STP has launched their latest generation Complete Fuel System Cleaner.

The most advanced fuel additive available is stronger, better and more efficient than its predecessor and is specially formulated to clean the entire fuel system, with the emphasis on all fuel delivery components and all combustion areas.

Simply adding a 400ml bottle of STP Complete Fuel System Cleaner to a full tank of fuel every 4,000 miles helps restore the vehicle's fuel system to optimum operating condition by removing power-sapping deposits from fuel injectors, carburettors, intake valves, combustion chambers, valve guides and ports, cylinder heads and piston crowns.

Benefits include better fuel economy, improved starting, reduced octane requirement, restoring lost horsepower, and lowering of exhaust emissions.

Derivatives are available for both petrol and diesel engines - normally-aspirated and supercharged/turbocharged - and are safe for use with all catalytic converters.
