Have you looked at your engine oil viscosity rating before purchasing motor oil? You’ll want to check the vehicle’s owner manual to see what your manufacturer specified is best for your engine. The wrong viscosity could lead to diminished fuel economy and degraded engine performance over time.
Your motor oil viscosity is the measurement of how easily your oil flows at different temperatures. In colder weather, lower viscosity is best, such as a 5W-30. The 5 before the “W” is a measurement of how viscous the oil is at freezing temperatures. That’s why this number should always be low if you’re looking for oil to perform better in winter.
However, the number after the W stands for how viscous the oil is in extremely hot temperatures. You want this number to be higher if constantly driving in hotter climates, such as a 15W-40. If you have questions about your motor oil, you can always talk to the experts at Cole-Krum Chevrolet, LLC located in Schoolcraft, MI.
