139A SoyShield® All Season

SoyShield® All Season is a concentrated, multi-functional fuel additive formulated for use in all types of diesel fuels, especially low sulfur and ultra low sulfur diesel fuels.

Made from soybean oil, SoyShield® contains an additive package with friction modifying and detergency properties. This unique blend provides excellent wear protection and cleanliness for fuel injectors and fuel pumps. Using advanced anti-wax settling agents and cold flow improver, SoyShield reduces and safely disperses wax crystals from forming and clogging fuel filters and lines.

Further blended into SoyShield® is our proprietary lubricity additive, SynShield®, which prevents fuel system wear and injector scoring for longer component life. 

SoyShield® meets the cleanup and keep clean performance as shown by the Peugeot DW10 Injector Depositing Test throughout the entire fuel system. SoyShield® is registered and meets US EPA requirements for blending into low sulfur and ultra low sulfur diesel fuels. Contains less than 15PPM sulfur.
