MX3 is designed for applications that
need more detonation protection than street gas provides, yet cannot use
tetraethyl lead (TEL). It increase power
levels in engines up to 12:1 compression ratio, and will tolerate more
compression in engines with modern, efficient combustion chambers. MX3 does
not contain lead or MMT. It does not harm sensors used in fuel injection
systems. It is also an excellent choice where oxygenates such as ethanol are
limited or banned by the engine manufacturer or sanctioning organization
