   No, in general it will have little or no effect.

   When you say "danish oil" what do you mean?  Lots of different finishes are called "danish oil".

   Thanks for the fast response - I am using clear Watco danish oil.

   What is the item you are finishing?  Watco is not a very protective finish.  It has little water resistance and little abrasion resistance. 

   You can mix up your own oil/varnish mixture and do better and be less expensive.  Mix equal parts of your favorite poly or non-poly varnish, boiled linseed oil and mineral spirits.  Apply it heavily, let it set for 15-20 minutes and then wipe it dry.  Let is dry overnight and do it again.  Finally let the whole thing dry for 48 hours.

   This mixture is more protective than Watco.

   Fir finishing

   Again, thanks for the advice- the project is a surround built around a gas fireplace that opens to both sides. The surface that needs the most protection is the top because people automatically tend to put things on it - including drinks. The colour is very important because the other woodwork in the home is aged fir that has developed a deep reddish tone. Will your recipe affect the aging process?

   Penetrating oil might make fir blotchy

   I've had problems with blotchy natual V G fir using penetrating oil finish.

   In my last house I built fir cabinets, had fir doors and trim. I coated it all with clear Benite then shot it all with clear semi gloss lacquer. That beautiful burgundy patina came through  nicely after a couple of years. I really liked the fir woodwrok in that house.

   The natural oils or pitch in the fir lumber causes it to absorb the penetrating finishes unevenly.

   I would definately do some test pieces first.
