I'm not comfortable with adding petrol to fuel for a diesel engine and I can't see it cleaning the combustion chambers.
And I believe using mineral oil as fuel falls foul of HMRC as it attracts fuel duty.
I can't see that used engine oil, unless well centrifuged would be good for the injector pump and the engine.
years back in series days in winter used to add 1 gallon petrol to 6 of diesel to stop it waxing up , never suffered any damage .
