It might be OK since its NA, the ECU will react to the knock and retard the timing. Or you will break a ring land or spin a bearing pre-maturely, especially with those tight bearings for that thin expensive oil. The worst thing to do is switch back and fourth.

Would you run 87 in any other 11:1 engine? I wouldn't, and I wouldn't run 87 in the Scatty Pack (wish I had one).

Shoulda just bought the V6 Doc, then you could run spin tech oil and 87, but I know you wanted to look cool apimp
