What is the amount of oil from the upper limit to the lower limit on the dipstick?

Generally, the amount of oil from the upper limit to the lower limit on a car's dipstick is about 1.5L. The function of the dipstick is not only to check the level of engine lubricating oil but also to allow mechanics to detect many working dynamics of the engine by inspecting it. Proper use of the dipstick plays a crucial role in extending the engine's lifespan. First, locate the position of the oil dipstick. The oil dipstick is usually located near the engine, either on top or on the side. A distinctive feature of the dipstick is a pull ring, making it easy to identify. Pull out the oil dipstick. When checking the car's oil level, ensure the vehicle is cooled down. If you've just driven the car or the engine is running, the measurement will not be accurate. Clean off the oil residue. After pulling out the dipstick for the first time, wipe it clean with a clean tissue, then reinsert it. Pull out the dipstick a second time to check the oil level. If the oil level is between the upper and lower limits, it indicates the oil level is normal. The upper and lower limits are usually marked with scales, clearly visible as the dotted area.
How much oil is there between the upper and lower limits on the dipstick? This is a question I often encounter while driving. The range between MIN and MAX is indeed the ideal level. From my experience, the difference isn't fixed, generally between 0.5 liters to 1 liter. For example, a small sedan might have about 0.6 liters, while my SUV has around 0.8 liters. It's best not to let the oil level go below MIN or above MAX—otherwise, big trouble arises. Too little oil causes engine overload and wear, and increases fuel consumption; too much oil leads to foaming, poor lubrication, and affects piston movement. I check it weekly on a sunny day on level ground: after parking and turning off the engine for 5 minutes, pull out the dipstick, wipe it clean, reinsert it, then check that the oil stain line is centered. Maintaining this habit for years has kept me trouble-free and saved on repair costs. When topping up oil, always use the manufacturer's standard oil—avoid mixing brands, as this is more important.
The MIN to MAX marks on the dipstick indicate the safe oil level range, with the volume difference varying by vehicle model. Based on my experience with several cars, the oil quantity required to go from MIN to MAX typically ranges between 0.4L to 0.8L. For instance, compact cars may need around 0.4L, while diesel engines often require slightly more at approximately 0.7L. This engineered clearance ensures smooth engine operation - insufficient oil level causes oil pump starvation leading to premature component wear from friction, whereas overfilling makes the crankshaft aerate oil, creating bubbles that compromise cooling. For accurate measurement, check when cold: park on level ground, wait 10 minutes after shutdown, wipe the dipstick clean, reinsert fully, then read. The ideal level is midway between marks. Regular maintenance prevents these issues and extends engine lifespan.
