Mixing used oil with fuel in Cummins diesels
I just read a directive from Cummins stating it was OK to mix your
used oil up to 5% in your fuel in their non-electronic engines. This is to dispose of the oil in an environmentally responsible fashion, sincrease lubricity, save fuel and it's a convenient way to get rid of it, especially while cruising. I have dual bypass oil filters, so I figure the stuff should be pretty clean and then the BIG dual Racors should filter out anything smaller that 2 microns. I analyze the oil at every change so if aything weird is in there i know about it, Why not? |

Do a bit of archive-looking in this and Seven Seas Crusing Association forums (ssca.org) and the sailnet morgan and other lists with me as the author. Way too many responses to try to duplicate here, but the scholarly response (ignoring the usual opinions of those who haven't tried it, and have no scientific background to fall back on) was that the acids won't be happy, the particulate/heavy stuff will coke out on your exhaust, and other reasons not to do it (marine being different than truckers and perhaps heavy power boaters). Other respondents cited friends and a couple of direct experiences which said they'd been happy, and one even provided several links to military directives to do just that. However, as none were sailboaters with minimal use and lower exhaust temps, my election was not to do it, as much as it's a nuisance to recycle the oil.

Skip,
Was the [assumed reliable] information you gathered with respect to big over-the-road diesels, that...it's OK to burn the spent oil ? If yes, in what proportions gas:spent-oil ?

I'm told that big fleet users do this all the time. The correct proportion is 20 gallons or more of diesel to 1 gallon of waste oil. Ideally the waste oil should be filtered before mixing but if you have a big set of Racors installed that is probably sufficient. Friends of ours have a long range cruiser which has an oil recyling system built in. Another possibility is using it for home heating oil. My old auto mechanic back in the northeast does that, just pours it into the tank. |

I think it would work just fine if it was filtered before adding. bob s/v Eolian Seattle |

Well, the tank was probably half full when I dumped in the results of an oil change - so say 1:150 bob s/v Eolian Seattle |

My old auto mechanic back in the northeast does that, just pours it into the tank. It works like a charm if you don't mind loading the neighbourhood with toxic waste products from the various heavy metals found in the engine oil additives. http://en.wikipedia.org/wiki/Lubricant "Burning the lubricant as fuel, typically to generate electricity, is also governed by regulations mainly on account of the relatively high level of additives present. Burning generates both airborne pollutants and ash rich in toxic materials, mainly heavy metal compounds. Thus lubricant burning takes place in specialized facilities that have incorporated special scrubbers to remove airborne pollutants and have access to landfill sites with permits to handle the toxic ash." I know that the use of engine oil for home heating is illegal in some parts of the world. Eric Stevens |
