HOW MUCH WATER IN FUEL IS OK?

Equipment manufacturers specify that ZERO free water must reach the engine.

Zero water is not realistic. All diesel contains some percentage of water. The most important thing is to keep the water below its saturation point so that it stays dissolved rather than entering your equipment as free water.

Saturation points vary from roughly 50 ppm to 1800 ppm based on temperature and on the petro- diesel/biodiesel ratio. When water content reaches the saturation point, the excess water will fall out as free water. Your diesel may hold 90 ppm dissolved water when warm, but only 60 ppm when it cools down due to colder weather. The 30 ppm difference falls out as free water and settles to the bottom of the tank.

Knowing the water content is important and getting rid of it even more so. (To test fuel see our Fuel Products Page)

Here is how you remove 99.5% of the water:
