Using the wrong oil viscosity can lead to inadequate lubrication, increased engine wear, and potential overheating. It's essential to use the recommended oil viscosity for your specific model year.
What is an oil life monitor and how does it work?
An oil life monitor is a system that tracks engine conditions and driving habits to estimate when an oil change is needed. It takes into account factors like temperature and engine load to provide a more accurate maintenance schedule.
Can I mix synthetic and conventional oil?
