Oil Loss/Consumption/Pressure issue : Could it be Rear Main Seal?

[Hayes Myers]

I have no idea. Unfortunately.  Had oil change at safety. (4weeks ago?)
Noticed lower oil level and added 5/30 (dumbass) oil, 1 litre.  So seems to
be a mix in there now.  I bought some oil, 10/40 semi-synth LubroMoly ...but
haven't done a change.  Mayhaps that is necessary?  If it is the rms I'm
going to change the front and rear seals (have to do timing belt anyway).

What weight oil are you using?
