Hello, have my first car now for almost 3 months (VW up 60hp) so I still lack experience values. I depend on the statements of others. Mainly I drive in the city. On 5 or 6 days a week 11km back each, 11km. So now I naturally drive as fuel-saving as possible. I have read, however, that an undertouring driving can be harmful. But what does undertouring mean? So now I have tried everything possible with the new car to reduce the consumption. current driving mode (please do not drag over it, only well-intentioned advice): -Accelerate: Aisle for gear first gear up to 2000 revolutions, the rest after speed from 25 in the 3rd gear, from 37 in the 4th gear, from 45 in the 5th gear or if behind me hit a long time at the traffic light is then I switch the other too much also later -brakes: up to the rudder limit or roll out in the 5th gear (about 37km/h at idle speed) -Switch down: below 40 km/h in the 4th gear, below 30 km/h in the 3rd gear. Aisle, under 20 in the 2nd course In the flowing traffic I drive therefore around 1000 revolutions. My consumption is so at 4.2 l, but of course I have nothing of it in the long term if the engine has to suffer from it. And since I drive almost only in the city traffic, I will blow over the highway every month. Is 1x per month enough? Maybe you can give me tips or have long-term experiences with undertouring driving and possible damage LG Janina
