waste motor oil
« on: June 01, 2010, 10:30:35 PM »
Hello every one,
I thought i would post how i,am getting on.
I've been running my 6/1 for some time on a mix of 3.5 litres waste engine oil to 1.5 litres of petrol diesel waste fuel.
I've run other mix's and find petrol works well as a mixer but is expensive so petrol diesel waste fuel is free and my choice.
I find the injector tip gets carboned up and has to be cleaned, so i removed the change over valve and fitted a blanking plug which can be unscrewed and the injector tip clean.
Since i gave the engine a bit of attention its clocked up over 1200 hours on waste oil.
Definitely high maintenance.
Has any one else clocked up many hours on motor oil.

I'm using waste hydraulic oil from where I work and also have carbon buildup on the injector tip too. I just pull the injector and wipe off the carbon and she's good to go. My mix is 1 qt RUG to 2.25 gal WHO.

I run my 10/1 on wmo and so far I have also been lucky enough to also get some old diesel to mix in. I don't measure it just dump some in maybe 15 to 20 % diesel. I have run straight motor oil but you MUST start and shut down on straight diesel when I did that. Had problems one time and did not completely purge out the wmo and it was hell to get everything going again.
I have about 350 hours on my engine and most hours on wmo blends.

16/1 Metro  in the harness choking on WMO ash!!

10/1 OMEGA failed that nasty WMO ash ate it

By the way what is your cylinder index?
