What are the methods and standards for checking engine oil?

[AdalynnMarie]

Here is an introduction to the standard method for checking engine oil: Determining the oil level: Park the vehicle on a relatively level and flat road surface; After parking for 10 minutes, pull out the dipstick and observe the position of the oil between the upper and lower marks on the dipstick to determine whether the oil in the oil pan needs to be added. Remember not to pull out the dipstick immediately after parking to check the oil level in the oil pan, as the result at this time cannot accurately reflect the actual oil level in the oil pan. Do not overfill: If the oil level in the oil pan is already below the lower mark on the dipstick, it is necessary to add oil in time. Unscrew the oil filler cap and add an appropriate amount of the same brand and grade of oil as that in the oil pan. Wait for 10 minutes, then check whether the added oil meets the requirements. The oil level should be between the upper and middle marks on the dipstick. Remember not to add too much oil. If the oil level exceeds the upper mark on the dipstick, the engine will expel oil from the breather and produce blue smoke from the exhaust pipe when operating under this condition.

Checking car engine oil is actually quite simple, and I often do it myself. Park the car on level ground and wait three to five minutes after turning off the engine to let it cool down for a more accurate reading. Open the hood and locate the slender handle marked with the oil dipstick, usually yellow or orange. Pull it out, wipe off the old oil residue with a clean cloth, then reinsert it into the tube. Push it all the way in and pull it out again to check. The oil level should be between the minimum (min) and maximum (max) marks to be considered appropriate. In terms of color, fresh oil is light brown and clear; if it's too dark or has impurities, it's time for a change. The standard is that the oil level shouldn’t be too low to avoid engine part wear, nor too high to prevent oil overflow and seal damage. I usually check after refilling or once a month to promptly determine if topping up or scheduling maintenance is needed. Engine oil is like the car’s blood—it lubricates pistons, cools the engine, and prevents rust. Don’t skip this step to save effort, as neglecting it might lead to higher repair costs later. When handling, wear gloves for safety and avoid touching hot parts to prevent burns. In short, maintaining good oil condition ensures smoother driving and a longer vehicle lifespan.

When it comes to checking engine oil, after decades of driving at my age, it's become second nature. Park the car on level ground, wait about ten minutes after turning off the engine for the heat to dissipate before safely proceeding. Open the hood, locate the dipstick—its position may vary but it's not hard to identify—pull it out, wipe it clean, reinsert it, then pull it out again to check the oil level: it should ideally be between the high and low marks. As for standards, clarity and absence of impurities are most crucial; cloudiness, dark color, or metal particles signal aging. In my youth, cars were fewer but oil issues were significant, and it remains vital today to prevent excessive wear on engine components. I perform routine checks monthly, topping up when necessary but avoiding overfilling. Engine oil serves to lubricate, prevent rust, and cool, impacting overall performance; typically, it should be checked for replacement every 5,000 kilometers driven. Family travel safety comes first—paying attention to such small details can spare you unexpected troubles on the road.

I just learned to drive not long ago, and checking the engine oil is actually quite straightforward. After parking and turning off the engine, wait a few minutes, open the hood to locate the oil dipstick handle, pull it out and wipe it clean, then reinsert and pull it out again to carefully observe the oil mark position: it should be between the min and max lines, indicating sufficient oil level. In terms of color, fresh oil is light brown, and if it turns darker or dirty, it's time for a change. The standard is correct oil level and clear, bright color to avoid engine overheating damage. I check it weekly or before every long trip, just in case. Occasionally, if it's low, I add a bit myself, being careful not to overfill beyond the max line. Engine oil lubricates internal parts to reduce friction, and proper maintenance makes the car last longer. For beginners, frequent checks help cultivate good habits.
