We have been using raw (not boiled!) linseed oil mixed 50/50 with straight gum turpentine for 16 years. Works very nicely on oak, doug fir, cherry, poplar, hickory. Doesn't work well on rough sawn or hewn material.

It's also totally healable (repairable) after the subs (boneheads) have dinged, marred and smudged your timbers. Just re-sand and re-oil. Viola!
