Why does my 2.0 engine consume 7.4-7.8 liters on the highway at 130-140 km/h and 8 liters on national roads, while it only consumes 6-7 liters?

Does this car consume a lot of fuel on the highway? How many liters per 100 km on the highway?

Is it normal for my 2008 Touran manual 2.0 to run at 3500 RPM at 120 km/h and 4000 RPM at 140 km/h on the highway?

I'm a newbie... Can I ask how to drive gently to save fuel? I have a 2013 automatic GLS 2.0, and I can only get about 450 km per tank (-̩̩̩-̩̩̩-̩̩̩-̩̩̩-̩̩̩___-̩̩̩-̩̩̩-̩̩̩-̩̩̩-̩̩̩). I haven't been on the highway, usually just driving in the city at around 50/60 km/h, and on national roads at 80 km/h, never accelerated to 100 km/h...

How do you guys manage to get 6 or 7 liters per 100 km? I filled up until the pump clicked off, drove 140 km, and already lost one bar of fuel. It's consuming more than 10 liters per 100 km 😭😭😭

I've heard this car handles well. How does it perform on the highway? Is it stable around 130 km/h?

Others are saying that the Tank's fuel consumption is between 6 to 7 liters, but why is my car consuming over 11 liters even though it's just over 5,000 kilometers?

I'm torn. What are the limitations of the 8-seater version 130 on the highway? Can someone knowledgeable help me out? Thanks, everyone! 🙏🙏🙏

How many kilometers can the Zeekr 009 run at a highway speed of 120-130 km/h?

I have a 2007 Skoda Octavia with a manual transmission. It's really fuel-efficient on the highway, especially stable at 120-140 km/h. Even in rural areas, it only consumes about 4-5 liters per 100 km at 80 km/h. I checked the chassis the other day, and it's not rusty at all. I'm thinking about replacing it, but I'm really attached to it.
