 Hotshot's secret, Stiction Eliminator, will improve your performance in fuel economy. For proof, we engaged the Ohio State University Center of Automotive Research to conduct an EPA-certified fuel economy test with Stiction Eliminator on a FedEx truck, a 2006 P500 Freightliner with 247,000 miles. The test showed a 3.6% increase in highway-driving fuel economy from Stiction Eliminator, an oil additive.
