LOS ANGELES, Calif.—Calabasas-based Fuel Doctor, which makes a small device it claims can increase vehicle miles per gallon by 25 percent, was sued by a consumer who says it did nothing for her car.
Mlissa Drinville filed her lawsuit Wednesday in Los Angeles Superior Court, alleging false advertising and unfair competition.
She is asking for an injunction to stop the company from claiming the device increases fuel efficiency, along with unspecified damages. She also wants to add other consumers to the suit and make it a class action.
