According to the EPA 61 FR 3832 - Prohibition on Gasoline Containing Lead or Lead Additives for Highway Use
EPA has historically defined unleaded gasoline as gasoline
that is produced without the use of any lead additive and that contains
no more than 0.05 gram of lead per gallon. EPA interprets section
211(n) this way for the following reasons. The regulatory definition of ``unleaded gasoline’’ also
contains a cap on the amount of phosphorus, see 40 CFR 80.2(g), but
the phosphorus cap is not relevant to the discussion of section
211(n). Unleaded gasoline that was produced without lead additives may pick
up trace amounts of lead as it passes through refinery and transport
systems that had previously contained leaded gasoline.
This is the same limit Formula 1 has for its fuels. Formula 1 fuel is unleaded fuel.
Formula One hasn’t used leaded gasoline since the 90’s.
The fuel they use is actually very similar to the gas that anyone can buy at the pump.
