To keep your car performing to the best of its ability, you should have scheduled oil changes. However, it is also important that your vehicle's motor oil has the correct viscosity rating. To learn more about motor oil viscosity ratings, read below.

Have you noticed numbers and a letter on bottles of motor oil? This indicates its motor oil viscosity rating. For example, a 10W-30 motor oil means that its viscosity in cold weather is the number before the W, and the number that follows the W is its viscosity in hot weather. Because lower cold weather velocity numbers have more resistance to flow, it is best to use a motor oil with a low viscosity during the winter.

Is your vehicle in need of an oil change? If so, stop by our service center at Quality Mitsubishi in St. Johnsbury, VT.
