Choose The Right Motor Oil
Owning a vehicle can be a very expensive proposition and therefore it is important to understand some of the basic workings of your automobile. For example, do you know which type of oil is best for your car or truck? This is a very important question especially if you are a backyard mechanic who loves to tinker and do some of the more basic maintenance on your vehicle. This article will try to explain some of the things that you will need to consider before choosing a motor oil for your next oil change.
There are quite a few different types of motor oil available on the market today and each type is specifically designed for different purposes. To select the right type of motor oil for your car or truck it is important to first understand the significance of the oil classification codes, viscosity ratings, and oil additives. Understanding all of these three important categories will help you to choose the right motor oil.
An oil additive is something that will help the oil to keep your engine clean, cool, and corrosive free. Oil refiners often blend in different additives into the oil which can account for as much as 25% of the cost of the oil. When it comes to viscosity ratings, it is important to know that oil is identified and graded by its viscosity which simply means how the oil is able to flow.
There are two types of motor oil on the market today of which one is single viscosity oil and the other is multi-viscosity oil. The majority of vehicles that you see on the road are vehicles that are designed to run on multi-viscosity oil. Oil uses numbers to determine its thickness and the thinner the oil is means that it will flow more easily.
For example, a 10 W 40 oil has two numbers which means that it is a multi-viscosity oil. The 10 W is an index number that determines on how the oil flows during low temperatures that occur in the winter. The 40 is an index number that refers to how the oil will flow during high temperatures that occur in the summer. To determine which viscosity is best for your vehicle is simply a matter of looking into your owners manual for the oil viscosity chart.
The oil classification codes use a starburst symbol located on the oil container label. It signifies that the motor oil meets specific fuel economy and current engine protection standard requirements from the Approval and International Lubricant Standardization Committee (ILSAC). This Committee is a joint effort of the Japanese and US automobile manufacturers. Some of the symbols include the API stardust symbol, the API gasoline engine oil doughnut symbol, and the API diesel engine oil doughnut symbol.
Choosing the right motor oil for your car or truck requires a few answers to the following questions. For example, what is a type of oil are you currently using? If your vehicle is performing well then really there is no reason to switch motor oil brands. Also, what does your owners manual recommend for you to use? Vehicles that are still under a warranty should not use anything other than what is recommended. If the owner of a vehicle decides to use a different brand of motor oil it may invalidate the warranty for their new vehicle.
Another important consideration is whether you live in a hot or cold climate and is it flat or mountainous. Does the temperature where you live have sharp changes throughout the year. A multi-weight oil is the best choice for locations that have a range of temperatures. When you see the letter "W" it means that the oil works better in a cold climate.
Finally, you need to determine how worn your engine is. Engines that have logged many miles over a long period of time on a single 30 or 40 weight oil will have problems if they switch to multi-weight oil. The reason for this is that the oil is thinner and it will not be thick enough to lubricate worn engine parts that over time have become smaller and have worn down.
