Hello!

I know that a few people out there are pouring used engine oil into their fuel tanks as a method of disposal.

How, exactly, are you re-filtering the oil before putting it in the fuel tank?

Thanks!

Yeah I'd like to know too. I've got a few gallons sitting in my garage and I'd like to find out a safe way to use it if I can before I end up taking it to the next hazardous waste collection in 2 weeks.

It says "Diesel fuel ONLY" on the tank for a reason...

That said, I burned out 2 glowplugs on the first time I tried this with clean oil. I would presume by the oil coating the GP when injected cold.

No offense intended, but I've seen the debates on this subject in other threads, and would prefer to not turn this thread into a debate on whether or not the practice should be done or not.

Thanks

A guy on the mbz.org diesel list uses an aftermarket remote oil filter mount w/filter, as well as an electric pump to pre(post?)filter the waste oil. I've been considering doing this with both crankcase oil and ATF, but in small amounts per tank.

Ive heard that mixing it with Waste Vegetable Oil seems to make the soot drop out. I have also heard that the toilet paper filters are very good for removing soot.

Stilll though I would not use it as fuel. The added chemicals in the crankcase oil that will be emmited out the exhaust are IMHO most likely to be horribly poor for the environment. The FREE oil drop offs for recycling are "suposedly" better way to go. Free recycling can be found at any Advance Auto or Autozone, Pep Boys too I think. Dont want to debate here like mentioned above but feel free to throw me a link to show me if I've formed any false opinions.

Read the aforementioned thread. R Leo explains where most of that 'recycled' oil ends up. It comes down to choosing your poison...

I use a home heating oil filter. These are 20micron felt filters inside the cannister. You can rig it up to an old cofee can, with the can opening an inch or so above the bottom of the can so the can catches the big stuff. It takes a few days to gravity drain (set it up so sunlight hits the can), and I stop when the oil is above the opening so I know I'm not putting any water into the filter. 6qt oil change means 5qt I can burn in the car or the shop heater. If in the car then 1qt oil per 100 gal diesel means a dollop of old oil per half tank of fuel and a logbook entry. I also pull the car's fuel tank drain every few years to get the gunk out.

I filter mine using the Knecht filter that's inside the canister bolted on the side of the engine. I figure that oil's been filtered well enough to be used on the main bearings in the engine so it should be filtered well enough to go through the IP.

My biggest concern are the particles that still might be left in the oil even after filtering it. I've never filtered it to try using it my tank but I would imagine that there may still be acids or other impurities that would be bad for the IP. From what I understand, the IP is assembled to higher tolerances than the engine itself. I rather not risk my IP for the sake of saving a few $'s. I want my car to last as long as possible.
My used oil went to the recycler today.

Your fuel filter would handle anything that should not go to IP, but it will be working over time to filter that oil. I would doubt that the OEM oil filter is less then 20 micron, and anything in the 5 to 10 micron size are the real abbrasives in IP and injectors. Before you pour it in make sure it's filtered to 5 - 10 micron or carry a spare fuel fiter in your travels.
