With the rising fuel prices and always striving for better MPG/cheaper fuel I've been reading quite a bit on burning WMO. I decided that properly filtered, I saw no problem mixing it with my diesel in the tank. Of course doing this inexpensively was also very important........

So for all interested in WMO filtering ideas it's basically a 2 gallon pressure pot (like used for painting/ industrial liquid distribution) set up to run through a 6 micron fuel filter. I just fill 'er up hook it up to my air compressor and start filling containers

Of course all DIY projects involve something free, in this case it was my pressure pot. All in all with the filter base, filter, hose, and fittings I spent about $60 which I should make back in about 3-1/2 fill-ups running about a 12% WMO to diesel mix.

Good job. That looks like it should work great. Looks like that would be an expensive setup if one was to pay retail.

What is anyone using to make sure there is no metal in the oil before you pour it in your tank? it may not matter as much on a 12V but I would think the metal would play heck on a HPCR engine.

the 6 micron fuel filter that is on the front of the pressure pot.

It would be nice to filter it even finer than that. I'd love to rig up a Frantz setup on my WMO filter.

How small will that filter it? I could have also chose 2 micron filter, but im already filtering smaller than the stock truck fuel filter (10 micron).

I used an old cotton t-shirt...I wonder how many microns that is????

DBLR

What about any metal bits that are smaller then 6 micron that could still be in the oil, how do you get it out?

Clunk

You can get filter bags as fine as 1/2 micron on eBay.
Mix 50% fuel/50% WMO for timely filtering.

Centrifuges are capable of sub-micron filtration and are gaining popularity in WVO filtering because there is no maintenance costs like there are with buying filters. Several types have been mentioned on these forums somewhere.

This alternative fuel thing is picking up since fuel prices are going thru the roof, in about 1-2 yrs. we all will know a lot more about what works and what dont. I was in the diesel engine rebuilding business for 30 yrs, and long before all this BS started, you still had pumps, injectors going bad! in engines. ULSD doesnt seem like a magic bullet, on saving the world from the evils of man ethier! Ron

The Frantz filter uses toilet paper as the filter media. I know it sounds cheesy, but it is known to filter down to sub-micron particles, and it seems to be known and respected on these forums. It's been around awhile. Read about it:

then its also getting by the trucks fuel filter in the #2 from the station when I fill up. and even worse not just metal bits but Si particles.......... I dont believe im subjecting my fuel system/engine to anymore harm than it already is.

The big difference is that store-bought fuel hasn't been subjected to an environment where its sole purpose was to absorb small metal particles.
