3 Important Things To Know About Choosing Your Car’s Oil
There are many types of motor oil that are sold in the market today. All of them have very different purposes. It is up to you to determine which kind of oil will be the best for your car. Choosing the best motor oil for your car is really not that difficult. You only have to consider three important things related to your existing car.
What is the recommendation of the car manufacturer?
You don’t need to study the complex science of motor oil properties, production and utilization. All you need to know is to read the manual that comes with your car. What does the car manufacturer says? Follow the manufacturer’s recommendation since it designed and built the engine that makes your car run. The car manufacturer will specify the right type of oil that will make the engine of your car run smoothly. No matter what a motor oil supplier says, you should always take the word of the car manufacturer as your first priority.
How old is your car?
Is your car still under its warranty period, or is it already five years old or even older? If your car is still under warranty, you should strictly follow the instruction of the car manufacturer with regards to the motor oil that should be used. If you use another type of motor oil, based on the recommendation of a motor oil supplier, you may void the car manufacturer’s warranty. However, if your car is no longer under warranty, you can choose to use another brand of motor oil which you think may be more appropriate for your older car.
If your car has been serving you for five or more years, the original motor oil recommended by the manufacturer may no longer be sufficient. The worn parts of the car engine need heavier densities of motor oil. There will be small pits, microscopic cracks and other imperfections in the cylinders and other parts of the engine. They must be filled with the right density of motor oil to make the engine run smoothly as before. Therefore, you may need to need to consult a lubricant professional as to the right type of engine oil that is right for the present condition of your car’s engine.
What’s the average temperature in your place?
Your local environment plays a great part in the efficient performance of the motor oil. There are motor oils which work best in low temperature and vice versa. The same could be said with regards to altitude. This is where a viscosity chart could be of help in choosing the right motor oil for your car. Again, a lubricant engineer or professional will be your best help in this regard.
Other Important Considerations
In addition to the three key factors discussed above, you can also consider three important things that are used to define motor oil. These three things are viscosity ratings, classification codes, and additives. You will also be able to use this knowledge in choosing the best type of oil for your car.
Most often, a car manufacturer will recommend two or more motor oil with different viscosities for the car engines that it builds. The viscosity of the oil defines its ability to flow. For instance, the car manufacturer may recommend 5W-20 motor oil or 5W-30 engine oil. This is based on different conditions that include temperature, because car engines require various viscosities depending on the operating conditions.
Basically, oil additives are used to help the engine of your car run smoothly by keeping its temperature low, in maintaining its cleanliness, and in preventing corrosion on its metal parts. Oil refiners add and blend these additives to the base motor oil to infuse these qualities. On the average, about 25 percent of the cost of motor oil is taken up by additives. Motor oil additives are designed to improve and maintain oil performance. There are critical components of additives that help them perform these functions.
- Classification Codes
Classification codes for motor oil are important because viscosity is regarded as a very critical characteristic of motor oils. The Society of Automotive Engineers in collaboration with manufacturers of car engines has formulated this classification system that is based on measurements of oil viscosity. As such numbers or codes are assigned on specific motor oils to define their viscosity at given temperatures.
