S!LENZ!O

The Challenge: 
S-Oil wanted to show it had a mission: to save oil. They knew South Korea's capital had some of the highest gasoline consumption in the world. What's more, car use was increasing, petrol costs rising, and parking spaces scarce. Every day, a Seoul driver wanders for 500m to find a space. Over a month, this comes to 15km of driving. People were using around a litre of gas just trying to park.

The Idea: 
What if we could tell people there was a parking space right here? With HERE balloons, S-Oil did exactly that. They set up a bright yellow balloon in each space. The balloon falls when a car parks in the space, and rises again when the car leaves. Drivers could see the colourful balloons from far away and spot empty spaces. Quick parking means saving time and saving oil. That means happier drivers and a healthier planet.

Did it move? 
The campaign certainly helped drivers to save oil. In just one day, 700 cars used 23 litres less oil. Over a whole year, they saved much more. S-Oil had engaged with people: now they knew it was a company that cared about saving oil. They even put the balloons on their own gas stations. People now thought about cutting gas costs when they thought about S-Oil.
