STP Diesel Treatment improves lubricity of diesel
STP Diesel Treatment is a fuel additive designed to improve the performance of diesel engines. One of its key benefits is its ability to improve the lubricity of diesel fuel. Lubricity is a measure of a fluid's ability to reduce friction between surfaces, and improving the lubricity of diesel fuel can have several benefits for engine performance and longevity.
The treatment helps to maintain diesel engine performance by keeping fuel injectors clean. Deposits, dirt, gum, and corrosion can build up in the fuel system over time, affecting performance and fuel efficiency. By keeping the fuel intake system clean, STP Diesel Treatment helps to maintain optimal fuel flow and improve lubricity.
Additionally, STP Diesel Treatment provides a thicker cushion between moving engine parts, reducing metal-to-metal contact. This reduction in friction helps protect against engine wear and tear, as well as heat caused by metal-to-metal friction. By improving lubricity and reducing friction, STP Diesel Treatment can help extend the life of engine components.
The treatment is designed to be used regularly, either at or between oil changes. It is added directly to the engine oil when the engine is warm. One bottle treats 6 litres of diesel oil, and it is important to avoid overfilling and not to use it in petrol engines or with low SAPS oil.
Overall, STP Diesel Treatment's ability to improve the lubricity of diesel fuel helps to maintain engine performance, improve fuel efficiency, and protect against engine wear and tear, making it a valuable additive for diesel engine maintenance.
