So I just got started with my oil change, I haven't driven much since May 9th. when I started draining it just didn't shoot out it was just already no compression and I noticed while draining in the light there was a hint of red in there..is that a sign of a bigger issue? I drove my car the other day it was great! Just wanting to make sure, another thing to note is near the end it looked like normal used oil again.
