Best treatment for an exterior Oak door?

[Finwoodhill]

Have just fitted an untreated Oak front door set, so don't want to leave it too long before treating. Undecided what is the best thing to use on it. I don't want It to be stained, just protected by something that will perhaps bring out the grain a bit and protect (but which won't need re-treating every five minutes). It will be exposed to the elements (ie, no porch).
So far suggestions include Danish Oil, Linseed Oil, Liberon Finishing Oil, Sikkens Cetol Filter 7 - it will be an expensive mistake if we get it wrong (have read numerous scare stories of Oak blackening if not treated correctly) so any advise appreciated!

The traditional treatment for exterior (and interior ) oak has always been linseed oil. The first coats should be diluted with turpentine 50/50 to enable maximum penetration. All oak, treated or not, will darken in time.

But some companies now make a version of Danish oil .. which I use ..with a few additives to harden and weatherproof.

Just Googled the Fiddes product (which I've never heard of before) and it does seem to tick all the boxes. Linseed may be the better long term solution though!!

If you varnish or coat oak .. and water later gets underneath .. and you don't correct it ...it will go black.
Spend proper time on thje end-grain .. and make sure end-grain cannot draw up water.

If you use a varnish of some sort .. like Cetol .. use a pigment first. You need to cut down UV. Otherwise it will peel PDQ.

Agree with all the others have said, Fin.......... remember, joinery oak doesn't like water. Believe it or not, it stains.......... and goes black.
In past jobs I've used Sikkens and Danish (not together of course.) Sikkens and similar last longer. Oil needs to be refreshed more often. I must admit that all the oils do look more "natural"........ as long as you're prepared for the extra upkeep.
