Is Chevron Supreme still Isosyn?

The Isosyn label is missing on chevron motor oils. I see it in the Delo line-up, but it's nowhere to be found on the Supreme line-up. Are chevron oils still Grp II+? I found this link that states only 5w30 and 5w20 are formulated with isosyn. Does that mean 10w30 and 10w40 aren't?

Well, I guess if you beleive what Chevron is saying on that web page then, only the 5W20/5W30 are formulated with Iso-Syn technology. So, I would say that the 10W30/10W40 are not! Have you checked other sites? Did the 10W30/10W40 use to have Iso-Syn? When I did buy Chevron oils (5W30), I would often see bottles on the shelf both with and without the Iso-Syn wording on the bottles. I'd grab the bottles that did say Iso-Syn just for my own comfort. Not that the bottles without the Iso-Syn labeling was a lesser quality oil, IDK! Also, this isn't to say that I won't again buy Chevron oils, it just means that I haven't seen any lately or at the price that I want to pay. Last time I bought Chevron oil, I paid <$1/qt.

First, the supreme line should be phasing out, in favor of havoline. You can now see Chevron Havoline on store shelves. Second, you have to realize that "isosyn" is more of a philosophy than anything. When I was at the Chevron yearly sales and tech meeting about two years ago, all this was discussed by their lead chemists. Iso Syn is the holistic consideration of optimizing basestocks and additives to achieve a desired performance. Might it mean the use of group II or II+? Sure, but it doesnt guarantee or imply anything. Sort of a gimmick. Doesnt mean that Chevron and Havoline oils arent excellent, it just means that it is as much a sales game as anything.

It appears the term "Isosyn" is being phased out, and Chevron is now using the term Isosyn technolgy on their website. They don't seem to mention it anymore on their motor oils except Delo. Since they claim they invented modern hydrocracking and most companies use their technology, hardly seems a gimmick? Before The ISOSYN name reflects Chevron's advancement in lubricant technology. ISO represents Chevron's revolutionary Isocracking® and Isodewaxing® base oil manufacturing processes. SYN refers to the synthetic-like performance delivered as a result of optimizing their premium base oils with specialized additive formulations. http://www.chevron.com/products/sitelets/refiningtechnology/isocracking_2a.aspx http://www.chevron.com/products/sitelets/refiningtechnology/lube_tech3c.aspx http://www.chevron.com/products/sitelets/refiningtechnology/lube_tech3d.aspx http://www.chevron.com/products/sitelets/refiningtechnology/lube_tech3e.aspx Now http://www.deloperformance.com/products/isosyn_technology.aspx http://www.suncoastresources.com/ISOSYN_Brochure.pdf

Im telling you specifically what the Chevron chemists stated time and time again. Chemists != Marketing people. IMO they were trying to play off of the fact that they pioneered some of that stuff. You quoted it... The main key is this: "optimizing their premium base oils with specialized additive formulations" Doesnt imply a ratio, quantity or guarantee of anything. It is a holistic blending process, versus buying basestock from one manufacturer, an add pack from another, and mixing.

u know what. Every brand of motor oil is good. Just change your oil on time or owner manual. I change every 5k with the chevron supreme. I am not a fan of synthetic oil... I use chevron supreme because I believe it is better than other oil, and of course I pay $2/qt.

And Im not saying that supreme, or havoline is not good (great) oil. Im just saying that it seems that the term isosyn means one thing to the chemists and has been marketed to mean or imply something else.
