Choosing the correct motor oil for your car depends on knowing oil viscosity. Usually expressed on the Society of Automotive Engineers (SAE) scale, viscosity is the resistance of an oil to flow. We shall define oil viscosity, discuss the meaning of oil grades, and offer advice on selecting the correct oil for your car in this post.
Knowing Oil Viscosity
Oil viscosity affects motor oil performance. Thinner oils, such as 0W-20, flow faster than thicker oils like 20W-50. Whereas the second number in an oil’s grade, such as 0W or 20W, denotes the oil’s viscosity at operating temperatures, the first number indicates the oil’s viscosity at low temperatures. To ensure your engine receives the right viscosity for optimal performance, scheduling an oil change in Topeka, KS can help maintain efficiency and longevity.
Knowing Oil Grades
Standardized testing run by the SAE help to establish oil grades. The SAE rates motor oil viscosity using a two-part system, say 10W-40.The oil’s winter-grade viscosity is indicated by the first number followed by a “W; its summer-grade viscosity is indicated by the second number. Note that viscosity varies among oils; none of them are exactly the same. For low temperatures, for instance, a 10W-40 oil is thicker than a 5W-30 oil; but, at running temperatures it is thinner. For your particular vehicle and operating circumstances, then, it is imperative to choose the appropriate oil viscosity.
Choosing the Right Oil Viscosity
Checking your car’s manual is the easiest way to choose oil viscosity. Based on the age, operating environment, and engine type of the vehicle, most manufacturers of automobiles offer prescribed ranges of oil viscosity. Also important are temperature, driving style, and vehicle changes. In cold climates, a thinner oil like 5W-30 may improve cold-start performance. If you frequently pull heavy objects or drive in hot weather, you may want to use a heavier oil like 10W-40 for engine protection.
Synthetic vs. Conventional Oil Viscosity
Synthetic oils often offer a larger range of possible viscosities than conventional oils. Better performance and protection in harsh temperatures and driving situations are what synthetic oils are meant to deliver. For cold-starting, for instance, a 0W-20 synthetic oil can outperform a 5W-30 conventional oil.
Advice for Preserving Oil Viscosity
Maintaining the proper oil viscosity guarantees best engine efficiency and protection. The following are some guidelines:
- Check your oil often; top off as needed.
- Use the oil viscosity advised by your manufacturer of vehicle.
- Change your oil and filter following manufacturer advised timetable.
Conclusion
For improved performance and protection in demanding temperatures and driving situations, think about using synthetic oils. To choose the correct motor oil for your car, then, knowledge of oil viscosity and oil grades is essential. By following the guidelines mentioned in this article, you can assure optimal engine performance and protection.
