Stock-car owner Junior Johnson, stung by NASCAR’s announcement that his drivers used illegal fuel in qualifying runs at Pocono, Pa., in July, said that NASCAR is trying to cover up the scope of the cheating scandal.

NASCAR officials disqualified Geoff Bodine at Pocono minutes after he had won the pole, charging that he had not used Unocal’s special racing gasoline, the only legal fuel. Darrell Waltrip posted the second-fastest time and was awarded the pole.

Now, three weeks later, NASCAR, citing results of a chemical analysis of the fuel used by Waltrip and Neil Bonnett, Johnson’s two drivers, disallowed the qualifying runs of those two.

Johnson claimed that at least seven more drivers were caught using illegal fuel at Pocono but said NASCAR isn’t releasing that information or naming those drivers.

Chip Williams, director of public relations for NASCAR, denied the allegations.
