If someone has 2 oils tiles that might mean 2 battle ship and 4 tanks. If their rival has 4 oil tiles that would me something like 4 battle ships and 8 tanks. (I'm assuming 3 units per resource). The empire with the most resources has the upper hand hence the wars over oil late game.
It might mean pure dominance of the first one to discover and access oil as well.
Wouldn't that player be forced to secure as many oil resources as possible, and if only for the sake of keeping the others away?
The first tank would be used to sit on a not yet acquired oil resource, the rest of the army would help protecting it and in the meantime the home production creates more tanks, which will lead to more "secured" oil resources.
In Civ4, many people complained about "uber-units" (or suggestions which would have led to such units), while there still would have been the chance to counter them by mass attacks of weaker units.
The combination of 1upt and less units in total might make this much harder and therefore should require quite a sophisticated balancing.
