Why does the Tharu have such high fuel consumption?
2 Answers
The reasons for the Tharu's particularly high fuel consumption at startup are as follows: because it displays instantaneous fuel consumption. The moment of starting is in 1st gear, and the clutch is semi-engaged, which means the transmission ratio from the crankshaft to the wheels is at its maximum. Instantaneous fuel consumption is calculated based on the instantaneous fuel injection volume and wheel speed, so the instantaneous fuel consumption at this time is the highest. Here are some methods to reduce fuel consumption: 1. Clean engine carbon deposits: Excessive engine carbon deposits are a significant reason, mainly due to the use of inappropriate fuel. It is recommended to add a certain amount of cleaning agent when refueling, and after cleaning, drive at high speed for a while to help increase exhaust volume and allow stronger airflow to remove larger carbon deposit particles. 2. Check the oxygen sensor: As an internal control unit of the car, the oxygen sensor mainly monitors the fuel-air ratio of the engine. Once it is damaged, it will cause an imbalance in the fuel-air ratio, leading to a sudden increase in fuel consumption. After the oxygen sensor is damaged, the exhaust pipe will emit darker-colored exhaust during driving, and the oxygen sensor should be replaced at this time. 3. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced regularly. If they are not replaced for a long time, they will become dirty and affect performance, sending incorrect information to the engine control unit, resulting in incomplete fuel combustion and increased engine carbon deposits.
As a Volkswagen Tharu owner, I find high fuel consumption quite common, mainly due to the significant impact of driving habits. When driving in the city, sudden acceleration or hard braking causes fuel consumption to spike rapidly; maintaining a steady driving style saves a lot of fuel. Using the air conditioning also adds to the burden—running the AC in summer can increase fuel consumption by about 10%. The Tharu's heavy body and high drag coefficient mean lower fuel consumption at highway speeds but higher consumption in low-speed city driving. I recommend trying the Eco mode and avoiding unnecessary sharp turns and rapid acceleration. Additionally, regularly check tire pressure, as low pressure significantly increases rolling resistance. In short, developing good driving habits can reduce fuel consumption, so don't worry too much.
