What are the reasons for the high fuel consumption of the older ix35?

[SanRichard]

The reasons for the high fuel consumption of the older ix35 are: Avoid sudden acceleration while driving, as it can cause incomplete combustion in the engine, leading to unutilized fuel being expelled. During sudden deceleration, the fuel in the engine's combustion chamber decreases while the air increases, generating a large amount of hydrocarbons, which also results in increased fuel consumption. Below are some related tips: 1. Check tire pressure: Ensure the tire pressure is adequate, inspect the degree of tire wear, and determine if new tires are needed to enhance friction and reduce fuel consumption. 2. Replace spark plugs: Check if the spark plugs need replacement, as damaged spark plugs can reduce ignition energy, slowing down the vehicle's acceleration.
