If you have installed Duramax injectors on your diesel truck or car, you need to know the right time to clean them so that they can continue working well. The performance as well as longevity of your vehicle largely depends on its fuel. But as time goes by, the performance of your vehicle may start to deteriorate even if you have been using the highest quality of fuel on the market. One of the reasons for this deterioration may be that your fuel injectors are dirty and need to be cleaned.
