(a) Vehicles manufactured after January 1986 were built to
comply with Australian Design Rule ADR 37/00 and run
only on unleaded petrol. They generally have computercontrolled
engine management systems, fuel injection, and
are fitted with catalytic converters.
(b) Cars made between 1974 and 1986 were designed to meet
the less stringent ADR 27 and run on leaded petrol, do not
have catalytic converters and generally have carburettors
rather than fuel injection systems.
