Wood Preservative?
 

I am looking at using timber sleepers as borders for raised vegie garden
beds and pallets for a compost pile.
A friend told me that a combination of old engine oil and kerosene works
pretty well.
Can anyone tell me:
1) Is it true - will this work, and
2) What proportions of each do I use in the mix?

Obviously this would be appealling as a relatively cheap and 'green' option.
