STP

The broad STP® portfolio includes gasoline and diesel engine cleaners, injection cleaners, gasoline and diesel additives, filter cleaners and other additives.

STP® products contain effective detergents that help remove harmful deposits.

A single tank treatment helps clean the entire fuel system - including fuel injectors, intake valves and even hard-to-reach combustion chambers - to help optimise engine performance. This protects it and extends its life.

Long experience in the development of lubricants, engine oils and additives makes STP® one of the world's leading manufacturers of operating fluids. STP® has experience in additive manufacturing since the 1950s. Over the years, the STP® brand has grown from garage sales of oil additives to a world leader.

The acronym STP® - Scientifically Treated Petroleum stands for "Scientifically Treated Petroleum". The first product was STP® Oil Treatment, which helped motor oil resist dilution at high temperatures and pressures.
