[MetroMPG]

Clean installation. Added to the EM project library.

Probably don't have to say this, but with a vehicle that uses a lot of fuel, changes to "MPG" from mods are going to be relatively small, numerically.

I often see people say things like "only a 1 mpg gain? It's not worth it!". Which of course isn't true with a thirsty vehicle if you look at the volume of fuel saved, rather than MPG figures. (Not implying you'll see a 1 mpg gain.)
