Court documents reveal that Royal Dutch Shell premium brand motor oil, Pennzoil-Quaker State, is mired in another false advertising scandal.

A New Jersey Court case against Shell Oil Products alleges predatory conduct by the oil giant against a small company, Wexco Industries. Allegations against Shell include fraud and misrepresentation.

For several years, Shell Oil Products, a division of Royal Dutch Shell Plc, has been involved in a sleazy fraud perpetrated on customers at an oil lube chain in Illinois.
