What Happens If You Add Low-Quality Gasoline?
1 Answers
Cars filled with low-quality gasoline may exhibit the following symptoms: difficulty starting or even failure to start; engine shaking at idle after starting; noticeable body vibration; foul-smelling exhaust gases; noisy valves; poor acceleration and high fuel consumption; gear shifting with impact. The vehicle maintenance plan after adding low-quality gasoline is as follows: 1. If the vehicle can currently drive normally without symptoms, completely drain the remaining fuel in the tank, refill with high-quality gasoline, clean the fuel injectors, clean the combustion chamber, and replace the fuel filter. 2. If the vehicle drives normally but the engine shakes slightly at idle, completely drain the remaining fuel in the tank, refill with high-quality gasoline, clean the throttle body, clean the fuel injectors, clean the combustion chamber, and replace the fuel filter and fuel pump. 3. For vehicles that are difficult to start, fail to start, have engine shaking, poor acceleration, gear shifting impact, or noisy valves, stop driving immediately and request assistance from a 4S shop. Measure cylinder pressure; if the cylinder pressure is normal, disassemble the cylinder head for cleaning, completely drain the remaining fuel in the tank, refill with high-quality gasoline, clean the throttle body, clean the fuel injectors, clean the combustion chamber, and replace the fuel filter and fuel pump.
