I don't mind adding some if I go to the track but I don't like using it on every fill-up.

The FD's OMP does a really good job and oil is injected at a variable rate - injects more oil as RPM and boost increases - which is more efficient. If you are pre-mixing on a 1 oz per 1 gallon basis, its too much for low RPM, off boost usage. However, that 1:1 ratio works OK for most WOT situations.

I know my plugs are dirtier since my OMP failed and I started pre-mixing.

Overall, very annoying but I don't have time or patience to replace the OMP.

What oil are you using as your pre-mix?
