Hey everyone, I just had a question that I've been pondering with for the past few days. I'm currently on the clean phase of my 2nd application on my 1995 Acura Integra (LS, Non-VTEC) and I was just debating what to use for my rinse phase. I used Valvoline for the Clean/Rinse phase on my first application and I used Havoline for my current Clean phase. I have a bunch of synthetic that I have stored in my basement that I'd like to use up though, and was wondering if I'd likely see the same results using a Group III synthetic such as Pennzoil Platinum or Havoline Synthetic as I would using a conventional like Valvoline, Castrol GTX, Quaker State or Havoline. Any thoughts? If I would get better results using conventional, I'll just continue using that. Thanks a lot! :)
