Are All Cars Over 10 Years Old Fuel Inefficient?
1 Answers
Whether cars over 10 years old are fuel inefficient depends on specific circumstances. There are many factors affecting a car's fuel consumption, including external and internal factors. External factors: Driving habits, road conditions, vehicle load, tire pressure, and other factors can all influence a car's fuel consumption. Internal factors: What truly affects a vehicle's fuel consumption is how many strokes the engine makes within a specified time and distance. Strokes refer to the engine's RPM. Therefore, only when both displacement and RPM are low will the car's fuel consumption be lower. These factors are interrelated. Solutions for high fuel consumption: First, check the tires. If the tire pressure is insufficient, fuel consumption will increase. If the tire pressure is normal, inspect the tire wear. Severe tire wear can cause slipping, which also increases fuel consumption. Next, examine the engine. If there is excessive carbon buildup in the engine in a short period, it may be due to using substandard fuel. Add a certain amount of cleaner when refueling. If the effect is not noticeable, it indicates significant carbon buildup in the engine, which requires cleaning by a 4S shop or repair shop. Finally, if the oxygen sensor is damaged, it will disrupt the air-fuel ratio in the engine, leading to abnormally high fuel consumption. Replace the oxygen sensor as soon as possible.
