heating oil

Is it possible to use bio diesel in a home fuel oil furnace instead of heating fuel.

can used veg oil be poured straight in along with number 2 oil or does it have to be processed to bio.

The only answer is maybe. There have been some issues with gaskets and other seals reacting unfavorably to bio fuels and this is probably reason enough not to take a chance UNLESS your fuel supplier is going to cover any service required as a result of bio fuel problems.

As for just dumping waste vegatable oil in your tank...don't do it! More likely as not it will sit on the bottom of the tank, absorb moisture, go rancid and probably gel along with supporting microbial growth. You would at the very least end up with plugged filters and probably much worse problems.

I don't suggest concentration higher than 5% bio. Even at this concentration, gaskets & seals in the fuel system can be a problem.
