I try to squeeze every drop of oil that I can from my oil changes.After filtering all I can from the paper bags, I place them in a 5 gal bucket and cover with water. After a couple of months,there is about an inch of oil on top of each bucket. I scoop this out and funnel into a 5 gal water jug with a plastic hose inserted in the bottom of the jug. The water in the bottom can be drained out leaving the oil. Got about a gallon and a half this way. Aint a lot,but every little bit helps.I would have tossed ths before. I dislike having to buy oil. Guess I got to much time on my hands. snuffy

That is very cool. Don't think I have the time but it is still a great idea to keep in the back of my mind if I ever get the time to do more! Fran

Thanks Snuffy! I just drained and cleaned my 12" drop saw again today and now have two batches of drainings to rescue. Since both batches have rock snot, water and oil mixed all mixed up together, I was looking on here tonite to see if I could find some info for separating the oil so I could reuse it. This process looks like it might work great for me. Not sure exactly how to set up the paper sack filtering system yet, specifically for my knowledge level. But after I get the sediment or sludge or rock snot or whatever the proper term is for the solid stuff, out of the liquid, I think your process will work great for me as well. I am still a hopeless amateur (IMHO) compared to most of the members I see here but I sure do learn a lot from this site. You all are just great.

I had an old rockhound tell me to mix water into the oil in a container that can be placed into the freezer. Let the water and oil seperate and the crud settle then freeze. He said the oil will be on top of the frozen water and crud and can be poured off and you get back more clean oil than any other method used to filter.

That sounds like it could work good,make good use of all the plastic gallon milk jugs sitting around. I'll have to try that too.

Don't use plastic milk jugs to store petroleum oils for long periods of time (like a year or more) as they will deteriorate from the oil. I had some (8) for a little over a year and everything looked great till I bumped one of them and it shattered! Now I keep all oil in a containment tub (for mixing concrete) with the jugs inside it.

Have to rethink this,didnt want anyone to lose their oil,the silicon Iput around the plastic hose in the bottom of the jug didnt stand up to the oil,started leaking.

You can just leave the sludge in a closed bucket. Oil will keep rising. I've never mixed oil and water so can't comment on that. I can hear my wife now if I suggested putting jugs of dirty saw sludge in the freezer though.

I seem to have pretty good luck with just the double brown bag filtering. Got to admit I'm too lazy to do much more. I used to let it settle in jugs and decant off the oil but the filter method seems easier and I recover a couple of pints of oil from a change of the new 10" saw....Mel

I have seen the water trick used. He would mix the oil in 5 gal buckets 50/50 with water. Let them set until the rock bits settled into the water. Then freeze the buckets and pour the oil back into his saw. It seemed like a lot of trouble to me. I prefer the paper bag method.
