What does oil and coolant look like when mixed, you ask? Gravy! Yes, if there is motor oil in your antifreeze/coolant, you’ll be able to tell by the color—it’ll be a smoky/milky sort of color and be very viscous. Some mechanics have described it as looking like gravy.
That’s one of the reasons why it’s crucial to check on your car’s various fluids regularly.
If that sounds like what you’re dealing with, you’ll want to drain your coolant reservoir, flush it thoroughly, and then refill it with entirely fresh coolant.
Always use care and caution when changing your oil and wipe up any stray drops that may have splattered around. For more great car-care tips and to save tons of money on your car insurance—download the Jerry app!
