Consideration is being given currently to making large quantities of methanol from corn, grain, or coal. Methanol is desirable as a motor fuel because of its high octane quality and, even more impressive, as an additive to "boost" gasoline's octane quality. A test program conducted with six 1971 cars to study the effect of 10% methanol on fuel economy and driveability showed that the use of methanol can be beneficial if air/fuel ratios are properly selected. At 14% lean methanol showed better driveability, better thermal efficiency, and much lower carbon monoxide and nitrogen oxide levels compared to gasoline running 5% lean. Methanol is not a useful additive for existing unmodified cars, however. It could be used effectively in special vehicles designed to handle the corrosion, water absorption, and vaporization characteristics of its combustion. The cost of manufacture and distribution in a separate system that overcomes the water sensitivity problem will determine the extent of methanol's use.
