At what temp does diesel freeze?
How cold is too cold for a diesel truck?
The diesel fuel in your fuel tank will become like gel at a temperature of 15ºF or -9.5ºC and you will have trouble starting your engine. Anything below 15ºF / -9.5ºC can and will cause problems for your diesel vehicle.
Use MotorKote Diesel Anti-Gel + Conditioner every time you fill up during the winter. Try to remember to add the anti-gel before pumping the fuel. This will help ensure a good mixture of the anti-gel throughout the fuel.
How long should I idle my truck at startup?
Diesel engines are harder to start in cold weather.
They depend on high temperatures created by compression to ignite the injected fuel. In fact, it is five times harder to start a diesel engine at 0°F (-17°C) than it is to start one at 80°F (26°C).
Do I need to cool the engine before turning it off?
You don't need to cool the engine before you turn it off, but you should cool the turbo if there is one fitted. The turbo runs very hot due to the exhaust gasses passing through it. If you turn off the engine while the turbo is still hot the lubricating oil which is normally fed by the engine oil pump stops flowing.
HOW TO FIGHT FUEL GELLING
To prevent diesel fuel from gelling (or crystallizing) use an Anti-Gel fuel supplement. Anti-Gel drops the freezing point of diesel fuel so it is less likely to freeze in cold weather.
Diesel fuel contains wax causing the fuel to gel, which can block filters.
Wax gives the fuel the combustion speed and compression needed for ignition.
Start using MotorKote Anti-Gel + Conditioner as soon as temperatures approach freezing. The lower the temperature, the more anti-gel needs to be added. Preparation is key. Anti-gel additives will not damage your engine.
Most additives can be added before or after you add fuel. If you add beforehand, you can ensure good mixing.
MotorKote Anti-Gel + Conditioner replaces lost lubricity, displaces water in fuel improves combustion, increases power. Contains no alcohol or harmful solvents, is compatible with all filters and all MotorKote products.
Mixing other winter additive products such as, Cetane Boost, fuel supplements, lubricity modifiers from multiple suppliers can duplicate elements that are not necessary or could negate or nullify each other’s intended purpose.
