What Causes the Engine to Be Noisy After Refueling?
1 Answers
Car engine becomes noisy after refueling due to the following reasons: 1. Oil issue: The engine oil has not fully lubricated all components of the engine. It takes some time for the new oil to evenly lubricate all parts of the engine. 2. Severe wear: It could also be due to severe wear, and if the engine internals are cleaned, the gaps from wear may become larger. If maintenance is neglected, it might be caused by excessive carbon buildup in the engine (such as excessive carbon in the engine, throttle, spark plugs, etc.), which can be resolved by cleaning at a repair shop. 3. Exhaust pipe leak: When there is a leak in the intake or exhaust pipe, the vehicle produces a louder roar as the exhaust rate increases with acceleration.
