Not worth damaging a diesel engine but why not filter it into your oil furnace. For a amount you of waste old you would add (for the average homeowner) and diluted furnace oil I think that would be a much better solution. Besides, right now home heating fuel is 10 cents more a liter than coloured so the payoff is better.
Edit: I guess this won't work if you use electric or propane, etc.
