From the article Bill linked.
"At its low point in 1942, the workforce in Dhahran was reduced to 82 Americans,
84 other foreign employees and about 1,600 Saudis. Despite the war footing, Dhahran was
still able to ship from 12,000 to 15,000 barrels of oil a day by barge to the refinery in Bahrain
to help fuel Britain’s Royal Navy."
It also talks about how later in the war, they expanded capacity to fuel the US navy in the pacific.
So while it certainly seems that Saudi oil production is important enough to include in the game, from what I could glean from that article was that it wasn't shipped to the US mainland.
IMO a perfect solution would be to let the US just have the income from Saudi Arabia if they invest in it, and rename the convoy route as one from South America/Caribbean/ or the US gulf states, and let the Axis subs interdict that.
Just a thought.
That is a very simple change, but the convoy would still effectively come from Saudi Arabia and require the country to have a pro-Allied leaning for it to work, so everything would be the same except it would appear in the US income reports as coming from a different source, which could be confusing.
In terms of where the oil was used, you're right that it probably never made it to the US as that would be inefficient. But convoys are the simplest and best way of representing income gained from a minor and the way the game works, income is effectively centralised under each Major and then they can spend it where they see fit.
The difference here being that it gives the Axis one more convoy to target, which isn't necessarily a bad thing.
