Find your oil dipstick, pull it out and check the level of oil and its color.
If the oil is a dark-brown or black color, like Coca-Cola, then your oil needs to be changed.
However, if it appears to be lighter, like the color of a cup of tea, then you still have some time before it needs to be changed.
How can you tell if oil is bad?
6 Signs Your Car’s Oil Needs Changing
- Check Engine or Oil Change Light. The most obvious alert that there’s an issue with your oil will come from the car itself.
- Engine Noise and Knocking.
- Dark, Dirty Oil.
- Oil Smell Inside the Car.
- Exhaust Smoke.
- Excessive Mileage.
- Change Oil Promptly.
What is oil supposed to look like?
Motor oil is generally light-coloured and transparent, but will darken over time. If the oil on the dipstick appears black, it’s a sign that you’re due for an oil (and oil filter) change. Beware light brown and milky oil: this may be a sign that your coolant is leaking into the crank case.
What color is synthetic motor oil?
If you aren’t using a synthetic oil blend, and your oil is dark and sludgy, you are past due for an oil change. The oil is saturated with engine muck.
