After comparing the PDS of these oils side-by-side, it appears that these oils are, essentially, one in the same. The write-up for each is pretty much identical, as is the technical table at the end (with viscosities, pour points, etc).

I understand from various posts that the additives may be different. I'm not looking to start a which-is-better thread. I'm merely interested if anyone knows if there are, in fact, real differences between these two oils. I've seen one VOA for Chevron Supreme in the 10W-40 grade...not much about either oil otherwise that I found with the search function anyway.

Anyone know for sure what the deal is with these two oils? Same product, different bottle?
 
I'm pretty sure they are the EXACT same oil. There was rumour on this borad circulated recently about Chevron dropping the Havoline line-up, as it was a complete over-lap with their own....
 
I had heard that Chevron had moly while Havoline didn't. I'm not one to get all flustered over a list of additives, but I'm just curious if they really are exactly the same oil.

I've got Chevron Supreme 5w30 in both my 2007 vehicles now, and it seems to run real good in both. I like how both engines sound now compared with the Pennzoil Platinum 5W-20 that was in them before, but that's likely a difference in grade rather than brand/type. Either way, I can get cases of Havoline DS at Sam's Club for $2.77/qt every day, so I'm liking that option instead of hunting stores for sales and rebates. I wouldn't mind if the Havoline brand was dropped, so long as its shelf space was back-filled with Chevron Supreme.
 
They are rumored to be the same however, I think in the past the Chevron had LESS moly than Havoline. I have 2 cases of CS that I got at the past Kragen sale in September, but haven't got my rebate yet. My OCI's are every 6 mos because I never hit 5k miles.

-Needless to say, that's the last time I want to deal with Kragen rebates.
 
Does anyone know if Chevron is a blender or do they produce their own basetocks used in Havoline and Chevron Supreme?
 
I believe Chevron actually held the patent on the hydrocracking process or something like that, and practically "invented" the Group II+ oils. Or, maybe I've been reading too much of their marketing literature.

I do believe they do their own base stocks.

So is it only Shell and Chevron that produce their own? They are the only two who produce at grp II+ for use in their conventional oils?

I don't know that they're the only two. I read that Chevron long held the patent for whatever the specific process is, and that they "invented" the Group II+ type. I'm sure others are formulating their own today.

"By using Chevron’s all-hydroprocessed Group II base oil you can produce GF-4 quality lubricants with a simple one step blending process." That makes it sound like Chevron does their own refining.

This is where some of that comes from:

Chevron is the one that developed hydroprocessed oils. They in-turn licensed this process/technology to other oil companies.

Group II+ producers in the USA are Chevron, Shell, Exxon/Mobil, and Conoco/Phillips. Group III producers in the USA are Chevron, Shell, and Exxon/Mobil.

Does this mean that all those brands have II+ basestock in their conventional and not grp II? Is it really splitting hairs to compaire a grp II to a II+ conventional oil?
 
Actually they do not. The only oil I know of in the Shell line that uses Group II+ is the Pennzoil conventional 5W-20, 5w30, and 10w30, and the Shell Rotella T 15w40 and 10w30. The rest of the conventional oils that Shell makes use Group II.

The last I heard, the only Group II+ product Chevron was making is their Delo 400 line of products. I believe most of the Group II+ that Conoco/Phillips makes they sell to others, as does Exxon/Mobil.
 
Is it really just splitting hairs though? When you compare a conventional that usues Group II vs ii+? What's to gain if you are following a reasonable OCI given your driving habits?

If Shell uses exclusively their own, the fact that there are so many other manufacturers who sell to other people suggests that somebody out there is using the fluid, does it not?

Are the uses simply not motor oils?
 
Yes Shell, Exxon/Mobil, Conoco/Phillips sell to other blenders. The base stocks are used in motor oils, ATF, gear oils, hydraulic oils, etc. For one example, Schaeffer's 7000 series oils are a blend of Group II+ and some PAO. They are getting the Group II+ from Someone.
