Will Deisel Kleen do damage?
 

I added diesel kleen to my 97 F350 PS, got about 10 miles down the road and now it is blowing dirty white smoke almost constantly....I could fog the whole neighborhood with it in 5 minutes it is so bad. There is no drop in performance but I am now afraid to drive it. Any thoughts? It almost looks like a car after you sea foam it only this doesn't stop blowing white grey dirty smoke and tons of it. It does not throw any codes, and passes all of the electrical but it does fail the contribution test on a few cylinders....would the next step be checking compression via the glow plugs and then assume I may have a stuck injector? or should I just drain out the diesel with the diesel kleen in it and start with fresh deisel and see what happens? I don't want to blow the thing up....

It's not the diesel kleen doing it

Bad news.....could it be a stuck injector?

So I am gonna drain the tank tomorrow and replace with fresh diesel and see if the issue stops. I am new to diesel but it seems to me that it should not be running great and doing this....my guess is that I have a stuck injector even though it passes the buzz test. I sure as hell don't want to hydrolock it....I am finding out that perhsps a 7.3 with only 140K on it may not have been such a good deal after all...

do you not have two tanks on yours? I run diesel clean fairly often, especially in the cold weather. Never had any trouble with it but i would try not to waste all of that diesel if you can help it. I cant imagine that diesel kleen would be the issue

I run diesel kleen and 2 stroke every fill up and havn't had problems at all, I wouldn't waste that fuel :c:

I even use DIESEL KLEEN on my 2008 6.4, & haven't had any problems

I have been running Diesel Klein since I got my truck and it has actually made the start, run, and mpg a lot better. It could be the Diesel Klein doing it's job and flushing out the system.

Can't see it being the diesel kleen.

I run Howes diesel treat and every few thousand Km a bottle of diesel charge from wynns that I started using once I watched a 6.0L pull in running like garbage, and pull out running fine after having a bottle of it dumped in and run through for an hour or so.

it's not the additive.

Have to agree with the others, I really doubt it's the diesel kleen. I think you're on the right track with the stuck injector. Even if the diesel kleen dislodged some gunk in the fuel system, it shouldn't have gotten past the fuel filter.
