A Powerstroke DEF delete is a modification made to diesel engines, specifically the Ford Powerstroke engines, in which the diesel exhaust fluid (DEF) system is disabled or removed. This modification is often done to improve engine performance and fuel economy. While a Powerstroke DEF delete can offer several benefits, it also requires proper maintenance to ensure the longevity and efficiency of the engine.
1. Regular Oil Changes
One of the most essential maintenance tasks after a Powerstroke DEF delete is to regularly change the engine oil. The DEF system in diesel engines plays a crucial role in reducing emissions and improving fuel efficiency. However, removing or disabling this system can lead to increased strain on the engine, resulting in more contaminants in the oil. Regular oil changes will help remove these contaminants and keep the engine running smoothly.

2. Fuel Filter Replacement
The DEF system is also responsible for reducing nitrogen oxide emissions, which means that after a Powerstroke DEF delete, there may be an increase in these emissions. It is vital to replace the fuel filter regularly to prevent clogging and ensure the engine receives clean fuel.
3. Monitoring EGT Levels
Exhaust Gas Temperature (EGT) is an important parameter to monitor after a Powerstroke DEF delete. Without the DEF system, the engine may produce higher EGT levels, which can lead to excessive heat and potential damage to engine components. Monitoring EGT levels using a pyrometer and taking necessary measures, such as installing an aftermarket exhaust system or upgrading the intercooler, can help mitigate any risks associated with increased EGT levels.
