What should your idle speed be?

Idle speed varies depending on the type of vehicle and engine specifications. Generally, for most gasoline engines, it typically ranges from 600 to 1,000 RPM, while diesel engines may idle around 600 to 800 RPM. It's best to consult your vehicle's owner manual for the manufacturer's recommended idle speed for optimal performance. Regularly checking and adjusting idle speed can help ensure smooth operation and fuel efficiency.
