Differences Between Red and Yellow Engine Oil Warning Lights

Model: (Various brands) Various
Part: Service warning light

Many cars have two oil warning lights: one red and one yellow. The red light indicates a danger, as it shows that there is insufficient pressure in the oil circulating in the engine. Once this light comes on, there is a maximum distance you can drive, not much, after which the vehicle enters 'recovery' mode, resulting in a loss of power to reduce the risks of poor lubrication. When the yellow light comes on, it means that the engine oil level is at a minimum. However, it is advisable to always check with the dipstick before topping up, as a sensor failure is always possible, and adding oil unnecessarily can cause serious damage to the engine.
