Hi all. It's been a while since I've posted here, as I found it more proper to lurk and read than blindly posting. Let's discuss the next thirty years of motor oil, and how the face of it may or may not change. I'll begin by lending my prediction, and then you lend yours, opening up threads for discussion. Alright, here is how I see it. With the current production of GTL base stocks, and the possibility that oil companies may be putting some of it into "conventional" oils, I don't see the "synthetic" marque holding it's relevancy in the future. If, again, if higher end base stocks continue being used in conventional oil production, what purpose will oils such as Valvoline Synpower, QS Ultimate Durability, and Castrol Edge with Syntec have? I look at it this way. Oils currently labeled as conventional and synthetic blend (i.e. QSGB, PYB, Phillips TA, MS5K) can do what Castrol Edge w/ Syntec, QSUD, VSP, Havoline Synthetic, Mobil Super Synthetic, and the like can do. The only oils that really seem to establish a solid difference between conventional and synthetic are Mobil 1 EP, Castrol Edge EP, Pennzoil Platinum PP, Pennzoil Ultra Platinum, and boutique oils from Amsoil and Redline. Also on this note, what purpose will dexos1 spec semi synths have when conventionals come to meet and exceed the spec. All in all, it seems that oil will in some ways revert, in the sense that there will be full synthetic and not full synthetic oils. The conventionals will become stringent cert passing, high end synthetic blends with no fancy "full synthetic" labels, and true full, PAO based syntheics will once again dominate the "synthetic" market. Again, this is my opinion. I'm not looking to violently argue with anyone, just observe various opinions. I'd really prefer that no one takes this thread to [censored] like many do, and hopefully we can all be adults and healthily discuss this subject. I could have this whole thing wrong, and at worst I'll learn something new.
