In south east louisiana. It's pretty humid out here. I guess there are at least 15 to 20 people that have diesels here at work. Probably 4 or 5 had to get injector work done. O
That is what I figured. Based on my professional experience dealing with things like this with fleets on a national level for a manufacturer, it probably was either their fault for not maintaining their engine or the fault of the fuel station where they got their fuel. Just about every time multiple people in an area have injector issues with different diesel makes in a humid area then it almost always is water contamination which is not the fault of the engine manufacturer.
If it was water contamination, then they either got water in their tank two ways. One way is from a fuel station that either has a clogged breather filter or no filter at all (which is the case for many of you mom and pop stores). As the fuel gets used and goes down, the space void is replaced by hot and humid air. At night when it cools, the humid air condensates into a layer of water on top of the diesel. Breather filters are suppose minimise this effect, but many times they do not get changed in proper intervals if there's even one at all. The second way is the very same thing happening in your tank. As you use fuel, it pulls humid air in which condensates at night.
If this water gets to the injector then you will have what is called an injector blow out among other things and is NOT the fault of the diesel manufacturer. This is due to the owner not maintaining the engine like he should.

Most diesel trucks have fuel/water seperator filters with a drain valve for this very same issue. If the sensor detects water in the filter then you are suppose to drain it from the filter which literally takes less than three minutes to do in the 2007.5+ Rams. If I were in a hot and humid climate then I would do this every 5,000 miles or so depending on usage just in case one of those sensors fails to detect water. If I was in an old truck that did not have a fuel/water separator filter, then I would invest in one of the many aftermarket ones that are available.
There's a reason why diesel manufacturers supply a diesel supplement along with the owner's manual for these diesel trucks and it is not their fault if the owner chooses not to read them to know how to properly maintain them. But of course, it will never be the truck owners fault and they will swear up and down that they maintain the truck even though the proof that they didn't is shown in how the injector failed.
