Keep or remove OMP....can't make up my mind...

I've been pre-mixing for the last year b/c my OMP stopped working. Pre-mixing is annoying. I'd rather have the OMP do it for me.

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.
