Report the quality of fuel
Here in Brazil the most gas stations have a bad quality fuel.
This can cause serious damage to vehicles.
We can avoid this scoring the quality of fuel each gas station.
I believe this will be extremely good for those who live in countries with the same problem.

Unrealistic idea. Competitors will mark each other gas stations as bad quality. Also the bad quality could related to many factors and are not static. Just avoid the whole brand.
