What is the best WVO to use in SVO set up.

Had a talk with the local chipee and he said I can have as much cotton
seed oil as I want.
He pointed me in the direction of the waste drum, said its full .(looks like
a commercial companies waste unit)
He thinks they make biodiesel out of it, They just take it away.
He was quite pleased they took it away for free.
He said just bring a few empty cans and he will fill them up next time he
empties them which is every 3rd day.
He uses 50litres every 3 days.

So I thought my biggest problem would be to obtain WVO.

I tried not to show the big grin on my face.
Went straight to Bunnings and bought a few 25 litre containers as
recommended by our members $15.99 and two big 60 litre willow garbage
containers with lids for settling $9.98 (aussie made)

My only prob now is is cotton seed oil suitable for SVO setup???
Could not find much on cotton seed oil in the search feature.
Maybe some one can direct me to a good thread.
I know a lot of you use it in Bio diesel but what about SVO

Anyway pleased at this point and hope you don't disappoint me by
saying cotton seed no good.
Neil.
ps How do you spell chipee or chippee
