Noticed a big change in how long my cedar pickets last after switching to a different post treatment

I used to get about 7 years before rot set in at the ground line on my standard pressure-treated pine posts. Last fall, I switched to using a copper naphthenate paste on the below-grade section before setting them. The difference in the wood's condition after just one wet season is night and day. Anyone else have a go-to method for extending post life?

Ever try that old trick with used motor oil? My grandpa swore by it.

What did he use it for?

My old truck's squeaky hinges finally shut up after a dab of that stuff.
