燃油

燃油是操作使用内燃机所必需的资源，包括卡车，坦克，飞机和舰艇。

生产

燃油主要是从石油中提炼。每个单位的石油每天可以提炼48个单位的燃油。提炼过程的效能可能通过研究燃油提炼技术来大大提高。战时经济以下的经济法案会降低提炼效率。

合成提炼厂提供一种不需要石油的额外的燃油来源。它们提供基础的每天48个单位的燃油（等价于一个单位石油），但它可以通过燃油和石油提炼技术（最多+250%），大幅提高。它们的生产不受来自经济法案的负面影响。

最后，每个国家的基础燃油生产量都是每天48个单位。

贮存

与战略资源相比，燃油可以贮存起来。这使得一个国家发生燃油短缺时，会过一段时间而不是立即就会对部队造成不利的影响。每个国家的基础燃油储备为50000单位，任何省每一级基础设施等级再追加750个单位。修建 燃油贮存库可以提高每个贮存库10000个单位，但是它们非常脆弱，容易被轰炸或占领。经济法案对贮存量的多寡影响非常大。

当迫使一个国家投降时，能够占据它的燃油贮存量的50%，当并吞时，为25%。

消耗

装备单位的实际燃油消耗量取决于它操作或运行的模式，其相对于正常燃油消耗量的比例会在各个单位的详细信息中显示。如果它们燃油耗尽，其移动和战斗能力会受到严重削弱。

师

一个师如果有任何的一个战斗营拥有消耗燃油的装备，比如卡车，半履带车，坦克和自行火炮，它就需要燃油。在单位选择面板上，这些师的名字边会标有油桶。一个师每天的实际燃油用量是它统计信息里用量的12倍。当处于空闲，战略重新部署和海运期间，没有燃油消耗。行进时战斗的燃油消耗会加倍。

Each division has an internal storage lasting for 4 days of continued use. As long as the country has fuel available, they can refill via the supply system, at twice the normal consumption speed. If their supply zone is overloaded, the fuel flow is reduced and eventually stops at 50% overload. For example a supply zone providing 20 supply containing units requiring 30 supply will deliver no fuel at all to those units as other supplies take priority. When divisions fall below 25% of their internal fuel storage, they start to suffer increasing penalties, finally getting reduced to 40% movement speed and 10% battalion combat stats when no fuel is left. Training divisions earn no experience after running out of fuel.

Aircraft

All aircraft use fuel while on missions (except rocket interceptors which don't run on oil-based fuel). The effective fuel use per day and aircraft is 8.4 times the nominal fuel usage shown in the wing's details. When only operating at day or night, the fuel consumption is reduced accordingly.

Nominal fuel usage	Daily consumption of 100 active aircraft
0.2 (fighter, heavy fighter, CAS, NAV)	168
0.3 (TAC)	252
0.4 (jet fighter)	336
0.6 (strategic bombers)	504
0.7 (jet tactical bomber)	588
1.4 (jet strategic bomber)	1.176

Some mission types have non-standard fuel consumption:

• interception mission: 20%
• kamikaze: 75%
• port strike: 120%
• training: 80%

When running out of fuel, air missions receive a 75% mission efficiency penalty.

Ships

The effective fuel use per day is 2.4 times the nominal fuel usage shown in the ship's stats. Ships have particularly high fuel consumption, so their mission assignments need to be carefully considered. Ships consume twice as much fuel while in combat but otherwise don't consume fuel when staying in position (whether in port or at sea). This includes task forces on naval invasion support and strike force missions while they have nothing to do. The training mission only uses 80% fuel.

When ships run out of fuel they receive penalties of up to 75% to speed and range and 50% attack.
