MX3+ Race Fuel is 
designed with more detonation protection than street gas 
provides, yet does not use tetraethyl lead (TEL). It will produce 
good, repeatable power levels in engines up to 12:1 compression ratio, and will 
tolerate more compression in engines with modern, efficient combustion chambers. 
MX3+Race Fuel is a unleaded fuel so it does not contain lead or MMT. It does not harm sensors used in 
fuel injection systems. It is oxygenated at 6.5% increasing combustion efficiency with allows more gasoline to be burned. May not be legal for sanctioning organization racing.
