A significant and growing number of cars equipped with catalytic converters are being fueled with leaded gasoline in major Canadian cities. That is one of the conclusions drawn from an early-1978 gas station survey funded by the Mobile Sources Div. of the Canadian Department of Fisheries and Environment. The survey revealed other information relating to this "misfueling" practice: The misfueling rate is age-related and increases after the vehicle's warranty period has expired. In the majority of cases, the misfueled vehicles' inlet restrictors have been tampered with. Full-service stations have a much higher rate of misfueling than self-service stations. In some cases, leaded-fuel pumps have been equipped with substitute filler nozzles which permit fueling with leaded gas without the need for inlet restrictor tampering. The size of the price differential between leaded and unleaded fuel does not correlate well with the observed misfueling rate.
