Extra Tank (Asphalt 8)

Introduction
The Extra Tank is a powerup in Asphalt 8: Airborne, which doubles the Nitro capacity of all playable vehicles. As with other boosts the Extra Tank powerup is effective a certain time during which all the races a player starts are affected.

Usage
The Extra Tank can be used before the race using a powerup selection before starting a race (if you don't have one, it costs ? to activate one unit). Each unit lasts about ? hours. During this period, every race is started with doubled nitro capacity. Normally the Extra Tank will be empty at the start of the race, but if the Nitro Starter boost is used at the same time with the Extra Tank boost, both Nitro tanks will be full at the start of the race. The Extra Tank powerup can be replenished by winning cups or finishing certain collections.

If the Extra Tank boost is activated, a boost icon will appear in the main menu along with a timer indicating how long the boost will last. A timer will also appear on the Boosts-screen indicating the remaining time of the activated boost.

Trivia

 * In earlier stages of the game (around February 2014, pre Great Wall update era), the Extra Tank powerups received as trophys in the Time-Limited Events lasted for 4 hours. At that time the Tuning Kit would last for 8 hours and Nitro Starter for 2 hours.
