Carburetor efficiency question..

Well here's my first and probably only post.

Now, I don't have the most efficient vehicle ever made, but I bought it because it meets 2 conditions..:

1)It's 4x4
2)It gets decent mpg

The Suzuki Samurai

In the summer I've been getting about 30 mpg on the highway and almost as good in the city. It's has a 2 barrel carburetor, with a single primary and a single secondary.

***So my QUESTION is this:

Will an equal throttle position in different gears (4th or 5th) ALWAYS equal the same mpg?

I'm wondering this because I'm thinking the higher RPM can suck the fuel/air in faster and even though the valve is open the same amount, it gets sucked through it faster, resulting in more fuel burn.

I also have a vacuum gauge ready to install. With this, will I choose 4th or 5th depending on the condition (hills or headwind) based on which ever gear gives the highest vacuum?

Thanks.
