I'm pretty sure it's not the fuel but I guess you never know. When traveling I was obviously getting diesel from unfamiliar sources but they were high volume stations. I don't use additives so I know that's not it either.

It looks like the shop is not able to get to my truck until early next week. I guess we'll see what they say. Hopefully they know what they're doing. ;)

Wouldn't fuel with enough water to ruin injectors trip the water in fuel warning?

Yes and no.

If an unscrupulous station owner has some water in his tanks all he has to do is dump some emulsification agent in his tanks to deal with it.

Also some ignorant truck owners dump additives in their tanks not knowing what they contain or what they do. If they happen to get ahold of an additive that has an emulsification agent in it the water will slide right through the filter like no filter at all.

Another possibility is that you got some gasoline into the system. There would be no warning light but the damage is just as serious as water.

I was thinking the same thing. Bad fuel. Mind you, not arguing at all with what your mechanic says.

But, my only experience with white smoke was on my 2006 Dodge Ram w/Cummins. Got bad fuel and sure enough, white smoke. Cleared up after I refueled at another trusted source for fuel.

That's really sad that a 2014 already needs injectors. Maybe you got some bad fuel or the fuel filter/separator isn't doing it's job?

Ask your insurance company about a rental vehicle, if you have full coverage with roadside assistance.

Water in the fuel can do a number on injectors.

Well it looks like you guys were right. Mechanic said its likely the injectors. They won't know more until he gets into it. Bottom line is I'll be without my truck for a few days. I guess there's others ahead of me waiting for some work. I'm more upset that they won't give me loaner in the mean time.

I would not drive it. A tow to the dealer is much cheaper than a blown engine.

X2, if the injector is stuck open it could torch the piston.

FWIW I have never seen my truck smoke during a regen..
