Used a gallon so far and no gel ups! Used in -4 degree weather and no issues.
While Opti-Lube Diesel Fuel Additives are known for protecting your equipment by providing exceptional lubrication to the fuel system, each product has an additional focus.
Opti-Lube Winter Anti-Gel is a multi-functional performance diesel additive. Meaning it does a little bit of everything with anti-gel as it’s focus. It gives protection down to -40°F.* The best diesel fuel additive on the market for cold weather use. Winter Anti-Gel formula does not contain any harmful alcohols.
Don't Forget Winter Anti-Gel Formula is a Preventative Anti-gel.
Preventative anti-gels are used before gelling occurs. To ensure a Preventative anti-gel works properly there is an important rule to keep in mind. Diesel Fuel cannot be at or below the cloud point when Preventative anti-gel is added. There are two reasons for this: (1) If the fuel is cold and wax has begun to crystallize and link, the cold flow additive will not be able to modify the crystals as designed to minimize their growth or alter their morphology, (2) Cold fuel has poor solubility, meaning proper mixing can not occur. The easiest way to ensure your preventative additive is properly mixed and your diesel is not too cold during winter months is to add it at the pump while fueling. When mixed properly the preventive anti-gel will do its job while not ‘falling out’ of solution or separating. Opti-Lube XPD and Winter Anti-Gel contain components that interact with the wax molecules in a way that prevents them from stacking and subsequently forming large, filter plugging crystals.
Let Opti-Lube Keep Your Investment Safe From Gelling This Season.
*Dependant on base fuel and the amount of wax in the fuel. Higher doses of anti-gel may be needed in some areas.
