if i run say 1 to 4 ratio of used oil to diesel, it shouldn't hurt anything, as long as its filtered fairly well and dosen't have anything besides oil/tranny fluid in it right?? the reason i ask is because i added almost 4 gallons to my tank and saved myself 11 dollars in fuel cost, i can get clean used oil by the 5 gallon buckets all week long, it just smokes some more and with the LSD and ULSD fuel i think it would help with pump lubrication.

 

1:4 seems pretty high, but I sure could be wrong. That would be cool to use though, with prices of diesel so high these days.

 

actually more like 1 to 5, 4 gallons of oil to 20+ gallons of diesel. that probably gave me 50+ miles on this tank for free.

 

As long as mileage doesn't suffer.

 

What would be the best way to filter the used oil? I got MANY 5-gal buckets of used oil just sitting in my barn that Id love to get rid of in cost effective manner.

Will any used oil do? Cause all of what I got is out of our only gas vehicle and little ford 8n.

 

The Cummins oil burner recommendation was 5%, so that's a way high concentration you're talking about there. You're running the risk of prematurely wearing out the lift pump and clogging the fuel filter if you don't filter it really good. Here's my used oil filter. Uses a roll of toilet paper as the filter element and the used oil comes out the bottom clean as new, particulate-wise:

It's nothing more than about $20 worth of PVC, clamps, glue and scraps.

 

i am gonna build my own filter, something like that, if you do pour it straight into the tank, let the last couple inches stay in the bucket so you dont get any junk.

 

I was thinking of taking a long PVC pipe 18" or so and stuffing one end with 6-8 inches of toilet paper. I mean stuffing it real tight so that the oil takes several minutes to run through. Hows that sound?

 

It takes about three days to filter a gallon through mine. Slower is generally better for filtration purposes.

 

I just dump it in and let the fuel filter do it's job. As long as it starts and runs ok I see no problem with 4 to 1.

I just ran 3 gallons of my used stuff with no ill effects... brings my mileage to 28.4mpg that I pay for... I also just let the fuel filter do its thing. I would prob filter oil that was given to you, but be sure it is from a close friend so that you klnow there isn't any other oils that may be added into the bucket (i.e. gear oil, antifreeze and such). Anywa, happy burnin...Jake

 

this stuff is coming out of good trucks and tractors, nothing i really have to worry about, just regular 4,000 mile oil. it sure smokes alot more though, but i like that. once i get to florida i am gonna set up a tank with a hand pump and filter so i can make it cleaner and easier to empty into the truck.

 

I agree.

I know of several Ford/Internationals that are burning waste-oil 100% with no issues.

I would be hesitant to use old oil from anywhere but my own stuff, as they will dump brake-fluid, transmission fluid, anti-freeze, and tobacco-spit in with the used oil.

I pour mine through one of those paper paint filters, to get out any clumps of gunk.

Then, I scavenged the filter-holder from a MR COFFEE, and pour the oil through a coffee-filter, before pouring it in my tank.

It takes about two days for a gallon to go through a new coffee filter.

After a gallon, the filter will nearly stop flowing at all.

Does anyone know the "MICRON" rating for coffee filters ??

 

BK, ther reason your coffee filter runs slow is not because it is getting a low micron rating, it because it is CLOGGED. There no depth to a coffee filter. After the first few minutes the surface is covered with whatever it catches and it clogs.

 

all the guys i will be getting it from are my good friends, they keep the oil "clean" cause they use it for starting fires. transmission fluid really wouldnt hurt, its actually pretty high sulphur.
