Picking the right motor oil for your vehicle

Car owners are confronted with a variety of motor oil choices. For those who want to make the easiest decision, pick a brand-name option that matches the manufacturer’s specifications and certification requirements. You should also make sure that the oil is changed on schedule. But just what do those specifications mean?Each type of oil is rated according to a system developed by the Society of Automotive Engineers (SAE). This system describes the viscosity of the oil. A typical rating looks something like 10W-30. The first number describes the viscosity in cold temperatures (“W” is for winter), with lower numbers meaning more flow. The second number, of course, refers to the viscosity (also known as heaviness) in warm temperatures.Newer cars will have a range of acceptable oils, so you can make a decision based on your typical driving habits. Regular drivers in moderate temperatures might choose a 5W-30 option for a new car and a 10W-30 oil for older vehicles. For cars in hot weather environments, you can afford to go higher on the second numberperhaps a nice 10W-40. In colder temperatures, you should go the other way, choosing a lower W number.Besides viscosity, oil is also divided by composition. The two basic types are mineral and synthetic. Mineral oils come from refined crude oil, while synthetic oil is manmade and is unique in having molecules of the same size and shape. This causes less friction, and means that synthetic oil generally performs better than mineral. For those who don’t regularly subject their vehicles to extreme conditions, though, synthetic oil may be overkill, given its significantly higher price compared to mineral oil. Approximately 15-25 of any type of oil’s make-up comes from additives, which are often used to reduce residue formation, block air absorption, protect against wear, and defoam.So how can you decide what type of oil is best for your vehicle? The simple answer is to follow the standards of the carmaker, but you can also tailor your oil choice to your particular driving needs. If you ever have any questions about whether a certain type of oil will work for you, contact your nearest automotive professionals, and make sure you get all the information before potentially damaging your engine.
