OP
Just to be clear, it is only my
opinion you can / should use a diesel additive formulated to "remove" water. You can read these forums until dead tired and still not reach a decision on what to do in this case.
Some will say yes and some will say no to additives:
- BMW says NO (well BMW says not to change your transmission fluid too

; and we know that spells death to your transmission)
- A well respected company makes a product that can be helpful here, by making the water soluble in diesel and allowing it to pass through and burn off. (since likely very little water was sprayed into the tank)
- Look up
About Us | Power Service and read about their products.
Some will say change the filter:
- Is that a guarantee to remove the water? Is it really all just sitting there in the filter?
Good Luck
Personally, I use the Power Service Diesel Fuel Supplement +Cetane Boost. I do this primarily to add lubricant to the diesel and the cetane advertised at all stations in my region is "minimum 40". This is a cold weather formulation that also prevents geling and icing of the fuel. There is a summer formulation also. In addition, based on my readings this afternoon, I intend to run some of their Clear Diesel quarterly to remove water (which is in ALL diesel fuel).
