What Causes Weak Acceleration and Dullness After an Oil Change?
1 Answers
Here are the specific reasons for experiencing weak acceleration and dullness after an oil change: 1. Incorrect oil quantity: When changing the oil, there is a specified standard. Adding too much oil: The crankshaft requires more effort to rotate, necessitating greater power to drive it, resulting in weak acceleration. Excessive oil may leak into the combustion chamber, leading to rapid oil consumption and engine carbon buildup, which can harm the engine. Adding too little oil: Parts do not receive sufficient lubrication, leading to reduced power. Use the dipstick to check the oil level and add oil to slightly above the midpoint. This ensures adequate engine lubrication without putting excessive pressure on the crankshaft. 2. Oil and engine mismatch: Different engines require different oils. Weak acceleration after an oil change may indicate a mismatch. High viscosity makes it difficult for the crankshaft to rotate, while low viscosity may cause the engine to be incompatible with the oil, resulting in noise. 3. Clogged oil filter or severe carbon buildup: The oil filter should generally be replaced during an oil change. If the oil filter is clogged and not replaced in time, oil will bypass through the relief valve, leading to reduced vehicle power and increased engine wear.
