waste engine oil??
I read on another forum a week of two ago about running old merc diesels on 50/50 waste engine oil/diesel mix, with the oil filtered of course!
I gave it ago last week with a 617 n/a G and its runs very well!
any one else ever try this?
any liquid carbon based fluid with the right viscosity will burn in the diesels of old but the inland revenue will frown on that one unless its a plant based engine oil check this out http://www.swissinfo.ch/eng/multimedia/video/detail.html?sid=11013634&si...
Never heard of anyone burning waste oil in a car before, i wouldn't like the idea. Waste engine oil is very dirty stuff. We have a waste oil heater at work and you would not believe the amount of muck that comes out of it. It needs to be cleaned out about once every 2 weeks or so and the oil goes through 3 filters and a sediment trap before it even gets to the heater. No way would i let that stuff go through my injector pump. But I am going to give waste veg oil a go.
Unless i need to turn down the oil prehaeter a bit, i've it set to 85 degrees, Maybe the oil is to thin and its drawn too much in, but there isn't the least bit of smoke from it. I've read some forums saying that wvo is very acidic and not good long term, i'd imagine waste engine oil containing alot more bad stuff, filtered or not. How long have you been using the waste oil?
Im not expert on waste oil burners, but we used to have one in a workshop and It was forever needing cleaning out as you say, after it was serviced (pump turned down) we didnt need to look at it after that.
I think the main thing with waste engine oil is that it has been left to settle for a few months as a couple of the barrels I have the oil is actually very "clean" and very different to oil straight out of a sump, it wipes off your skin unlike oil straight out of a sump, but there is a heavy black sludge in the bottom of the drums that is like treacle!
Very interesting reading there. More research will have to be done.
We burn our waste oil as well to heat the shop. It takes two huge systems in our shop to heat the large area. It works really well for that, but it is a totally different machine than a Mercedes engine.
I too looked into this but after research and discussion realized that used engine oil is filled with to much garbage that it isn't worth it.
If I was going to burn oil in my diesel I would only use used transmission oil as it is a lot cleaner than all the gunk that builds up in used motor oil.

I think you need to look at your waste oil heater, the pump is turned up too far, or there somthing wrong with the ignition, its not burning the oil!
I'm filtering waste oil with a 100 micron sock filter, then 20, and then 1micron hydraulic oil filter from barrels that have been standing for over a year and theres little or no contamination after 200ltrs of oil,
ive started running my amazon landcruiser on it to and it runs fine!
