What measures help protect the environment?

The selected combination is effective in protecting the environment because both low-resistance tyres and low viscosity engine oil contribute to reducing fuel consumption and emissions.

Low-resistance tyres minimize friction with the road, which enhances fuel efficiency. This is significant in German traffic regulations as they emphasize eco-friendly driving and reducing pollutant emissions to comply with environmental standards.

Low viscosity engine oil allows the engine to operate more smoothly, which also improves fuel efficiency and reduces harmful exhaust emissions.

In contrast, air-conditioning systems, while they have benefits for passenger comfort, do not directly contribute to environmental protection in the same way. They can increase fuel consumption, which is why they are not included in the correct combination of measures intended to safeguard the environment. Thus, selecting all relevant options is crucial for implementing effective environmental protections in driving practices.
