Two automotive aftermarket products, an Oil Additive and a Specialized Jumper Cable were tested. The oil additive was tested to determine its effects on fuel economy, horsepower, and exhaust emissions while the specialized jumper cable was compared to the operation of a traditional jumper cable. The results indicated that the oil additive had no significant effect on fuel economy, horsepower, or exhaust emissions, and that the specialized jumper cables did not match the performance of a traditional jumper cable.
