Having owned and sold 16 different vehicles over the past 25+ years, I can attest to one thing about synthetic oil with absolute certainty. The one who benefits most from using synthetic oil is not the owner of the vehicle, it is the NEXT owner of the vehicle!

Group III hydrocracked ISO dewaxed "syn's" are
Castrol Syntec
Pennzoil Synthetic with pennzane
Quaker State Synthetic
Havoline Synthetic
Amsoil XL7500 series
Citgo synthetic
Shell synthetic

and others.
Full PAO ester based synthetics include
Mobil 1, Delvac 1
Amsoil(all others beside XL7500 series)
Motul
Redline

Chevron must be really confused
If you go here you can find a little more about the group II's.
http://www.chevron.com/prodserv/BaseOils/isodewax.shtml
I would say that the regular chevron supreme would be a group II+, and their full synthetic supreme is a full group III. But like a said for $1.08 a quart there is not much group III in that regular oil
Lower Formulation Costs.
Increase Profits.
Improve Product Quality.
If you currently use Group I base oils, you can save as much as 10 cents per gallon when you blend API SL or CH-4 Engine Oils by switching to ChevronTexaco Group II base oils. Moreover, changing now to our modern, hydroprocessed base oils will enable you to move smoothly into the next generation of automotive lubricants.

Group II Base Oils: Performance
Quite simply, Chevron Lummus Global's ISODEWAXING® technology builds better neutral base oils. Instead of using solvents to remove the wax, the ISODEWAXING® catalyst reshapes the wax molecules and converts them into high-quality base oil. (Learn more about Isodewaxing.) Group II neutral oils have several important performance advantages over solvent extracted/solvent dewaxed base oils (Group I):

Let me suggest to you that you read a manufacturers MSDS for current info instead of pulling old files out of their library. The Chevron Supreme has been a Group III long before GpIII's were considered synthetics. If you had attended the meeting in Houston of the National Petrochemical & Refiners Assocation in 1999, this issue was addressed. Had it not been for litigation between Castrol and Mobil concerning the GroupIII's being synthetics, they would still be considered a high grade dino.
Looking over your list, you have the Havoline listed correctly as a Gp III synthetic, it is the exact same product as the Chevron Supreme. Of course, this is really not going to mean anything in the near future since Chevron and Texaco merged and now Shell has bought both companies. Supposedly, according to Shell, the Texaco lubricants are to remain for the next 5 yrs, after that is questionable. Chevron will be history. But one thing about the oil industry, you can't alway believe what they tell you. Also, you show Redlline as a full PAO synthetic, that is not correct as it is a proprietary blend with LOTS of moly.

Labnerd,
Where did you get the information that Shell bought, Chevron/Texaco? I work for Shell and I haven't heard anything about it. If you read it somewhere send me a hyperlink. The latest info. I have, which is public knowledge (Or I wouldn't be able to write this) is that Shell bought out Texaco's refining and retail side; that's why your either seeing or will see all the Texaco gas stations being switched to Shell. Also, the Texaco (a number of them anyway) refineries were in the deal and they're now "Motiva" (that's the Shell refining side). All retail products still remain "Shell" due to the public reputation. Now, Chevron and Texaco "merged" which in means Chevron bought the rights to Texaco's remaining businesses (not sure of exactly which ones).
MSParks,
What do you know about this "Royal Purple"??? I can't get any tech. info. from them on their products. Is there somwhere I can go to read about it (Other than the Royal Purple website)? Do you know anybody that has tried it?

Red Line is a Polyol Ester basestock w/ detergents. It is *NOT* a PAO basestock. It is a group V lubricant...the best out there, and the only one that can lubricate hot metal.
