Yeah, I really hear you on that.
1) We burn petroleum products to heat our home / domestic hot water and it costs around $3.50 / gallon.
2) We have buckets of petroleum products that we have to go somewhere to actually get ride of.
3) If A=B, and B=C, what can we say about A and C? How long can it be before one wonders if pouring just a [bit, tad, scoosh] of that waste petroluem product into the tank that we have to pay to fill?
Bad idea though 'cause the oil contains fines that really should not go through the oil burner and it is too thick (even well diluted) to push much of it through the filters in the system. And really, if you are going to use little enough of the pit oil to not harm the system, how much can it be worth in real dollars? But I do sympathize and have often considered the same thing.
Now I once heard of a guy who used to start wood fires in a wood burning stove with pit oil. Seems this fellow poured a [tad, bit, dribble, spot, scooche] directly onto the wood pile before setting the whole mess alight. It seemed to work OK but you could hear the oil boiling and finally sizzling really quite loudly once it was engulfed. The smoke was not really bad either. But that fellow went over to a woodstove that uses a catalyst and those durned things just cost too much to plate them with tin from the pit oil :-(

Anyone doing this? I have a 275 gal tank and was wondering if I can add a few gallons of filtered waste auto oil without damaging anything. I've seen 100% waste oil mixed with a little acetone used in a home burner without any special tuning to the unit. I don't want to do that. Just want to get some use from my waste oil instead of paying to get rid of it.
