When Change Oil Car: The Difference Between An Old And A New CarMay 4, 2021
When change oil car is a question any car owner will face. While this matter is simple for experienced drivers, beginners may find it a little confusing and don’t know what to do. With that in mind, Onroadtips have compiled a comprehensive guide that will help you answer this question and properly take care of your vehicle.
If you are wondering why changing oil is so important, the reason is that it lubricates engine parts as they are constantly in friction that cause the engine to tear and wear out faster.
Besides, oil plays a crucial role in cooling the engine by providing lubrication and cleaning the engine by carrying the microscopic buildup to the oil filter. You can conduct an Italian tune-up to remove the buildup but you still have to change the oil at some point eventually.
When to change oil for car?
The exact time to change your car oil is determined by a number of factors such as the type of oil you use, the driving conditions, and the age of the vehicle. From these, you can figure out the interval between two consecutive oil changes, hence when change oil in car.
However, your car may have a specific warning light for oil change. When it illuminates, it means you should have the oil changed as soon as possible.
How often should you change car oil?
More recent models tend to come with an oil-life monitoring system that tells you when to change the oil through an alert on the dashboard. Early systems gave these warnings based on mileage and time but advanced systems now analyze the car’s operating conditions to determine when the oil starts to degrade.
In fact, such high-tech systems have eliminated the need for severe service recommendations in the maintenance manuals for many cars because they automatically reduce the time to the next oil change if it detects heavy-duty operation. As soon as the oil is changed, the oil-life monitoring system should be reset, this can be done by a service technician or yourself.
However, as the oil requires less frequent changes, you need to check the oil level every month and fill it if necessary. The amount of oil you need to top up varies between cars. By filling the oil tank on a regular basis, you will be able to avoid damages to the engine, saving a lot of money.
For older cars, how often change oil car often relies on the mileage and there are two schedules for normal operation and severe service. The severe service includes:
- Mostly short trips (under 8 km)
- Extreme climate (cold, hot, or dusty)
- Constant stop-and-go operation
- Heavy loads carrying or trailer towing
If your car undergoes severe service, you need to change oil more frequently. Otherwise, you should consider carefully before spending money on an unnecessary oil change.
How to choose the right oil for your car?
The viscosity of a fluid is how resistant it is to flow, rated based on its thickness at 0 degrees F and 212 degrees F. Motor oil tends to get thinner at higher temperatures and thicker at lower temperatures. At the same time, thicker oil provides more lubrication and is better for the engine. So, in hot weather, the higher the viscosity rating, the better.
On the other hand, when it’s cold, oil can become too thick and more resistant to flow than it should. This means it won’t flow properly, making it harder for the engine to start up. Therefore, in this case, a low resistance to flow is better.
Viscosity includes both the rating for hot conditions (the first number) and cold conditions (the second number). When shopping for car oil, you should check out both these indicators.
Types of oil
All brands make conventional oil, which is the standard type for a new car with different viscosities. For light-duty cars, the recommended ratings by carmakers include 5W-20, 5W-30, or 10W-30.
This type of oil is meant to serve heavy-duty cars and high-tech engines. It features a lot of additives and have a better flow at low temperatures while remaining thick at high temperatures. However, these oils usually cost a lot and not all cars requires synthetic oils.
Synthetic blend oil
This is a mix of synthetic oil and organic oil to protect the engine from high temperatures and heavier loads. Synthetic blend oil evaporates much less, reducing oil loss and raising fuel efficiency. This type is commonly used for pickup trucks or SUVs that need extra protection. Also, it’s much more affordable than synthetic oil.
Due to the advancements in vehicles and drivers’ demand, companies have come up with a new type of oil that helps cars runs for higher mileage before it needs an oil change.
Specifically, it consists of conditioner flowing into the engine seals’ pores, which restores their shape and increase flexibility. This is especially helpful if your car belongs to the older generations in the car world.
Additives are included in engine oil to boost and maintain performance. The following are some additives you should seek when shopping for car oil.
- Viscosity-index improver: with this additive, oil less likely gets thin at higher temperatures.
- Detergent: it removes deposits from oil, keeps the surface of the oil clean.
- Dispersant: it disperses particles to prevent them from coming together and forming sludge, acids, or varnish.
- Antiwear agent: it’s meant to protect the metal surfaces when the lubricating film generated by oil breaks down.
While washing the car engine does help clean it and smoothen the operation, but oil changes are inevitable. All in all, this post focused on answering two big questions: When change oil car? And how to choose the best car oil? Changing oil is a simple but important task to keep your car operate smoothly, we hope this post will help you do that properly.
