Here is a question I've never found a convincing answer to:
A mate just sent me a message wanting to empty a heating oil tank he no longer uses.
Particularly at the moment, I've wondered if it's ok to burn in place of retail fuel.
I'm only running old-school diesel engines (Perkins 1000 Phaser is the most modern).
So - what is in 'diesel' that is missing from heating oil?
The various 'snake oil' additives seem to contain the detergents that are already added to diesel fuel, so perhaps this is one place they would actually be valuable?
