What Colour Should My Engine Oil Be?
Engine oil comes in a variety of colours, each corresponding to a specific level of viscosity and performance. The most common colours are:
| Colour | Viscosity | Performance |
|---|---|---|
| Red | Low | Engine start-up and low-temperature performance |
| Orange | Moderate | General driving conditions |
| Yellow | High | High-performance driving and extreme temperatures |
| Green | Very High | Severe driving conditions and high-performance applications |
But why do engine oils come in different colours? The answer lies in the viscosity of the oil. Viscosity refers to the oil’s thickness and flowability. Thicker oils are better suited for cold temperatures and high-performance driving, while thinner oils are better for hot temperatures and general driving conditions.
