Winter Anti-Gel Usage

Diesel fuel is notorious for causing fuel system problems during extremely cold weather.  The cold causes the fuel to form waxy solid crystals, which can clog your fuel filter and fuel lines.  This can create real problems for you, causing up to a week of down time and a potentially dangerous situation.


Anti-gel disperses water in the fuel filter which prevents filter icing.  At the start of cold weather, add diesel fuel anti-gel to your fuel tanks to keep the fuel flowing and your engine running efficiently.  It is important that you do NOT mistake fuel conditioner for anti-gel.  Fuel conditioner will NOT prevent your fuel from gelling.

You should always keep at least five bottles of anti-gel on your truck.  You can find it at any of our terminals.

As a general rule, if temperatures are supposed to be below freezing (32 degrees Fahrenheit), use ½ bottle of anti-gel in each fuel tank.  If you are in (or headed to) extremely cold temperatures (below 0 degrees Fahrenheit), you should use a full bottle in each fuel tank.  Make sure to read the instructions on the bottle.  Anti-gel that you purchase on the road will likely require different amounts than what you get from our terminals.If you find yourself on the road without anti-gel, please call at Outside Repair (918-779-6697) for assistance.  

Using too much anti-gel will not damage anything, so better safe than sorry.  If you wait until it is already freezing to add it, there is a good chance it will already be too late. During the winter months, you should use anti-gel every time you fuel your truck.  You never know when your next load might take you north or the weather might change.  Always remember to add anti-gel to your fuel tanks BEFORE fueling so that it mixes properly.

If you notice that your truck is running rough or losing power, there is a good chance that your fuel is beginning to gel.  It is essential that you add anti-gel and fuel to your tanks as soon as possible.  If you do not, you will soon see a CHECK ENGINE light, which is signaling that your fuel system is not functioning correctly.  If this is not addressed immediately, your truck will soon shut down.  If this happens, our only option is to have you towed to the nearest certified Kenworth or Cummins repair facility.

Even if your fuel warms up, your truck still will not start until the check engine light has been reset.  In the meantime, you will have no heat what-so-ever, even from your APU.  This can create a serious safety hazard for you if there are no wreckers that can get to you quickly.

If you have any questions or need to purchase additional anti-gel, please call Melton Outside Repair as soon as possible.
