3.3L or so. Honda engine oil is generally added to the middle of the upper and lower limits of the dipstick. Try not to be lower than the middle, because the high temperature of the engine will make the oil dilute at high speed, and if the oil quantity is small, the lubrication effect will be reduced. A little more in the middle is ok, but never increase the upper limit of the dipstick. This is very harmful to the engine. First of all, too much oil will increase the internal rotation resistance of the engine and increase the consumption of fuel and gasoline; Second, too much oil will increase the oil pressure inside the engine, causing extra pressure on the oil seal and piston ring inside the engine, which will easily cause the crankshaft and valve oil seal to be damaged too quickly, leading to oil leakage; Moreover, because of the high pressure and too much oil, the piston ring can't seal the rising lubricating oil in the cylinder, which makes the oil escape to the combustion chamber and causes the engine oil to burn.
