It’s the most advanced STP fuel additive available. Proven on the road and track, it has been specially formulated with a concentrated synthetic deposit control package, which cleans and protects the entire fuel system for peak performance. One treatment helps to restore the vehicle’s optimum operating condition by removing power robbing deposits, which would otherwise result in knocking and pinking, increased octane requirements, lost horsepower, hard starting, engine run-on, poor fuel economy, hesitation, and increased emissions.
