How to Solve High Fuel Consumption in Corolla?
4 Answers
If damaged, it will reduce ignition energy, causing uneven combustion of the air-fuel mixture, leading to slower acceleration and increased fuel consumption. Ensure spark plugs are replaced on time. Tires can significantly impact driving safety. When tire pressure is below the standard level, it increases rolling resistance and enlarges the tire contact area. Check the tire wear condition. Severe wear reduces friction, which can also lead to higher fuel consumption.
My Corolla's fuel consumption suddenly increased, making every refueling painful, so I decided to tackle the issue myself, starting with the basics. A clogged air filter filled with dust can reduce engine efficiency—upon inspection, it was indeed blackened, so I replaced it immediately, and now the airflow is much smoother. Spark plugs are also crucial; if they're covered in carbon deposits or worn out, they can misfire, leading to higher fuel consumption. Regular cleaning or replacement with the right tools ensures more efficient combustion. Low tire pressure increases rolling resistance, so I bought a tire pressure gauge to check frequently and maintain the manufacturer-recommended levels—don’t overlook this small detail. Additionally, dirty engine oil increases engine load, so I stick to regular full-synthetic oil changes as per the manual, every 5,000 kilometers. After these measures, my fuel consumption dropped from 10L/100km to just over 7L/100km—saving money, being eco-friendly, and the car now runs with more pep.
Having driven a manual Corolla for many years, I always address fuel consumption issues by adjusting my driving habits. Rapid acceleration and sudden braking are the most fuel-wasting bad habits. Now, in the city, I gently press the accelerator and anticipate traffic signals to slow down early. On highways, I frequently use cruise control to maintain a steady speed. I avoid carrying too much weight and keep the trunk free of unnecessary items to reduce the load. In summer, I use the air conditioning moderately, avoiding excessively low temperatures that waste electricity and increase engine strain. At red lights, I turn off the air conditioning to reduce idle time, and I minimize driving for short trips. After developing these good habits, my fuel efficiency has improved significantly, saving me a considerable amount on gas each month. It feels like a responsible approach for both my car and my wallet.
As a money-saving expert, I first used an app to record data and track changes when faced with the high fuel consumption of my Corolla, then made simple adjustments. I choose reliable gas stations to ensure fuel quality and avoid buying inferior gasoline. Keeping the car lightweight by reducing unnecessary heavy items helps lessen the vehicle's burden. Smooth driving without aggressive acceleration and minimizing sudden braking can save fuel. Regularly checking the air filter and engine oil condition, and replacing them myself instead of waiting for major issues, are low-cost changes that helped me reduce fuel consumption by about 20%, while also improving my DIY skills.
