Jd,  I don't know what the environmental impact rules are where you are but they tend to be fairly stiff here.  There was a time that folks painted or soaked fence boards in Diesel, automatic xmissin fluid, or burned motor oil. It worked after a fashion but is frowned on today.  Long ago pine was charred in a fire before being place in the ground to keep rot and insects away.  I don't know how good it worked but it may be worth a try.  

The general rule is that coatings don't do a lot to protect wood that is on or in the ground.

Build yourself a good bed of coals and roll the posts around on the coals to char the wood real well.   I am not saying to burn the wood, but simply char, well done.   I would also encourage that the wood be heart and not sap wood.  I have Western White Oak posts planted in the ground and prepared as I suggested, that have been good and sturdy for at least forty years.   These posts were split by using a blasting wedge and powder.    Not a one was sawn.
