    Important notes regarding 2020+ Duramax 6.6L

    Duramax Manufacturer Service bulletin (not related to our filter) mentions many are experiencing oil loss after pulling heavy loads or traveling long distance. Oil loss is due to breather tube drawing in excessive oil that is building up in that part of the engine. Some dealerships are offering a breather tube upgrade to resolve this problem. If you have not received a breather tube upgrade by the manufacturer then we recommend returning your oil through the oil drain plug (select that option when ordering). If you received the breather tube update then our oil filler cap will be the best option to return your oil. This only applies to Duramax engines from 2020 to newer. Questions?
