Is it a problem if the oil dipstick is slightly above the lower limit?

The upper and lower limits on the oil dipstick essentially represent the normal oil level. When the pressure in the engine cylinder rises sharply, it suddenly increases the load on the piston, piston rings, connecting rod, and crankshaft bearings. This load is transmitted and lubricated through the bearings, cushioning the impact load. Hazards of too much oil in a car: Increased fuel consumption—when the oil level exceeds the maximum mark, excessive oil can hinder the crankshaft's operation during high-speed engine operation, increasing engine pressure and affecting engine power, thus raising fuel consumption. Power impact—excessive oil leads to more oil entering the combustion chamber, causing incomplete combustion when mixed with fuel, generating a large amount of carbon deposits that obstruct piston movement, reducing engine power and making the engine sound muffled. Correct method for checking the oil dipstick: After driving for a while, stop the car for 10-15 minutes. Park the car on a level surface; if the ground is uneven, the engine may tilt, causing oil to flow to the lower side and resulting in inaccurate measurements. Pull out the oil dipstick and wipe it clean with a cloth. Reinsert the dipstick into the oil hole, then quickly pull it out again to check the oil level height.
Having driven for over a decade, I can't stress enough the importance of engine oil. Even if the oil level is near the lower mark on the dipstick, it's still usable, but you must keep an eye on it. The engine relies entirely on oil for lubrication, and insufficient oil increases friction between parts, leading to premature wear. I recommend topping up the oil to the mid-to-upper level as soon as possible. Always check the oil when the engine is cold, parked on level ground, and after turning off the engine for ten minutes to get an accurate reading. If you notice the oil level dropping quickly, it might indicate oil burning or leaks in the engine, requiring a professional inspection. Remember, engine repairs can be costly if it leads to cylinder scoring. Developing a habit of checking the oil monthly is crucial.
