An inside look at an engine treated with STP® Complete Fuel System Cleaner.

The Problem

In both old and new engines, impurities in gasoline can cause harmful deposits to form in fuel injectors, intake valves, and combustion chambers – in less than 5,000km – and cause:

  • Lower gas mileage
  • Poor acceleration and lost power
  • Hard starts
  • Auto ignition (knock and ping)
  • Increased exhaust emissions

The Solution

STP® Complete Fuel System Cleaner – our strongest formula – contains powerful detergents to help remove harmful deposits. One tank treatment helps clean the entire fuel system – including fuel injectors, intake valves and even hard-to-reach combustion chambers – to help optimize engine performance.

Scientific Proof

Step inside a test facility as we compare two engines. Both were run for the same amount of kilometers with the same gasoline. Then one engine was treated with STP® Complete Fuel System Cleaner. See for yourself how it can help fight harmful engine deposits to maintain optimum performance.
