Getting Water In Wvo Any Ideas On How To Easly Get It Out.how About A Dewatering Filter Under The Hood Any Other Easy Ideas On How To Dewater Thanks.

Heat it up, let it settle.

If it has to be on board dewatering, I think a vacuum system is supposed to work, but seems like to much trouble.

There aren't any filters that simply filter water out.

Here is your solution;

If you have a West Marine nearby or other boating supply stores they should have it in stock.

You need to let your WVO settle for a good 4-5 days and only pump off the top- leave the bottom 4-5 " for settle room.

Starton Diesel Additive works, and you won't have to add a dewattering filter...

add 1/2 oz per fillup.

You do have a 12v facet fuel pump hooked up already? Don't ya?

A water seperator won't do it. You have to properly dewater BEFORE you fill 'er up.

2 options
1) Post and discuss this topic on the WVO Thread.
or
2) Drain out the grease and replace with diesel fuel

Well, as long as you're cranking an old MB I guess I can tolerate all you upstarts using the "wrong" kinds of fuel and cluttering up the forum with blather about the problems associated with the many failed engineering attempts to make it work or to improve it's reliability or maintainability.

Especially as long as it ain't mine or you don't contaminate a virgin, survivor diesel with the gunk and the Rube Goldberg contraptions needed to ruin (I meant run) 'em using the stuff.

The key is to enjoy them and drive em like they need to be driven...long, hard, fast, hot, and repeatedly!

Good luck and Motor on!

I heard that isopropyl alcohol will help remove the water quicker.

Do you have a drum with a hanging filter bag and a pump? if so...Settle for a few days in cubies. Pour off the top dry oil through the filter into the drum. let it settle in the drum for another day then pump it out. If you set your pick up on the pump high, any water that makes it into the drum will settle on the bottom and not be pumped out. My drum needs 7+ gallons of oil to reach the pump pick up. Also good is a drum with a drain on the bottom to drop off the water. Water and oil don't mix.. give them a little time and they will separate themselves. If in doubt do a pan test. add the filtered oil to a saute pan that is over 225f if it sizzles it is wet. I would be very skeptical of on board water removal. I want to get the fuel as close to perfect as possible before adding it to the tank, why knowingly add water to your gas tank???

Water seperator filters don't work very well with diesel and they work much worse with WVO. If you value your vehicle, you will properly de-water and filter your WVO before you put it in your car.

A proper conversion with properly de-watered and filtered WVO will make your engine last LONGER than running on diesel. A bad conversion will kill the engine.

By the way, I only draw off the top 10% of the oil in my settling drum.

Wow! I thought My system was thorough. You must have a very large drum. It would have to contain like 200 gallons for you to be able to fill up from the top 10%. Another consideration on the de-watering is obtaining your oil with less water. My source gives me the oil in the pot they drain the fryer into. since that oil was at 350f there is no water in it to begin with....

If WVO is milky, I just will not accept it. I tell my sources, NO WATER, they usually do good. They really don;t want to pay to have it removed with the tighter margins at restuarants blah blah blah,,, cluttering up forum,,,

Bama1 did you know Mr. Diesel designed the compression ignition engine with the intent of burning peanut oil? But Rockefeller came along and the rest is history, so please don't go blathering about the forum members that discuss their problems associated with the many failed engineering attempts to make it work,,, after all there are a considerable number of forum members that do burn WVO in their diesel,,, However, I do agree that this particular thread should be moved to the WVO thread because it's not really related to compression ignition and troubleshooting, or repair of aforementioned engines.
just my 2¢

Thank you for emphasizing the point.

Also, Mr. Diesel's engine patented in 1892 was designed to burn coal dust as a fuel and not peanut oil. Although he tried that years later...he must have had as much trouble with it back then as you folks do now.

No, my settling drum is only about 60 gallons but I introduce the used oil into the BOTTOM of the tank slowly thru a diffuser. If I put in 5 gallons a day, it takes over a week for the oil to get up to the outlet near the top of the drum where it gravity flows thru a 2 micron filter into my storage tank. The settling tank is heated very evenly and well insulated so there are no convection currents to disturb the settling.

The settling is so effective that I get about 2000 gallons thru the filter before I need to change it. The oil is so clean after the filtering and settling that I have NEVER had to replace the WVO filter in any of my vehicles.

By the way, even if you get oil directly from the fryer, if food has been cooked in it, there will be water in the oil.

The water in the food will flash into steam in the fryer. Some of the steam will bubble up thru the oil and go away but some of the steam bubbles will be so small that they won't float up and some of the steam will even be absorbed into the oil. Remember the hotter a liquid, the more water it will absorb. I heat my settling drum to about 120F. Hot enough to keep the fat melted (I want to burn the fat too) and low enough that the oil can't hold too much absorbed water.

I have been using this method of water removal for over 25 years even with solid animal shortening and hydrogenated oil with no problems.
