The heat of the engine causes the oil to oxidize, and the detergents start working to trap the microscopic contaminants that cause sludge. However, the sheer volume of microscopic particles—such as unburned fuel, soot, and metal shavings—that enter the oil will inevitably alter its appearance.
Understanding and Fixing Engine Oil Color Foamy White Issue
The exact viscosity—such as 5W-30 or 10W-40—does not dictate the color as much as the additive package does. Black and gritty: While generally normal for aged oil, extremely black oil that feels excessively gritty might indicate a severe accumulation of soot, potentially pointing to a rich fuel mixture or failing turbocharger.
Fresh oil is liquid and pours easily, while used oil will be thicker. Conversely, if the oil feels稀薄 (thin) and watery, it may have been diluted with fuel or suffered a loss of viscosity due to overheating.

New Oil and Ideal State When you first pour fresh oil into an engine, it is usually a light amber or honey-like color. This is a completely natural process and not a cause for alarm.
