How to solve the high fuel consumption of old CRV?
3 Answers
Solutions for high fuel consumption in old CRV: 1. Use high-quality fuel: When the fuel quality added to the car is too low, the fuel and mixed gas cannot fully combust in the engine, leading to partial fuel waste and increased fuel consumption. Using high-quality fuel can help reduce fuel consumption to some extent; 2. Change driving habits: When driving too aggressively, the engine speed tends to be higher, which can overload the engine and increase fuel consumption. It is necessary to adopt a gentler driving style, learn to brake early and start slowly; 3. Clean carbon deposits in time: When the engine carbon deposits are too severe, fuel cannot be transported normally, leading to increased fuel consumption and weakened power. It is important to clean the engine carbon deposits promptly; 4. Reduce the car's weight: When the car is too heavy, it increases the burden on the engine, resulting in higher fuel consumption.
I've been driving an older CRV for several years and have also experienced high fuel consumption. The first step is to start with maintenance. Check the air filter and replace it promptly if it's dirty—it's inexpensive and something you can do yourself. Insufficient tire pressure increases resistance; I check mine monthly, keeping it between 2.3-2.5 bar. Clean carbon buildup from the throttle body, either using additives yourself or having a small shop handle it. During daily driving, avoid sudden acceleration and braking—maintaining a steady speed of 60-80 km/h is most fuel-efficient. If the issue persists, the oxygen sensor might be aging, affecting fuel efficiency, so it's best to visit a professional repair shop for diagnosis and replacement. With regular maintenance like this, my fuel consumption dropped by over 15%, and the car's lifespan also improved.
As a frequent driver, I think the high fuel consumption of the old CRV needs to be addressed. Start by changing driving habits, such as remembering to accelerate smoothly, reducing sudden braking, and using cruise control more often when driving slowly in the city. Regularly changing engine oil and air filters is simple and inexpensive to do yourself. Insufficient tire pressure can waste fuel, so check it monthly and maintain it at 2.5 bar. Cleaning carbon deposits from the fuel system and using a reliable cleaner can save hassle. If fuel consumption remains high, check the spark plugs or oxygen sensor and consult a professional to avoid unnecessary expenses. Paying attention to these points can save a lot on fuel costs and improve safety.
