As of tomorrow there will no longer be any Sunco Ultra 94 octane sold in NY. The mtbe's used have been declared illegal in NY and the best you will be able to do is 93. At least that is better than in California where we could only get 91.
JPS Europa said:So does anyone know what they are replacing the MTBE with? I thought that there was a Federal requirement to have an oxygen bearing component in the fuel mixture to create a leaner burn. I suppose it would help with knock resistance as well. I assume that they will use methonal...or did the EPA reg go away once they found out that MTBE pollutes the water table? Does anyone know why the companies used MTBE instead of methonal in the first place? I suppose I could research this myself, but I admit my laziness. I do know that the fuel lines on older cars will have trouble at some level of methonal content; don't remember the ratio.

Problems with these blends include poor solubility in gasoline in the pressence of water; toxicity; an energy content about half that of gasoline; high latent heat of vaporization and oxygen content which contribute to poor driveability; incompatibility with many commonly used metals and elastomers; blending effects on gasoline volatility which may force the displacement of large volumes of butane. Some of these problems can be partially reduced by using cosolvents such as TBA or isobutanol."
