Q: Why do the 104+ Octane Boost products say “For Off Road Use Only” on the label?
A: These formulas are not registered with the EPA for on-road use, so we are required to label both the 104+ Octane Boost and 104+ MAXIMUM Octane Boost products for “Off Road Use Only”. However, both 104+ products are safe to use in ALL vehicles, and will not harm catalytic converters or oxygen sensors.
