Pure fuel oil would be nice. Actually there is no such thing as pure fuel oil.
There is water in diesel by the time you put it in your tank.
Fuel jobbers should put drop out in the fuel before it's loaded but this is still not 100%.
There is water in gas as well but much less of it.
I agree 5% is (might be) a bit high. Maybe I should have just said there is water in diesel.
Every time I check my bulk tanks
there is.. well, lets just call it a butt load of water in it.
Diesel has a few other "additives". However, water is not one of them.
Not an additive. Just no way to get it all out.
I do not know of any "aftermarket" additive that disperses water. To disperse water, it would mean the additive was hydrophobic.
About half of the products on the market do exactly that. What I mean by disperse is to break up water into small particles allowing them to pass through the filters and through the fuel system.
This can get rid of normal (normal meaning what's it most peoples diesel) amounts of water in your tank thereby reducing the possibility of growth.
The thing is the water is then in the fuel injection system. Running this water through can cause injector problems. However the other problem is when you are not running the engine
. The water can corrode the internal parts
of the fuel system. Pump, lines, etc.
Perhaps we should just call it an emulsifier instead of a dispersant.
Demulsifiers are used in the other types of diesel treatment to collect water in a separator. These types are best for the fuel system. Instead of dispersing (or lets just say break up into smaller particles) the water that has collected in your tank (for whatever reason we decide to name it) it causes the water to not e able to break up into small enough particles to get through your filter system.
The demulsifiers are the type most manufacturers recommend. emulsifiers which normally contain alcohol will void the warranty on most diesel fuel systems. despite this fact there are thousands of people that use it.
So you need to decide. Use a demulsifier and collect the water in a separator close to the tank preferably, or use an emulsifier and have fuel system problems.
Check with RACOR
and they will tell you which kind they recommend.
The filter system is designed to do a certain thing. Not much point in buying
something to defeat it.
