Hi. I am having problems with recent batches. Getting a lot of gunge, waxing in my diesel tank. Can anyone recommend anti waxing agents or other additives?
thanks

Do you have any photos of the "waxing / gunge" to post here?
A picture is worth a 1000 words.
What fuel are you using?
Fuel preparation methods?
Blending ratio?
Biodiesel process?
Looking forward to your response.

Francop ; Biodiesel reacts with itself in an auto-oxidation reaction . I don't entirely understand the reaction , but in some fatty acid carbon chains there are double bonds between adjacent carbon atoms . If I recall correctly a double bond in one fatty acid molecule bonds to a double bond in another fatty acid molecule , so the product , the result , is two fatty acid chains bonded to each other . The biodiesel molecule roughly doubles in molecular weight . The larger molecule has a higher freezing point and different solubility , miscibility properties . You might retrieve a sample of your "wax" solid and determine if it dissolves in dino diesel or not . If it does you might run a tank of petroleum derived dino diesel every so often to clean out your fuel system . And remember to check the fuel filter for obstruction .Last edited by WesleyB; 9 May 2025, 05:37 AM.Comment
