Let's Learn about Motor Oil Viscosity Ratings

You know that your car needs appropriate oil and periodic oil changes, but motor oil viscosity ratings can be confusing. We can clarify this matter right now at the Brian Harris BMW service center!

First, let's discuss viscosity. This property classifies a liquid's resistance to flow. Thin liquids like tea barely resist flow, so they feature low viscosity. On the other hand, thick liquids tend to flow sluggishly, so they feature high viscosity. Common ratings found on motor oil containers include 10W-30 and 5W-20. The number before the W is an oil's viscosity in a cold engine. To the dash's right, we find the oil's viscosity in a hot engine. Always use the oil viscosity rating prescribed in your owner's manual.

If you have additional questions about the right oil for your car, contact our BMW service facility in Baton Rouge, LA. We will happily answer your questions, and we can conveniently schedule your next oil change.
