Upgrade & Speed Up
You can use VIM or its equivalent amount in Oil or VeOil to upgrade your oil field. Once upgraded, you can activate the boost feature to enhance your OIL output rate and earn more from the increased OIL production. The oil output bonus is directly proportional to the oil field's level. The increased output can be influenced by random events, and the bonus for boosted oil fields will adjust once the random event countdown concludes.
To upgrade the oil field, you'll need to consume VIM. The amount of oil needed to trigger the boost is based on the oil field's current output (measured in days). For instance, the boost cost for a level 2 oil field is equivalent to 3 days of its output.
