1. Emulsifiers / Dispersants (“Water Removers”)

These break water into microscopic droplets and suspend them in the fuel. The water then passes through the system and is burned off as vapor.

Pros: Good for small amounts of water, prevents icing, avoids visible free water.

Cons: Doesn’t eliminate water—just sends it to the engine. Too much can cause wear or corrosion. Not ideal for modern high‑pressure systems.

2. Demulsifiers (Preferred for Storage Tanks)

These cause water droplets to combine and settle at the bottom as free water.

Pros: Enables true removal via drains, separators, or polishing. Reduces corrosion and microbial growth.

Cons: Requires a way to physically remove the separated water.

Key Points

•             No additive destroys or converts water; claims otherwise are marketing.

•             Best practice: Use demulsifiers + mechanical removal (drains, separators, polishing).

•             For stored diesel: choose demulsifiers and remove water regularly; avoid strong emulsifiers in bulk tanks without drainage

The problems is with formulation physics. Some desired end results will require different treat rates to do what they claim. Changing the cetane and lowering the fuel gel point can be done but, not with the same additive at the same treat rate.

The more specific the product claims, the better chance it’s going to do what it advertises. The more claims made is equal to the number of one time users. A 5-in-1 additives may have 1- in-5 customers using it for a second time. Buy a multi function additive and tell us how many time you have made the second purchase.

Define your problem and buy the product that address that problem…not 5 others.

All that being said, if you have tanks sludge/algae/ fuel bugs in your stored fuel tanks and are clogging filters, this product is the answer.

Do not buy a biocide until after the tank is clean. A biocide is NOT a tank cleaners.

Here is a before and after treatment photo of tank sludge.
