Ken I'm not sure but I tried it once & changed 4 filters in under 100 miles & all were filled with some sort of goo that just screwed up the works so now I avoid it. I don't know if this test is correct but what I do is pour a little in a pan & light it with a Bic if it won't light I won't run it.

 

Biodiesel won't light off in the test you just described.

 

As long as WMO does I'm happy & this way I avoid those liquids that only claim to burn though I will admit that gear oil in the open is heap stinky.

 

I been storing up gallons of WMO is hopes of running it in my truck. I just haven't come up with a cheap and non-messy way to filter it. I don't want to buy a big dollar filter set-up - that would defeat the purpose of running free WMO.

I plan to mix it with diesel at about a gallon per fillup. Just enough to get rid of my own oil change leftovers (the Ram and three cars).

I here about people filtering with 1 micron bag filters. That seems messy and overkill. The stock fuel filter is only 15 microns. The filter at the gas station is 30 microns.

 

My first batch was done with bags but I gave it up as far too time consuming. On the other hand if I was only adding a gal per tank I'd do it at the time I changed the oil & not mess with filtering at all unless you are not running a oil filter. Something to consider is a gallon 4-5 times a year worth messing with ?

 

True, but the gas station isn't dispensing fuel that is heavily laden with soot particles (carbon; tiny little jagged, hard particles hoping to feast on your bearing surfaces, cam lobes, rocker tips, etc.). Just get a 5-gal bucket, put a hardware cloth barrier @2' off the bottom, hang a large bag filter inside the bucket, drill a hole in the bottom, hang that bucket over another bucket and pour in your WMO. Tomorrow, dump the contents of the bottom bucket into your fuel tank.

 

i have some small auto paint filters that i was told are more fine than 2 micron, i know it would be messy, but would that work? i got them for free and have about three gallons of oil id like to use or get rid of. does the oil ever come clean? i ran a little through and it was still dark, does it have to be honey colored before you use it in the fuel tank?

 

I would filter any used motor oil due to the possibility of metal in it from the bearings. Well i'd filter any thing used. High concentrations of used motor oil will probably bring your egt up to toasty. Don't get me wrong i've run it in big trucks at 10% and the egt came up quite abit but it ran very good.

 

those auto paint filters sound like they would work fine. The oil will never lose that inky black color no matter what you do to it. As long as it is filtered down to as low a micron rating as you and your engine are comfortable with, run it.

 

Guys I'm running my first batch of WMO and trying out the percentage ratio. I'm filtering through old/used jeans that are cut in half and stretched over a 5 gallon bucket.

Not sure of the micron rating denim gives, but I can dump a gallon into it and it will take 4+ hours to filter through. I filter it twice and it does seem a little cleaner.

Any advise, is denim jeans good enough for filtering?

 

my setup is 55gal plastic drum (free) with a hole cut in top to fit a 5/1um sock filter from McMaster Carr ($17). Then a northern tool 12v Diesel pump with hose & gas pump handle($100) with GoldenRod 5um water separator ($15). Then to the tank.

I run that mixture of 50/50 with recommend PS gray and about 5% RUG which seems to work good in the '05 CR. I've run into a few time when mixed with WVO that it started coking the injectors a little where I had to run staight #2 to clean them up with heavy dose of injector cleaner.

 

Honestly, no. For an older CTD it might be fine, but for a common rail, you need to filter it down to the level where it wont have any particles larger than what Bosch specifies is minimum requirements for the CP3 and injectors ( somewhere around 4 microns). If I were you, I'd invest in a set-up that would provide sub-micron filtration or at least 1 micron just to be on the same side. Tesla 440's setup sounds pretty ideal. Personally, I use a centrifuge to get below 1 micron filtration.

 

The reports I've found have listed blue jeans in the 5 micron range. The problem I'm quite aware of is that is "ideal" and worn jeans and different brands will vary the filtration rating. Generally though, I think it's around the 10 micron rating pretty conservatively.

 

Anyone running the toilet paper type filtration? Supposedly it's sub-micron and replacement filters would be cheap.

If it were used in a gravity type system(as opposed to the usual pressure system), would it still allow oil to flow through the filter at a reasonable rate?

I've been considering storing my used WMO in a plastic 55 gal drum., so if a reasonable cost and filtration method could be utilized, I may set some form of filtering system for it.

Thanks in advance!

 

what is prescribed mixture .?

ok I have a 35 gallon tank how much do I put in if empty or close to empty
or say 1/2 tank .wmo or 2 stroke oil or what ever I got to dump in there ???
