To change the oil on a Z246i ZT riding mower, first ensure the engine is cool and then remove the oil fill cap. Locate the oil drain plug underneath the mower, place a suitable container underneath, and remove the plug to drain the old oil completely. Once drained, replace the drain plug, add new oil through the fill cap, using the recommended oil type and quantity, and then check the oil level with the dipstick.
