Sean, I use the Bunnings bags and then settling for a number of reasons

1) I do not clean the bunnings bags out, i use once and throw away ($1 cost for about 200 litres of oil is good value to me)

2) I do not have to mess around with the slow draining of all the fats at the bottom of the barrel

3) I regularaly drain off about 20 litres from the bottom of my upflow settling tank that gets used in my burner, so i prefer this to be cleaner (relatively)

4) From the upflow it gravity feeds through 5 micron bags and then gravity feeds through 1 micron bags.

5) Finally runs down into a 1000litre IBC for settling and mist washing (about 200 litres of washing for every 800 litres of oil) (We have 20,000 litres of water tanks so water waste is not an issue.

When i am in full swing with two cars, diesel gen and oil burner going we will be using 300litres week in WInter, so in the process of stockpiling now
