Engine Oil Color Guide. Although oil color doesn’t necessarily concretely mean anything, it can still give us some clues about certain things. You could check the texture of the oil to give you a better idea of what’s going on. There are 2 general rules that can help guide you in engine oil coloration: Amber-colored oil is new, clean oil. Cream colored oil can indicate moisture. “Milky or frothy texture – often combined with cream color – indicates coolant (or water) contamination. Darker oil can mean several things – high heat, contaminants, additives that cause that darker color during normal use. “Dark brown or black motor oil can indicate contamination, but only if the oil is also THICK.” You can test which color your oil should be, by observing the changes in it over time. Take a note of the engine oil color as you check it every few days. You’ll eventually start to “read” your engine’s color. You’ll know what color it will be after a few thousand miles. You’ll know what color it should be when it’s time to change it and you’ll know if there’s possibly some sort of problem with it. However, we need you to remember that different oil brands or types give different color effects, so color information isn’t conclusive. Imagine this; even the weather can change the color of your engine oil too, even though it’s to a much lesser extent than other factors. Still, you should be observant and if you notice anything strange happening to your engine oil, you should call the professionals right away.
