Mid-1942 on play testing the house oil rules, with the war in the Pacific in full swing. The tweaking proposed in the last post is working well, and clearly oil plays its role in strategic decision-making without having to do the "staff officer work". Although the way to reproduce the impact of oil is somewhat different, the end result is very similar to the standard rules in terms of setting strategic priorities, decision-making and level of action for the various powers.
So here is the refined proposed house rules for oil:
1. Oil rules are still turned off on MWIF.
2. A manual count of actions is used instead for determining oil consumption, for each power, as follow:
a. Each Air and Naval action consumes 1 oil;
b. Each Land action of smaller powers (IT, FR, CH) consume 0.5 oil;
c. Each Land action of larger powers (GE, CW, USA, USSR, JP) consume 0.75 oil;
d. Combined (including “super combined”), and Pass do not use oil.
3. At the production phase:
a. for each power, oil consumption is counted based on action choices (rounded down for smaller powers (IT, FR, CH), and rounded up for larger powers (GE, CW, USA, USSR, JP)) and oil production sites have to be turned to “idle” and / or saved oil be deducted from the manual record to match oil consumption.
b. as well, each power can save oil points as per standard oil rules, but it has to be done manually by turning to “idle” one oil production site for each oil saved, and then record it
(Note: unused oil from site already idle can be saved/consumed as per standard oil rules).
4. No power can voluntarily spend more oil than available in production sites and saved oil combined.
5. If a power exceeds its allowable oil capacity because of enemy actions (loosing sites by combat, loosing convoy, strategic bombing of oil production sites, end of trade agreement), then it is in “oil debts”, in which situation a power has to reduce its non-oil resources as per following formula, for EACH over-spent oil point:
a. During the production phase, count the number of non-idle factories, and multiply by 20% (rounded up)
b. Turn to “idle” the same amount of non-oil resources for that turn. For example, if China has 7 producing factory, then it has to put on idle 2 more non-oil resources (1.4 rounded to 2), while Germany with 28 factories producing would have to put 6 more resources on idle (5.6 rounded to 6).
6. One unavoidable variation, there is no bombing or capture of saved oil, but oil production sites can be bombed as per standard rules. It is assumed that oil is stored in a multitude of spots.
