of the engine oil and decrease its longevity.

Car Monitors

In today’s date, the majority of cars come with monitoring devices installed. These devices are typically used in order to record information such as how many miles the car traveled, driving hours, driving conditions, and so on. These pieces of information allow the driver to know the suitable time for an oil change.

However, no matter when the monitoring device suggests the oil change, you must make sure to change the engine oil of your car at least once or twice a year.

Car Maintenance

It is true that well-maintained cars provide service for a longer period of time compared to cars that do not receive proper servicing or maintenance. A lot of car owners allow the engine of the car to sit idle for a long time and do not bother starting the engine every once in a while, as they think that it will only cause wastage of diesel or gas.

However, keeping the engine clean of pollutants and servicing the car regularly will not only increase the time period of your oil change, but will also let your car run smoothly for several years.

Frequently Asked Questions – FAQ

1. Is It Necessary To Get An Oil Change?

Yes, if you want your car to run smoothly and efficiently on the road and want to keep the engine healthy, then it is absolutely necessary to get an oil change once or twice a year. When it comes to car engines, you just cannot compromise or ignore the importance of engine oil.

2. Is Synthetic Oil Better Than Traditional Engine Oil?

Both synthetic oil and traditional engine oil, also known as mineral oil, are popular choices when it comes to choosing engine oil. However, if we were asked to draw a comparison between the two, then synthetic oil is better than mineral oil in quite a few ways. One of these reasons is that synthetic oil has the ability to offer a full protection to the car engine, and this is something that the mineral oil cannot do.

3. Does Oil Change Affect The Fuel Economy Of A Car?

Fuel economy is a factor that you must keep in consideration when you use a car. Fuel economy is typically used to represent the number of miles that a car travels on a certain volume of fuel. Oil change has a major impact on the fuel economy of a car, and not changing the engine oil properly causes damage to the fuel economy. A damaged fuel economy means that the car will use more fuel than usual, and this means that you have to make frequent trips to the gas station.

Conclusion

The typical timeframe or mileage that is used to measure the longevity of synthetic oil is an approximation and varies due to several factors, as we discussed above. So, depending on the usual definition of how long does synthetic oil is not really a smart move. Instead, you must pay attention to all the signs that indicate whether you need an oil change or not.
