Think colder temperatures only affect your battery? Think again! 🥶
As temperatures drop, motor oil naturally thickens, making it harder to flow freely and circulate through your engine, especially during startup. Using the wrong oil viscosity can contribute to increased engine wear and reduced performance over time.
The good news? A little preventive maintenance goes a long way! Check your owner's manual for the manufacturer-recommended oil viscosity to help keep your vehicle running smoothly through the colder months.
