Author Topic: Putting used engine oil in tank, Good Idea???? (Read 10972 times)

mtnbob · « **on:** June 14, 2008, 06:53:09 am »

Just wondering. I'm hearing about people who filter their used oil in a few large funnel filters and pour it into their tank. Stupid?? Not worth the hassle?? Anyone actually try it? Dangers?? :shock:

it should be filtered down to a few microns to be safe, but yea some guys run a 50% mix... i think that is a little bit high though.

I think it should only be used as a lubricity increaser if anything. However, I wouldn't run it in my car. There is a reason why we change that oil out

1 litre per tank tops IMO.

Spend some time browsing through the yee-hawl pickumup truck diesel forums. You will find that for every one guy who swears by it, there is another guy who runs from the idea.

What I have evolved to believe is that there is the potential for ash build-up in the engine. I get this from the above mentioned forums. How much?? Nothing is clear.
Check it out and get back to us on it. Take a scientific approach (ratios, etc.).
I am about to embark on the hydraulic fluid thing.
I will start out gingerly and see. I will be very frank with my view and knowledge gathered. The opportunity is knocking. I will keep my tools handy.

I'm still running it. Usually about 20-30% max, beyond that and that dang thing smells nasty.

Interested in the hyd oil option. Let us know how that goes Dakotakid.

as long as you filter it down to about 2 microns (racor sells these filters, or even CAT - but you should get a small lift pump to help push it through) there should be no problems other than filters that plug up a bit early.

with thicker fuel the injection timing will be delayed ever so slightly.

With thicker fuel the timing advance will advance extra much.

ok sounds like it might not be worth it :shock:
TY for the input

What makes ya say that?

Zuk:
Working out the final details on the acquisition. My source has the blessings/permission of his employer. Hope to get to it soon.
You would not believe the huge amount of hydraulic fluid that gets drained out of industrial equipment on a daily basis.
In my area, the recycler is GETTING PAID to haul it off.
The big equipment dealers who lease equipment often require their customers to change out this really expensive fluid long before it really needs to.
I am in a unique position where my source can hand select which oil to keep. And, he can run bottom sump tests on it to help determine which to keep. I am really looking forward to this.
I am hoping I might get one step closer to saying, "G.W., bite me!"

Hey Dakotakid, where could I find more information about running hydraulic fluid in a diesel vehicle. I just started working at a large hydraulic repair facility and I have access to a huge amount of hydraulic fluid. I am looking for info on the pros and cons, and any precautions that should be taken.
Cheers, Ryan

I have a Jungers space heater that I used to heat my garage with. It burns diesel fuel very nicely. I didn't feel like finding a source for fuel oil, and they seem to be the same stuff any way.

I tried mixing drain oil in with the diesel that I was burning in the stove, starting wit a 1/4 ratio.

Jeezus H kreist did that stove soot up. Big fluffy/crispy deposits.

I cleaned it out, and tried lower ratios, and the result took longer, but were the same. The 5hit just makes a butt load of fluffy/crispy soot. Its kind of greasy too, so its not burning completely.

If you run it in your engine, good luck....

COMPLETELY different combustion process there saurkrut.

jimfoo · « **Reply #14 on:** June 24, 2008, 06:32:51 am »

Bummer, as I probably have 40 gallons of drained oil. Although maybe in low ratios just every now and then it might not be too bad. I've used red diesel in my garage heater for a long time. No way I was paying $6/gallon for kerosene.
