Commercial fuels were screened for inhibition of material incompatibilities with methanol-gasoline blends. The additives, chosen to provide a diversity of applications and chemical types, were tested at four methanol concentration levels. Corrosivity tests were conducted on metals commonly used in automotive applications. Polymeric materials - elastomers, plastics and cork - were tested for compatibility with the methanol blends. As a result of these tests half of the additives were subjected to further testing in search of optimal application conditions. The completed screening phase indicated three additives which inhibit corrosive effects of the blends on some metals; no effects were noted on the polymeric materials. Optimization continues with a reduced number of additives, materials and methanol blends.
