As the Toyota Camry ages, fuel economy may decrease due to various factors, including wear and tear on engine components, dirty o r clogged air filters, and a reduction in the efficiency of the fuel injection system. The car may also accumulate carbon deposits over time, leading to suboptimal engine performance. In addition, parts like the spark plugs, oxygen sensors, and fuel injectors may degrade, affecting the engine’s ability to burn fuel efficiently.
To prevent a in fuel economy, regular maintenance is crucial. Camry owners should follow the recommended service schedule, including regular oil changes, air filter replacements, and timely engine tuning. For optimal fuel efficiency in Pakistan’s driving conditions, these services should typically be performed every 5,000 to 7,500 km, depending on driving conditions. Regularly cleaning o r replacing spark plugs and ensuring the fuel injectors are in good condition can further help maintain fuel efficiency.
