Metals and Dirt in oil

I've been running WMO for 10 years in a number of engines. The only thing I have noticed when using filters only was a build up in the fuel system (inside the filter housing and fuel lines) similar to the carbon on the bottom of a piston head after a few hundred hours. You can see the original filter system on the beige tank. I went to centrifuging the oil and have built this system, over several years. No need to use magnets. All the goop comes out. No more build up.


Here is a PDF of the process:

Indeed a really cool setup!! I don't have that much space so my setup is smaller and simpler though still employing a 120 gph centrifuge. I will get some pics up shortly. I've only been blending w85 for about 7 months- learned a lot( started by doing mountains of online research and talking to a feel really helpful folks out there. I have learned a lot of little things and plan on sharing in the next few weeks what I have learned. I test every batch with a hydrometer and a water tester. I still have a few upgrades that I wan to make to my system as I'm sure it's an ongoing upgrade process. Thus far I have processesed a little over a thousand gallons that run in a 5.9/ a Vw turbo/ m-11 powered coach. All w/no issues as of the moment outside( outside of the typical 1st filter change).

My current project is a new transfer pump as my starter pump isn't keeping up w/ current demands. Hoping to have it going this weekend as I have about 400 gallons of hho and 275 gallons of oil to retrieve.

I've seen alot of sbc pumps being built and wonder why I have t seen any bbc pics. My project consists of a new bbc hi volume pump and a new (free) 1/2 or 3/4 hp electric motor. Ill prob use the 3/4 since its free. Hoping to yield 10-15 gpm w/this setup. Anyone else tried a bbc

How are you testing for water?? Good on you for doing that.

Stupid question but what is a bbc??

For water you can use a sandy brae water tester! Tester is cool though a really simple method (if you heat your oil, I only heat what is nessecary) a small mirror above the tank bung will fog if its still evap'g water from the drum

BBC. Is a Big Block Chevy oil pump

There is never a stupid question! Most of us got to the point we are by Asking someone else.

Hold those HHO horses...

. I'm also a big fan of free or cheap home heating oil when I can find it. I've run about 800 gallons of that stuff and it's just like diesel.

Just to let you know...home heating oil IS diesel fuel. Unless you get lucky and score dyed ULSD then its technically illegal to use on the road as it has a higher sulfur content and will more than likely raise your sulfur content out of spec and legal limits.

If it (the home heating oil) is dyed then you'd better not be caught with it in your tank or there will be a hefty fine headed your way. The fuel is dyed to show it is for off-road use only.

WMO is for off road use only due to the lack of taxes on it. Better not be caught with it.

There are exemptions for home made fuels. Think about all the guys running home brew biodiesel and WVO. I read through them when I had a good WMO source. Of course, that was a couple years ago.

Legalities

As most have realized, in most states bio/WMO/blended fuel of any sort- depending on your particular states view (as some have a gallon exemption/ while others have actual type exemptions) is illegal unless you pay all aplicable road tax on it! Then again it's probably illegal to break wind in a state somewhere?

So I am very new to "black diesel" and doing my homework... Man you guys/gals on this forum are sharp!
My question is can you cut the WMO with JetA (aviation fuel)?
I plan to try the 85/15 mix... Also, my truck is an 05 powerstroke. Any specific issues with this 6.0 that I should be aware of? Thanks for all the great info.

Jet A is very similar to kerosene - a lot of people have used that as their mixing agent.

I guessing that your thought of using jetA could only be the result of a cheap source. When blending WMO with other "fuels" the 85/15 ratio was originally for using RUG (regular unleaded gas). I think it is generally preferable to use ethanol free RUG. Other fuels like K1, jetA or even D2, require a bit of a different ratio.
A few of the ways to determine a proper blend are to use the properties of diesel and make a blended fuel that approximates those, namely viscosity and specific gravity. You can use a zahn cup to measure viscosity (or any small cup with a small drain tube that drains a specific quantity of liquid in a certain length of time). As an example: you dip the cup in the fluid to fill it, lift it out and measure the time it takes to drain out, say 15 secs.
Or some instrument like a battery hydrometer can be used to measure specific gravity. There are of course other more technical properties of a fuel like cetane rating, volatility, and flame propagation, but a usable blend is attainable by the simpler methods.
W85/80 is a pretty trouble free fuel requiring little to no special changes in any mechanically injected engine. I've got ~6k miles on my '93 7.3 IDI running W80-85 (RUG blend) 99% of the time.
As far as your 6.0 goes I can only guess, but at the least you'd have to have a tuner chip with the proper tune for W85, there are also issues on some diesel engines regarding optical sensors that don't like fuel it can't see thru like any WMO blend.

So I havent posted in awhile- summers are crazy busy! as for the new guy- Im not to framiliar w/jetA but the 85/15 mix is definetily a rug mix. I have pretty much swt'd to non-ethanol rug as when using the standard ethanol unleaded gas i was noticing alot of condensate in the filler neck on my m-11 powered motorhome. Though like alot of electronic injected diesels it has a plate heater and returns heated fuel to the tank. after swting to non-E rug little to no condensate. took almost 600 gallons between tank and trailer to power us to Alaska and back this summer. Sure beat paying 6+ a gallon in Canada.

I have a question. Im really excited about trying a wmo rug mixture in my 99psd. I was planning a 2 tank system, one for settling and mixing, one for filtering. Plan on a 10 micron and 5 micron screw on fuel filter.

How do you know when to change filters? how many gallons will they filter?

Any help is ppreciated

Wow! This thread sure has grown. Question came up about WMO on the IDI Drivers group on Facebook. I haven't posted here in forever. Still have my truck but not driving it much these days. Only thing new for me is I'm not using RUG anymore as I'm suspicious that either the RUG or the ethanol in it eats away at the insulation around the IP solenoid and kills it. I got rid of the upflow processor as well. It really worked well for WVO but not so much for WMO. Boiling or avoiding water altogether works best for WMO. Anyway thought I'd drop by and say hi and give you all an update!

Welcome back, Chris! Hope things are going well. Are you still machining? A few of the new guys might be interested in your SBC oil pump plates.
