There are several reasons why a van may be particularly fuel-consuming: 1. Excessive carbon deposits in the engine: The main reason for excessive carbon deposits in the engine in the short term is the use of inappropriate fuel. 2. Long-term neglect of the 'three filters': During vehicle use, the three filters (oil filter, air filter, and fuel filter) must be replaced regularly. If they are not replaced for a long time, it will affect performance, send incorrect information to the engine control unit, lead to incomplete fuel combustion, and increase engine carbon deposits. 3. Damage to the vehicle's oxygen sensor: Once the oxygen sensor is damaged, it will cause an imbalance in the engine's fuel-air mixture ratio, and fuel consumption will definitely increase suddenly.

I often ponder car issues and find that high fuel consumption in vans is quite common, usually due to engine problems and daily maintenance. If there's carbon buildup in the engine, combustion efficiency drops, and fuel burns faster. When tire pressure is insufficient, resistance increases, forcing the engine to work harder while driving, naturally causing fuel consumption to soar. A dirty air filter that isn't replaced can restrict airflow, making the engine run less smoothly. Driving habits also play a role, such as frequent rapid acceleration or braking, especially when vans carry heavy loads, increasing weight and fuel consumption. I recommend checking tire pressure and filter condition monthly, and regularly visiting a repair shop for carbon cleaning or maintenance. Handling these small details well can significantly reduce fuel consumption, saving money and providing peace of mind.

My own van used to be a gas guzzler until I found the root cause. At first, I thought the engine was broken, but it turned out the air filter was completely clogged. After replacing it with a new part, fuel efficiency improved immediately. Low tire pressure was another pitfall – after inflating them properly, the driving became noticeably smoother. My bad driving habit of frequently stomping on the accelerator also contributed; after correcting this, fuel consumption dropped by 20%. Don’t overload when carrying cargo – excess weight strains the engine. Now, I perform basic maintenance every six months, checking spark plugs and engine oil, which has significantly reduced issues. Sharing these tips in hopes of helping others facing similar challenges.

Excessive fuel consumption in vans is commonly caused by factors such as carbon deposits in the engine affecting combustion, underinflated tires increasing resistance, and clogged filters. Aggressive driving or frequent braking also wastes fuel, especially when the van is overloaded. It's recommended to first check if the tire pressure is appropriate and try replacing the air filter. Drive more steadily, avoid sudden acceleration, and don't overload when carrying goods. Paying attention to these small details can save a significant amount of money and be more environmentally friendly.

I have a van at home used for hauling goods, and recently the fuel consumption has been quite high. I'm worried if I've been neglecting some things. Low tire pressure can significantly increase fuel consumption, and a dirty air filter should be replaced promptly; otherwise, the engine won't get enough air and will burn fuel inefficiently. Overloading also makes the vehicle work harder. It's recommended to first check the tire inflation and clean the air filter yourself—don't delay major repairs. Paying attention to these small things daily is low-cost and yields quick results.
