I don't want to start disagreeing with one of the other scientifically minded posters, but I think you have to think this part through, or maybe explain it a little better. Specific gravity (density) of these common liquids:

Liquid; Specific Gravity (grams per cubic centimeter)
Acetone CH3COCH3; 0.792
Alcohol - ethyl (grain) C2H5OH; 0.789
Alcohol - methyl (wood) CH3OH; 0.790
Diesel Fuel Oil 2D/3D/4D/5D; 0.81 - 0.96
Ethylene glycol; 1.125
Fuel oils 1/2/3/5A/5B/6; 0.82-0.95
Gasoline a; 0.74
Gasoline b; 0.72
Gasoline c; 0.68
Kerosene; 0.78-0.82
Toluene; 0.865
Water. fresh; 1.0
Xylene; 0.87

Found on Engineering Toolbox

All of these liquids (except water) are less dense than water, and gasoline is less dense than ethanol (ethyl) .

ChrisT, if you are talking BTU density, then I will agree with you. If you you are talking density as in mass-over-volume, I must disagree.

If the injectors are tuned for a specific density of fuel, then anything higher or lower in density would have problems being forced through, or dribbling out of, the nozzle of the injector. Please clarify your statement .
