| Post subject: | WAX CRYSTALS in the FUEL?? |
Once diesel fuel forms wax crystals, do those wax crystals eventually turn back into fuel or will they always remain crystals? The reason why I ask is because I haven’t driven my truck (with a full tank of untreated diesel) in two weeks and the temperatures have been in the low teens every night and never reaching above 30 degrees for the day time temperatures for the past week. I haven’t put any additives in. When I parked my truck over 2 weeks ago it was 70 degrees out and I did not anticipate all this cold weather. So now I’m assuming that I have serious wax crystals. I’m wanting to know if the wax crystals dissolve on their own when the temperatures rise or do they always stay wax crystals? Am I going to clog my fuel filter assuming I have wax crystals built up in my tank? If so will PowerService 911 poured in the tank take care of the crystals? THANKS! |

Warm it up and it recovers nicely - should be less of a problem with #1 ULSD - FYI, that is the purpose of the fuel heater in the filter element: liquifies the wax formation - the block heater warms the crakcase oil so there is less drag on the rotating assy, lighter load on the starter motor Power Service and other such additives have anti-gelling formulation - also offer anti-gel separately |

Power Service and other such additives have anti-gelling formulation - also offer anti-gel separately My Cummins has the top-load fuel filter with heater and water-in-fuel sensor, so do you think this is enough to do the trick with untreated fuel? If so, why is there a need to add a winter additive? Normally I use either Amsoil or PowerService fuel deicers. As for my Cummins, I use the Amsoil series 3000 5W30 year round, so I have no problems with cold starting. |

#1 Diesel fuel has anti-gelling properties on the order of -40degF, and that's variable according to geographical location - if you've never experienced any trouble in your area your fuel should be ok - the interval alone is not the problem, it's the lowest projected temperature during the interval that is worrisome |
