I recently read something about adding the used oil from your crankcase (20
quarts from my engine) to your diesel tanks to burn up, thus saving the
purchase of five gallons of fuel and eliminating the problem of disposal.

I would be diluting it into 320 gallons of fuel.

Is this common?

And how much would in cost in fuel filters? Maybe in an old Detroit Diesel.
But not in any new diesel with a high pressure pump.
