    Trying to figure out what the life expectancy of pre treated deal fence posts. I think they claim 20 years? I assume driving them straight into the ground will reduce that?

    I think you'd be doing very well to get 20 years out of any timber posts unless they are treated like ESB poles...
    I had pressure treated posts (probably just tanalith e treated) put in about 8 years ago and some of them are starting to go rotten, strangely enough at the top of the post rather than under the ground.

    With any luck I won't still be living here in 8 years so that should do fine.

    8 Years.... pretty poor quality. I have post and rail that I put in in 1992 and it's still in good condition.
    I reckon, nowadays, most of what is sold as pressure treated is only dipped, so about 10 years is probably about right.
