Why Engine Oil Matters
It does not matter if you are using conventional motor oil or full synthetic oil. What matters is that you should use the right motor oil because it will extend the life of your vehicle and keep it running efficiently for many years. There are many types of engine oil out there, so you should choose the one that is just right for your vehicle.
Understanding What Motor Oil Does
When your car is in motion, motor oil moves through the engine system and lubricates the engine and its components. Engine oil also picks up contaminants that may harm your engine. As the motor oil does its work, it gets dirty and less viscous with time. When the oil gets dark, it is time to change your motor oil.
However, you do not have to wait until the motor oil loses viscosity entirely before an oil change. Some manufacturers recommend that you change motor oil after every 3,000-5,000 miles. Your engine oil should not be too think or too viscous. It just needs to have right consistency.
Engine oil must be able to function effectively in both cold and hot weather. It should flow during the winter months and maintain its thickness even the heat of summer. This way, your car is protected no matter how hot or cold the weather gets.
The Society of Automotive Engineers (SAE) has an excellent grading system that determines the viscosity of engine oil. This system is arranged in a set of numbers: 0, 5, 10, 15, 20, 25, 30, 40, 50 and 60. The numbers how thick the oil is and the temperature best suited to it.
In the past, car owners used a different grade of oil in winter and a different one in summer. This was because the same grade of oil did not work in different weather conditions. These days, that problem has been solved. Now, you can use the same grade of oil throughout the year.
When you use multi-grade oils, you will notice that two numbers are listed. One number indicates the viscosity for warm temperatures while another number indicates the viscosity for summer.
How Viscosity is Measured
The device used for measuring viscosity is a viscometer. This device measures how fast or how slow the oil flows and the results are noted. The average temperature of a running engine is 212 degrees Fahrenheit and this is the temperature at which viscosity tests are carried out.
Multi-grade oil is manufactured to perform at both high and low temperatures. This is the right oil for car owners because you are protected no matter the weather condition.
When engine oil is thick, it will flow slower through the viscometer and it will be given a higher number. On the hand, when it flows faster, it will have a lower number. You should know this so that you buy the oil that is just right for your vehicle.
Multi-grade oils usually have additives. Additives protect your engine from wear and tear but they can get depleted and this might expose your car to danger. This is why you must change your engine oil at the right time.
Generally, synthetic oils do not contain additives because they function effectively in all temperatures. The thing is that these oils are not meant for all vehicles. Check your owner’s manual for the recommended oil and only use the one recommended by the manufacturer of your vehicle.
If the oil is too thick or too thin, it will not protect your vehicle. To ensure that you have the perfect engine oil for your car, contact South West Automotive to give you the right recommendation.
