Do you know how motor oil grades and viscosity relate? Typical motor oil will have a grade of 5W-20 or 5W-30. In other cases, you might see 15W-20. This grade relates to the amount of viscosity in your motor oil, which is important if you drive in extreme temperatures or require a certain motor oil grade according to your vehicle’s owner manual. You’ll want to check before picking out any motor oil to change on your own.
The “W” in the grade represents “winter” or how well your oil will perform in lower temperatures. The number before the “W” tells you how viscous your oil will be. A lower number like a 5W-30 is a low viscous oil that’s best for cold weather, as it flows better than a 15W- would in cold temperatures.
The number following the “W” stands for how thick the oil is. If you live in a very hot area, you should expect this to be a higher number when you live in a hotter climate. Need help with your motor oil? Stop by Firelands Chevrolet Buick to get the best service and oil change rates in Norwalk, OH.
