Great thread, but it was old so I'm starting a new one. I have done alot of reasearch on this subject as well and have a couple points to add that I didn't see mentioned.
Filtering is obviously important but keep in mind, if you're using your own WMO, a simple but critical step would be to drain your oil into a VERY clean container. Your oil has been going through filters 1000s of times. It's not really THAT dirty when you drain it unless your one of those 'every 20k miles whether it needs it or not' oil changers. You could run it through a seperate filter system if it makes you feel better but I don't believe it's critical. Anything smaller that 10 micron is very likely overkill. 1/6 the width of a hair is very small plus it is still running through your fuel system filter. If you think thats scary, next time you need to drop your tank, look inside with a flashlight to see all the (very visible) chunks of crap in there. Thats scary, but it's in every one of our tanks. 1/6 hair size ain't so scary after that.
Point # 2, most cops I've met are not diesel truck experts. The only waste fuel oil you should even be kind of worried about is large doses of ATF, because it's red, just like offroad. Darker fuel can be explained off easily by saying you ad Bio-Jr to control bacteria growth in your tank. It's not very likely they would challenge you on it. And yes, bacteria does grow in diesel and left unchecked can get thick enough to clog filters. Big problem with boat diesels, google it.
Point # 3, from my research, it seems the biggest potential danger of running lots of WMO is not the particles, it's all of the chemicals and acids and such that your oil picks up as combustion by-products during it's 3000 mile life. I can't pluck the list from memory, but it is a list. If this has potential for damage, it seems it would be a long term problem like some acid that will react to a certain metal type causing a microscopic amout of damage but compounded over several years of running a high ratio, eventually causing enough to require overhaul/replacement.
I can't swear this would happen but the potential is clearly there.
and item # 4. This is one I just stumbled upon the other day and haven.t had a chance to check. There is a guy on ecomodder who states he makes something very similar to diesel fuel by putting 40 gallons of WMO in a barrel and adding 6 gallons of unleaded gas, mix it up let sit for one week. Apparently all the crap falls to the bottom. Draw out all but the last few inches and filter without disturbing the crap cloud at the bottom. Thats it.
I plan to do a test in a 5 gal bucket with 4 gallons WMO and .6 of gas and see what happens. Ya never know. He said it ends up being alot like diesel.
As far as my personal routine, so far I've been mixing about 60% 2-cycle 40% diesel kleen in 32 oz gatorade bottles and dump one in at every fill up. It's simple and easy to carry around until you need it and it's approx 1oz per gal of fuel which is the suggested ratio for pump/top end lube. Lack of a good reliable supply has so far prevented me from jumping on the WMO wagon, but I'm keeping my eyes open and plan to work it into my system in the future.
Well, my eys and fingers hurt after all of that so I hope someone finds it interesting.
