Using the wrong engine oil can lead to reduced lubrication and shorter engine life. If the viscosity is not correct, your engine might not receive adequate lubrication, increasing friction and possibly causing engine overheating. Keep in mind, modern engines are designed for specific oil types. Always consult your vehicle’s owner’s manual and use the recommended grade of oil. In a pinch, using a slightly different oil once might not be catastrophic, but consistency in using the correct oil is key for long-term engine health.
