Using 5W-30 in a 0W-20 engine can lead to reduced fuel efficiency and potential engine wear. The thicker oil won't flow as easily at lower temperatures, affecting lubrication during cold starts. This may result in less optimal engine performance. Always use the manufacturer-recommended oil viscosity to ensure your engine runs smoothly and efficiently. Check your owner’s manual for the right specification. If you’ve used the wrong oil, consider an oil change at your earliest convenience.
