How to Check if Engine Oil is Normal?

[JasperAnn]

Methods to determine if the engine oil is normal: 1. Use the oil dipstick to check. When removing the dipstick and the oil is about to drip, observe if there are any debris or impurities in the oil. If present, it indicates the oil is abnormal. 2. Dip your finger into the oil and lightly rub it between two fingers to observe if the viscosity is normal. 3. Take a clean white piece of paper and drip a few drops of oil from the dipstick onto it. This will allow you to clearly see the color and cleanliness of the oil. 4. Engine oil can also deteriorate. Remove the dipstick and smell it. If there is a foul odor, the oil is abnormal.

I usually wait for the car to be turned off for ten minutes before checking the oil on a flat surface to ensure accuracy. Open the hood, pull out the yellow-ringed dipstick, wipe off the old oil with a clean cloth, reinsert it all the way, and then pull it out again to observe. The oil level should be in the middle to upper part of the scale between the upper and lower marks. If it's below the middle line, you should add some oil. Pay attention to the oil color; it should be honey-colored with a transparent appearance. If it turns black like asphalt or becomes milky white, it's a bad sign. I always keep the same type of oil in my car. If I find the level is low, I unscrew the filler cap and slowly add oil using a funnel. Remember to check at least every three months, especially before long trips to ensure the oil level is adequate.

I prefer checking the dipstick when the engine is cold and absolutely hate doing it on a slope. Never skip the steps of pulling it out, wiping it clean, and reinserting, otherwise the residual oil on the dipstick can lead to misjudgment. While checking the oil level, pay attention to its texture as well—healthy oil should have a viscous oil film. If it feels thin like water or contains metal particles, it's a danger sign. Last week, my car's oil was dark and stringy, so I promptly changed it. A reminder to everyone: especially check before winter, as low temperatures can reduce the flow of old oil, potentially causing hard starts or even cylinder scuffing.

Checking the oil right after parking is definitely inaccurate; waiting fifteen minutes before proceeding is the safest approach. The dipstick has two notch markings at the end—as long as the oil stain covers the meshed area between the high and low marks, it's safe. Besides the level, I carefully sniff for odor—normally there's just a faint oil smell, but a burnt scent might indicate lubrication issues. While checking the oil, I also pinch the hoses to check for cracks, as aging rubber tubes leaking oil is a common problem. I record the mileage during every maintenance to keep track of the oil degradation cycle.

I set a reminder on my phone every time I change the oil, and I make sure to check it at every 5,000 kilometers. When checking the oil level, the car must be perfectly level—any tilt can lead to misjudgment. If you find the oil level is low, don’t rush to add new oil; first, check the undercarriage for any oil stains, as it could indicate a leak from the oil pan or gasket. Be alert if the oil color changes suddenly: black suggests excessive carbon buildup, milky indicates water contamination, and a bluish smoke smell points to oil burning. Recently, I learned the blotter test method—drip a drop of used oil onto filter paper, and the clearer the diffusion ring, the longer the remaining oil life.

Check engine oil in conjunction with dashboard warning lights. First verify the oil level is within the golden zone between the upper and lower limits, then assess oil quality: rub a small amount between your fingertips - it should feel silky smooth. Grittiness indicates a failed filter. I always keep a long-handled flashlight handy to simultaneously check belt tension while inspecting oil. Last year I learned the hard way by focusing only on oil quantity while neglecting darkened oil, which resulted in camshaft wear. Now I've adopted a disciplined routine - performing thorough checks every other Sunday morning until it becomes muscle memory.
