On another forum, it was suggested that all 5W/20 motor oil is a synthetic blend at minimum. Is this true? If so, how "synthetic" is Havoline 5W/20?
Does that mean their 10W-30 is NOT a blend?quote:

Synthetic blends are a dino based oil with a percent of syntheic. According to BOBISTHEOILGUY oil companys can add as little as 10% synthetic to a dino and have a syntheic blend. Or as they called it in the old days semi syntheic.quote:

Minimum dose required? And just who sets that standard?quote:

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.
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."quote:

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.
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..quote:
