We created a quiz where you can win motor oils for a year by answering a few motor oil related questions on the Teboil Diamond website. The quiz can be played in any internet browser or mobile device. The questions are presented one by one, and after each question the game shows the correct answer. The feedback varies according to the player’s answers. The score can be shared in various social media services. You can also take part in the quiz without leaving your contact details and without taking part in the sweepstakes.
