Does that mean their 10W-30 is NOT a blend?
quote:It's only a syn-blend if you allow group IIIs to be called synthetics. (From what I read here) and yes... this is the internet so anything goes... In order for Conoco to meet SM standards, they needed to add so much group III that it exceeded the minimum dose required to call oils syn-blend. So with that in mind, it only made sense to change the jug wording. That's why their oils in popular passenger vehicle viscosities are all syn-blends now. But that doesn't excuse their group II oils for being subpar/not meeting the SM ratings. [ March 27, 2006, 04:55 PM: Message edited by: Triple_Se7en ]

quote:S-Oil in Korea uses Chevron's licensed hydrocracking and isodewaxing process to make their Ultra-S Group III, which is what ConnocoPhillips uses. Ultra-S base oils are not "cheap" or "low quality." What they blend this with is their own Group II, not "cheap conventional base oils."
Originally posted by Ken2: ConocoPhillips (Conoco, Phillips, 76, Kendall, Motorcraft brands) imports cheap, low quality Group III base oil from Korea. They decided to use this in their SM oils as a marketing ploy, and maybe also it was the cheapest way for them to get SM using cheap conventional base oils. The CP SM oils are good oils, but nothing special.
quote:There is a rumor that Mobil 5000 is actually Group III, which could technically make it a synthetic. Did we ever settle that? I heard yes from one jobber, no from another..
