 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. The complete report from OSU is available for download at hotshotsecret.com. That's proof.
