new to the WMO game - Diesel Forum - TheDieselStop.com

Here is how I do it.

WMO

I am going to run W85 when the weather breaks. I have WMO and filtration as well as de-watering. The guys at the benzworld forum seem really opposed to the WMO alternative to diesel and insist it will destroy the engine. Looking for feedback either way.

I think it really depends on how you use it. I also think different engines of the same make will respond differently to different blends, so it takes some time to find what blend your engine likes best.

I am really impressed with the systems people have, they all seem great!

Soon I'll be rebuilding a building I have (2100 sq ft) and it will include diesel fuel production.

Could be by filtering or by making biodiesel, or both.

I really like the idea of using the lab and the centrifuge because of a warning I found in the MB diesel books from the late 50s specifically a 180D owner's manual from 1957

In those days, they didn't have that many winter grade additives.

They said you could dilute diesel fuel with up to 10% regular gas, ROZ 93-95 octane level.

However, they said UNDER NO CONDITIONS use premium gas because it contained vanadium additives which were harmful to highly-accurate machined surfaces in the fuel injection pump.

So my question:

1. Do they still use vanadium in premium gas?

2. If they do are the machines surfaces of the pumps any better?

Does anyone know for sure?

Not sure, but regular is the standard because octane is the opposite of cetane. So the consensus is to not increase the octane by adding premium gas. Plus, adding premium gas increases the cost of the fuel, so it doesn't make sense. In addition, (this has already been stated) when cutting OIL, not diesel, with gas you can use more gas due to the higher lubricity of oil vs the current diesels available.

Any particular reason why you filter it? It's already been filtered by the oil system, and passes through two filters on the way to the pump.

The filters don't catch everything. Tiny particles will still be present, as will soot and general "gunk" -- you know, the reason you change the oil in the first place .

you can't believe how much small junk is in will that come out of a supposedly clean engine. If I run my centrifuge for 6 hours it has about a quarter inch layer around the inside of it.before I ran my centrifuge I was constantly changing a fuel filters.

So instead of neatly disposing of a cheap fuel filter, you run your centrifuge, and then do what with the sludge?

If the dirt is small enough to pass the fuel filter, is small enough to make it through the fuel system. I just don't get it.

Our county has a household hazardous waster collection once per month between April and November in which they combine it with other WMO then reprocessed into fuel for ships, and asphalt by an outside firm.

I recycle the sludge with my parts washing fluid. I dont have to change change filters as often. Without centrifuging, I had to change filters often. im sure its better for the enviroment to run the cleaner fuel too.

Sure, that makes sense. You burn high sulfur oil that contains 10% heavy petroleum fractions and you're an environmentalist. Let me give you a medal.

In my area, trash goes to a trash to energy plant, so filters go right out with the garbage.

I mixed two subjects here, but the BLUF is: oil filters don't filter past about 19 microns on a good day. You need more!

A Year ago, I did an extensive survey of oil filters in order to create a custom oil filtration system for a 1937 Citroen Traction Avant. In the course of that, I discovered that most oil filtration systems seem to operate at about 25 microns, with others going up to 19 microns.

I have seen the commercial fuel filters go as low as 10 microns and the folks in the WMO activity are looking at 2-5 microns.

If that's so, it might be time consuming for industrial mproduction purposes, but I'm betting that a small gravity-fed or lower-volume system could filter to 2-5 microns and still provide its user with what it needs.
.
Plus: I want to send a sample of my first batch to a lab, get a spectrophotometric analysis, that I can fram and hang on the wall!

It's in the link at the top of the page, but caterpillar uses 2micron absolute. That's 97% guaranteed. It's a mighty large filter, though and it's slowwwwwww. Anyway, just because particles will pass through a system does not mean they won't damage it. I think someone used the sandpaper analogy earlier... Maybe another thread. Anyway, the point is any abrasive material will do some extent of damage.

my first setup was a whole house water filter then two goldenrod water block filters and ended through a 10 5 and 1 micron filter bag, I literally did hundreds of gallons of w85 in my idi ford like that, then I decided to buy a centrifuge, I ran my filtered "clean" oil through that and got layer after layer of gunk, so now I filter and fuge for piece of mind.
