Why does the Yidong XT consume more fuel the longer it is driven?

[OConnor]

This is due to excessive carbon buildup in the car's engine. Below is relevant information about the Yidong XT: 1. Introduction: The Yidong XT is a sedan model under Changan Automobile's product lineup. 2. Exterior: The Yidong XT features an 'Angel Wing' front grille design, where sharp lines seamlessly connect with the full-bodied surfaces. The creative combination of fiber-optic headlights and the grille resembles agile angel wings, exuding a youthful and handsome vibe. Additionally, the sharp surfaces, muscular waistline, and dynamic side profile give the vehicle a powerful forward momentum, evoking a sense of wind-whistling speed.

I've been driving the Yidong XT for over two years and noticed a gradual increase in fuel consumption. The main reasons are frequent use of air conditioning in summer, where the refrigeration compressor consumes additional engine power. In city commuting, frequent stops and starts at traffic lights are inevitable, and fuel consumption is highest when the average speed is below 30 km/h. A few days ago, during a check-up, I found that the right rear tire pressure had dropped to 2.0, 0.3 below the standard, increasing rolling resistance due to the larger contact area. The air filter was last replaced a year ago, and heavy dust accumulation severely affected intake efficiency. Now, I've adjusted my driving habits by anticipating road conditions to slow down in advance and avoiding peak hours when going out, which has stabilized the fuel consumption significantly.

The issue I encountered was a gradual increase in fuel consumption from 7 liters to 9 liters. Upon inspection, three key points were identified: the automatic transmission fluid hadn't been changed for 40,000 kilometers and had become viscous, leading to noticeable gear shift jerks and a spike in fuel consumption. The spark plug gap had widened to 1.3mm, forcing an increase in fuel injection during ignition to maintain power. Consistently purchasing discounted 92-octane fuel at gas stations over the years resulted in severe engine carbon buildup. It's recommended to add fuel system cleaner every two tanks of gas and regularly check the air-fuel ratio with an OBD scanner. After personally replacing the spark plugs with double iridium ones, the fuel consumption has now returned to around 7.5 liters.

The increased fuel consumption of the Eado XT may be related to driving habits. When my car had just passed 100,000 kilometers, I noticed an increase in fuel consumption, mainly due to construction on my commuting route causing 15 kilometers of traffic congestion every day. In this low-speed state, the engine operates inefficiently for long periods. The trunk has been carrying fishing gear and folding chairs long-term, adding an extra 40 kilograms of weight. There was also a slight dragging phenomenon with the brake pads that wasn't addressed promptly, causing the wheels to run with resistance. Now, I've switched to charging at work and commuting in pure electric mode, only using the gasoline car for weekend road trips.

My car's fuel consumption has significantly increased after five years of use. Key areas to inspect are engine-related components: the oxygen sensor is covered in carbon deposits, leading to incorrect fuel injection calculations; aging vacuum tubes with air leaks cause inaccurate air intake measurements. The most unexpected issue was a stuck carbon canister purge valve, which directly released fuel vapors from the tank, wasting gasoline. Additionally, the air conditioning compressor's lack of lubrication increased operational resistance. After replacing these parts, the improvement was noticeable, especially when using the AC in summer—no sudden fuel consumption spikes. For older vehicles, it's advisable to focus on checking these sensors and rubber components.

Fuel consumption changes may result from the accumulation of multiple minor issues. My experience: Winter driving consumes 1 liter more fuel than summer, especially during short trips where the engine doesn't reach optimal temperature before reaching the destination. The aging and detachment of rain deflectors on the side mirrors increased wind resistance. Although I drive alone year-round, having the seat adjusted too far back shifted the vehicle's center of gravity, affecting handling and increasing fuel consumption. At one point, I ignored unusual brake noises, only to later discover a slightly seized brake caliper. Now, I adhere to a strict maintenance schedule—inspecting the chassis and suspension every 5,000 kilometers, promptly replacing wiper blades and windshield fluid to maintain clear visibility and avoid frequent lane changes. Adopting these habits has helped stabilize and control my fuel consumption effectively.
