I am new to post, but have lurked for sometime here. I have always been a die hard believer in 3k OCI's mostly using 5w30 M1 and Castrol Syntech depending on which was on sale at Wallyworld.
A few months ago, the little woman & I decided to take our 2002 Yukon XL from NC to CA and back. (It had ~34k on it at the time.) Well, I knew (from my college education) that this trip would be about 6k miles, plus or minus a bit. Being a religious (my wife says anal) 3k OCI person and liking to do my own work, I was "forced" to find a way to confidently run my "new" vehicle double my traditional OCI. My research brought me to AMSOIL and BITOG for EOCI confidence.
At my last oil change, I installed AMSOIL S2000 0w30 in both my 5.3l 2002 Yukon XL, 43k miles now and my 1996 Ranger 4.0l, 103k miles now (with AMSOIL BMK-13 dual bypass). My first impression is that this is really slick stuff! Both vehicles are noticeably running better and smoother than ever. (You guys who bash AMSOIL out there, if you have something better, let me know and I'm on it!)
The Yukon is about due for an oil change (OLS light came on at ~7500, no bypass on this one). I changed the filter (removed AMSOIL, installed a Baldwin), topped off about 1000 miles ago. I will pull a sample this weekend for UOA to determine status.
So, I am getting ready to replenish my stash of goodies for the big day and this brings me to my questions:
1) In several threads I see comments about HDEO and PCMO. Can you guys comment on the differences? I am trying to decide between S2000 0w30 (a PCMO), ASL 5w30 (a PCMO but cheaper) and S3000 5w30 (a HDEO).
2) I am also considering something with moly in it to cure a 'tick' and seek recommendations. The Yukon has had a "tick" almost since new. The 'stealer' claimed it to be carbon. I have used a cleaner, B-12 Chemtool, at every OCI early in the life of this vehicle and now add some MMO every couple of fillups. Will a moly oil cure something like this?
3) I also am considering using Auto-Rx for the last 1000 miles of this OCI, again for the 'tick' problem. Is there a good moly dino oil out there for the rinse phase? Would the moly bind adequately in the presence of ARx?
Thanks to all of you folks for feeding my long time need! BTW, my wife thinks we are all nuts!
