Why is the Volkswagen Bora consuming too much fuel?

It may be due to low tire pressure. Below is relevant information about fuel consumption: 1. Fuel consumption per 100 kilometers: This refers to the amount of fuel consumed by a vehicle traveling 100 kilometers on the road at a certain speed. It is a theoretical indicator for vehicles. The fuel consumption per 100 kilometers is measured by manufacturers in an objective environment using a dynamometer installed on the vehicle's chassis, converting the obtained values into speed parameters, and then calculating the theoretical experimental fuel consumption data for the model at specified speeds. 2. Road condition fuel consumption: Road condition fuel consumption is a fuel indicator calculated by repeatedly testing the values measured when a vehicle travels on specified roads at specified speeds and times, also known as multi-condition road cycle fuel consumption. The standard specifies that each cycle includes various driving conditions and records driving conditions based on specified shift times, parking durations, driving speeds, acceleration, braking, deceleration, and other indicators in each cycle. The values measured by this method are relatively close to actual values.
My Bora also used to be very fuel-thirsty, and I later realized it was caused by multiple factors. Insufficient tire pressure increases rolling resistance - just 0.3 bar lower pressure in all four tires can increase fuel consumption by 5%. The spark plugs hadn't been changed after 50,000 km, causing reduced ignition efficiency and incomplete combustion. The worst part was my frequent short-distance driving in congested urban areas - the engine would just warm up when I reached my destination, and this cold-engine state is most fuel-intensive. Additionally, I always kept two cases of mineral water and a golf bag in the trunk, and the extra weight was also problematic. I suggest first checking tire pressure and carbon buildup, then optimizing route selection to avoid peak hours, which can effectively improve fuel efficiency.
