How to Check Your Car's Oil (Without Looking Like an Idiot)
Modern cars are essentially rolling computers. If a tire is low, a sensor yells at you. If you veer out of your lane, the steering wheel vibrates. But despite all this technology, one of the most catastrophic failures a car can experience—running out of engine oil—still relies primarily on a metal stick dunked into a pan of grease. If your engine runs out of oil, the metal parts will grind together, generate massive heat, and physically weld themselves together, effectively destroying a $5,000 engine in minutes. You cannot rely solely on the dashboard light. Taking a few seconds to check the dipstick yourself is an essential piece of preventative maintenance.
Park on flat ground and wait
If you check your oil while parked on a steep driveway, the oil in the engine pan will slosh to one side, giving you a completely inaccurate reading. Always park on a level surface. Also, do not check the oil immediately after driving a long distance. When the engine is running, the oil is pumped up into the top of the motor. You need to turn the car off and wait about five to ten minutes for all that oil to drain back down into the pan at the bottom. This ensures you are measuring the total volume.
Find the brightly colored dipstick
Pop the hood of your car. (If you don't know how, there is usually a lever under the steering wheel, and a secondary safety latch under the front lip of the hood itself). Look at the engine. You are searching for a small ring or handle that is usually painted bright yellow or orange. It often has the word 'OIL' stamped on it, or a picture of an old-fashioned oil can. This is the dipstick. Grab it and pull it straight up. It will be a long, flexible piece of metal.
Wipe it completely clean and put it back
This is the step everyone forgets. When you pull the dipstick out the first time, it will be covered in oil from the engine splashing around. You cannot read it yet. Take a clean paper towel or an old rag and wipe the metal stick completely clean from top to bottom. Once it is shiny and clean, slide it all the way back down into the tube it came from. Make sure it clicks or pushes all the way down to the base.
Pull it out again and read the level
Now, pull the dipstick out a second time. Hold it horizontally so the oil doesn't run up or down the stick and ruin the reading. Look at the very bottom tip. You will see two marks. They might be two small holes, the letters 'L' and 'F' (Low and Full), or a crosshatched pattern. The film of oil should end right between those two marks. If it is right in the middle or near the top mark, your oil level is perfect.
- Above the top mark: Overfilled (Bad, can cause pressure issues)
- Between the marks: Perfect (You are good to go)
- Below the bottom mark: Dangerously low (Add oil immediately)
Check the color and consistency
While you are looking at the level, look at the oil itself. Fresh engine oil is a transparent, amber color, like honey. As it does its job cleaning the engine, it gets darker. If it is dark brown or black, that's completely normal for older oil, but it means you are due for an oil change soon. If the oil looks thick, sludgy, or milky like a coffee frappuccino, put the dipstick back and call a mechanic immediately—a milky texture means engine coolant is leaking into the oil system.
