• High mileage: As the engine accumulates more miles, the oil can turn reddish due to normal wear and tear.
• Wrong oil type: Using the wrong type of oil can cause it to turn red. For example, using transmission fluid or hydraulic oil in the engine could result in red oil.

Oxidation occurs when the oil reacts with oxygen and heat, causing it to break down and turn red or brown in color. Additionally, if you are using a high-mileage oil or oil with certain additives, it may turn red over time as a normal part of its performance.

However, if you notice other symptoms, such as a burnt smell or engine performance issues, it is important to have your vehicle inspected by a professional to rule out any potential problems. Regularly changing your engine oil, as recommended by the manufacturer, can help prevent oxidation and maintain the health of your engine.
