Why is the diesel truck suddenly consuming more fuel?
2 Answers
There are many reasons for sudden fuel consumption, including different driving conditions, personal driving habits, and other objective factors that can affect fuel consumption. Common reasons for diesel vehicles themselves include the following: 1. Insufficient tire pressure or aging tires. If the tire pressure is too low, the contact area between the tire and the ground increases, leading to greater driving resistance and higher fuel consumption. 2. Clogged air filter. The air filter may be obstructed, reducing the air intake and increasing the vehicle's fuel consumption. 3. The fuel injector pressure is insufficient, resulting in poor diesel atomization. 4. Cylinder wear or air leakage, leading to low cylinder pressure and poor combustion efficiency, which increases fuel consumption. 5. In winter, fuel consumption is naturally higher. If winter-specific diesel is not used, or the diesel grade is inappropriate, it can also lead to increased fuel consumption.
Recently, my diesel truck suddenly started consuming way more fuel, costing me hundreds extra for each long trip – it’s heartbreaking. I suspect the injectors might be clogged or worn out; if they don’t spray fuel precisely, diesel gets wasted. Another possibility is a dirty air filter starving the engine of air, forcing it to guzzle fuel. I’ll swap that out ASAP. A faulty turbocharger could also cause this—insufficient airflow spikes fuel consumption. Oh, and low tire pressure or dragging brakes are notorious fuel hogs. Best take it to a proper garage for diagnostics—don’t tinker blindly and make it worse. Saving fuel costs is serious business; fix it early for peace of mind.
