Understanding Engine Oil Colour: Key Things You Should Know
Engine oil is vital for vehicle performance. A well-maintained engine ensures smooth operation, and healthy engine oil is essential for this. Engine oils protect against heat, friction, and wear while removing waste and metal particles. Thus, vehicle owners must ensure their engine oil remains in good condition.
The Federation of Automobile Dealers Associations (FADA) has shared insights on engine oil colour and condition. This information helps in understanding when to change the oil. Let's explore these details further.

Amber or Gold
New engine oil is amber or golden, indicating cleanliness and optimal condition. This colour signifies fresh oil, which is ideal for engine health. Ensuring the oil remains this colour after each change is beneficial.
Light Brown
When engine oil turns light brown, it signals prolonged use and the need for a change. Ignoring this can shorten the engine's lifespan. Therefore, if your oil appears light brown, replace it promptly to maintain engine efficiency.
Dark Brown or Black
Dark brown or black engine oil indicates significant waste contamination. This condition demands immediate replacement to prevent rapid engine failure. Delaying action could lead to severe engine issues.
Milky or Creamy
A milky or creamy appearance in engine oil suggests coolant leakage, posing a serious threat to the engine. This condition requires careful monitoring and immediate attention to avoid further damage.
Red
If engine oil appears red, it may indicate a leak or contamination entry point. Immediate investigation is crucial to identify and resolve the issue, preventing potential harm to the engine.
Green
Green-coloured engine oil confirms contamination presence. Immediate replacement is necessary, along with identifying the contamination source to prevent recurrence. Addressing this promptly ensures continued engine health.
