<pre>Be wary of using carbon dioxide. I heard at a workshop in Mildura in march this
year that CO2 is absorbed into the oil, creating a vacuum which can cause the
tank to collapse. I don't know the chemistry of this, but it would be worthwhile
to research further before putting CO2 in your oil tanks.

I am an Olive Grower and Processor in North Canterbury, NZ and we were advised
that we could use a blanket of Carbon Dioxide over our oil when it is in the
tanks after pressing and before bottling. It is considerably cheaper than
Nitrogen but is it as suitable? I understand it is not such as an inert gas as
Nitrogen so will it taint our oil? I would be grateful for advise. Helen Clausen
