What are the reasons for the high fuel consumption of Polo?
2 Answers
Reasons for the high fuel consumption of Polo: sensor damage, increased carbon deposits in the engine, and engine wear. Detailed explanation of the reasons: There are damaged sensors near the engine, such as the water temperature sensor, oxygen sensor, intake air temperature sensor, air flow sensor, and knock sensor. Increased carbon deposits in the engine and engine wear. Regular maintenance: Cars are better maintained than repaired. Regular maintenance not only reduces the failure rate of the car but also lowers its fuel consumption. During maintenance, regularly replace parts under warranty, such as spark plugs, oil filters, brake fluid, radiator coolant, air filters, power steering fluid, transmission fluid, and fuel filters. Only when the vehicle is in optimal condition can fuel consumption be reduced.
I've been dealing with issues like the Polo in repair shops for years. High fuel consumption often stems from aging engine components. For instance, a severely clogged air filter can restrict airflow, leading to incomplete combustion; spark plugs with excessive gaps result in weak ignition and need replacement; or it could be due to carbon buildup in fuel injectors causing excessive fuel spray or leaks in the fuel system. Low tire pressure also increases rolling resistance. Sometimes, customers neglect regular maintenance, like not changing the engine oil for 50,000 kilometers, causing the engine to become sticky with increased resistance. Additionally, driving in congested urban areas with frequent stops and starts naturally spikes fuel consumption. It's advisable to check tire pressure weekly and clean the filter every 20,000 kilometers.
