So, I changed the oil in my car the cold start issue appears to have gone away.

I had Royal Purple 5W-30 and a Royal Purple extended filter installed, with about 8K miles on it (a little over due, I know..)

Could dirty oil really be the cause of my cold start issues? Is it worth sending my oil in for analysis?
