How to Measure Car Engine Oil Most Accurately?

Correct method to check the oil dipstick: First, park the vehicle on a level surface because the oil pan is generally irregular in shape, and the markings on the dipstick are based on the upper and lower limits of the oil level in the pan when the vehicle is level. If the vehicle is tilted, the oil in the pan will flow to the lowest point while the dipstick position remains unchanged, resulting in an inaccurate oil level measurement. Steps to check the oil dipstick: 1. Locate the handle: Prepare a tissue before inspection, then find the handle of the oil dipstick in the engine compartment. 2. Wipe clean: Pull out the oil dipstick and use the tissue to thoroughly wipe off the oil clinging to the dipstick head. This will allow you to clearly see the markings on the dipstick. 3. Reinsert the cleaned dipstick: Ensure the entire dipstick is fully inserted, then pull it out again. Note: When removing the dipstick, pay attention to the way you hold it—it can be vertical, tilted, or horizontal, but never upside down, as this may cause the oil on the dipstick to flow backward, affecting the accuracy of the oil level reading. 4. Check the position: Observe the oil clinging to the dipstick to determine the oil level. If the oil level is below the MIN mark or above the MAX mark, it indicates that the engine oil needs to be topped up or there is too much oil.
I've been driving for over a decade, and accurate oil measurement is a crucial maintenance step. First, park the car on level ground to avoid slope affecting the reading. Then, after the engine is turned off, wait five to ten minutes to allow the oil to drain back into the oil pan. Pull out the dipstick, wipe it clean, reinsert it all the way, and then pull it out again to check the oil level, ensuring it's between the minimum and maximum marks. If it's low, add the same type of oil, but avoid overfilling to prevent foaming and engine damage. Regular checks can extend engine life and save on repair costs. I believe it's important to develop a habit of checking every two weeks, especially after long trips. Also, make sure to use the correct oil viscosity; the manual has the recommended specifications—don't mix them up. A level surface is the most reliable; any tilt could lead to misjudging the oil level.
As a new car owner, I was also clueless the first time I checked the oil level, but got the hang of it after a few tries. Park on level ground and turn off the engine, wait a few minutes for the oil to settle. Pull out the dipstick, wipe it completely clean, reinsert it, then pull it out again to check the level - as long as it's between min and max, you're good. If it's too low, add a little oil, remembering to use a funnel to avoid spills. Accurate measurement can prevent engine overheating or part damage. I always keep a dipstick in my car and check before/after business trips. Key points: Dipstick locations vary by model - SUVs may require extra attention to ground clearance. I also monitor oil color - when it turns black, it's time for a change, don't wait for warning lights. Beginners should frequently consult the manual - it's simple and reliable.
