Formula One cars run on petrol, the specification of
which is not that far removed from that used in regular road cars.
Indeed, the FIA regulations state that the rules are "intended to ensure
the use of fuels which are predominantly composed of compounds normally
found in commercial fuels and to prohibit the use of specific
power-boosting chemical compounds.”
All fuel must comply with
strict requirements and prior to each race the teams must supply the FIA
with two separate five-litre samples for analysis and approval.
Additional samples can then be taken during the event to ensure that
there is no discrepancy between the fuel being used and that previously
supplied in the samples.
