How to Measure the Color of Motor Oil

Motor oil is one of the most critical components for a machine's maintenance and upkeep. Many auto manufacturers suggest that owners check their engine oil at least once a month to ensure their combustion system is operating correctly. If your engine is burning or leaking oil, it's vital to address the problem as quickly as possible before it becomes a severe issue.

While a quick and concise oil check takes only a few minutes, the time investment is wise considering the potential damage a problem can cause when ignored.

What Color Should Engine Oil Be?

Those who change their motor oil and frequently monitor its levels know its color changes over time. As the oil changes, each color has a meaning. The oil used for most engines begins as golden amber and changes to a dark brown and eventually black.

Oil darkens when exposed to heat and oxygen, ultimately losing its ability to lubricate your motor's components and absorb heat from the combustion process.

Besides darkening naturally, motor oil changes color when contaminants are present, suggesting something significant could be wrong with your machine's engine. Many automobile or equipment owners prefer to monitor how their motor oil changes color over time, showing how quickly the product breaks down.

How to Measure the Color of Motor Oil

Most automobiles and other machine types have a dipstick that indicates oil levels. Oil on a dipstick is an effective way for consumers to estimate its viscosity and color. While a smooth, amber-colored oil is a good indicator of newer oil, thick, sludgy and black oil usually means it has reached the end of its life. Nevertheless, you must remember that outside contaminants can affect an oil's color, even if the fluid is relatively new.

Most oil and lubricant manufacturers employ advanced color measurement techniques to ensure their fluids meet the highest color consistency levels. These tools are critical because many repair shops and consumers depend on lubricant color to differentiate fluids, like distinguishing between motor oil and transmission fluid.
