Ive been reading alot about making w85 lately and decided to give it a try. Today I went and picked up 2 - 55 gal barels, one with an open top and one with a closed top. I also picked up a few whole house filters and all the fittings I thought I was gonna need. I just re-read the "wmo how to" thread and now see it says to use string wound filters. I was going to use the ones that go with the whole house filters but now Im wondering if those won't work? They look like there made of styrofoam or something.

Also let me know what you think of this plan for filtering. I was going to weld a 3/4" nipple near the bottom of the open drum. I would put a valve on the end, then a 30 micron filter, then a hose which would lead to the closed drum. The closed drum would be placed on its side, and I would atach a nipple and valve to the small hole, this would lead to a 5 micron filter and the pump with a hose atached. My plan is to dump the used oil into the large drum and add my 15% gas, then mix it up with a wooden paddle. I would then allow it to sit for a few days and then gravity drain it into the closed barrel. Then I could use the hose off the pump to go back into the top of the barrel and run the pump to circulate it for a while. After circulating for a while, I would take the hose off the top of the barrel and use it to pump into my truck. Does this sound good?

Here is a link to the filter cartridge I bought

OK so I did a little reading on these filters and it seems the one I have is a melt blown filter. I copied this off an article I found :

A melt blown filter cartridge is a "depth" type filter that is good for the removal of relatively uniform sized particles throughout the body of the filter, not just on the surface. Melt blown filter cartridges are particularly effective on well waters and normal city water.

A string wound cartridge is a "surface" type filter that is effective in removing diverse sized particles. It removes particles of its micron rating with excellent resistance to being "blinded" by larger particles. Because of the overlapping nature of the string windings, it has an effective surface area considerably larger than that of the melt blown filter. String wound filters are particularly applicable to surface waters from streams and rivers.

So from what I understand the melt blown filter will clog up quicker then the string wound if larger particles are passed through it. Is that right? Anyways I think I'll be ok to use the ones I have and next time I'll look for the string wound filters.

I use string wound. They last forever so I'm not sure if they really catch much or not. Check your filters to confirm that they have a sturdy core so as not to collapse under pressure.

For me, the string wounds are just there because I had them leftover from a previous experiment. My real filtration is done by three absolute rated truck spin-ons.

As taught by others; settling makes your primary filter(s) last longer, your primary filter(s) makes your final filter last longer, and your final filter makes your oem truck filter last longer. There was a time, while using string wounds and bag filters, that 200 miles on my truck filter was good. I could change it in as little as four minutes. Now, I change my fuel filter when I change my oil.

wow. Were you changing the filters so often because you just started running WMO, or do you think it was because of the poor setup? I hear that I'll have to change the filter a few times within the first 200 miles because the WMO cleans all the crud out of the tank. Seeing as the filters are like 30 bucks a piece if I have to change the filter a whole bunch of times because of a poor setup it sortof takes away from any savings from running WMO. If its just that I have to change it a few times in the first 200k then I can live with it. I'm also thinking maybe I should look at installing a cheap inline filter before the main fuel filter, but depending on the cost of setting that up it may just be cheaper to change the main a few times. I also don't want to run the risk of blocking to much fuel to the injector pump and ruining it.

WillNV; A full year before I started using WMO, I added a litre of NEW auto trans oil (ATF) to each of my fuel tanks at each fill from the D2 pumps. I also changed the stock fuel filter every 2-3 months. This, I reasoned, cleaned the tanks, fuel lines, lift pump, fuel bowl, etc, in a more controlled way before I went whole-hog into the WMO scene. Never did plug a filter, IIRC. You could try adding lesser amounts of processed WMO to your tanks and closely monitoring your filters. A pressure gauge on the fuel bowl can help. Check out posts regarding mixing WMO and D2 to see what the issues there could be. Cheers.

BTW you can save a lot on fuel filters as we found out when we bought 2 from the parts store and the cost was over $80.00. The guy we've been buying used truck oil off of got us fleetguard filters for $17.00. you might check them out. We returned the ones to O'Reilly asap.

willnv, the trick to making waste oil diesel fuel is to blend waste oil with gasoline at 15-20%, no paddle needed, just add the gas and it will become a uniform solution in about 1 minute. Then let it settle for about 1-3 days. Then, it is best to drain off the sludge at the bottom of the blending tank, which is usually about 10% of the blend, then filter down to 1-5 microns. I use one 20" 1-micron bag filter to filter my blend with.

I was putting dirty oil in my truck.
I was filtering with a rig that I made up from stuff I had on hand. There was no spin on filter. I took it out because it clogged too fast. :jester: Duh!

I was using dump truck oil from the quarry. Thickest, blackest stuff I've ever seen.
Almost everything I know now about this process came from DrMiller and rSr911. During the time I was clogging my truck filter I was reading but not heeding.

Good luck to you.
