Excessive White Smoke
Problem: Several things could be causing white smoke in your 6.0 Powerstroke:
Cause: Stiction in the injectors
Solution: Treat with a full dose of Stiction Eliminator to clean out your injectors.
Cause: Poor fuel quality
Solution: If you suspect poor fuel or water in fuel, treat with Diesel Extreme and change fuel filter.
Cause: Failing EGR cooler
Solution: Check the EGR cooler.
White smoke can be caused by a couple of different things. If there is only smoke on start up, which goes away when the truck gets warmed up, it is likely unburned fuel. An injector with stiction can cause an issue where the combustion temperatures are not high enough to completely burn the fuel. Using one full dose of Stiction Eliminator to clean out your injectors will give your truck a boost when cold. Poor fuel quality can cause water in the fuel without you realizing it. If the “water in fuel” light is on, or you just suspect water in the fuel, use Diesel Extreme to clear out the system and change your fuel filter.
