    What the heck is Dexos?

    Specifically what is different about Dexos oil compared to ordinary dino oil or synthetic? I've searched high and low and all I can find is, it's wonderful stuff and recommended/required for newer GM engines. What is in it to make it better?
    I'm old school and still use dino oil with Zinc and other friction/wear reducers, in most all of my "older" junk. I even switched from Mobil 1 to dino oil in my LS7. I found the annoying tick went away immediately. It seems all the good stuff has been legislated out of most modern motor oils. Maybe Dexos is our salvation but, I need to know more. Lets hear from you gearheads in the know.

    Dexos is just oil that meets the standards that GM decided is best for their engines, and passed a few non standard tests.. There are many oils from several brands that meet the standard, in conventional, synthetic blend, and full synthetic.

    What's in it? Just like every other oil, a slightly different concoction of additives.

    Re: What the heck is Dexos?

    I love the comment in the Dexos writeup that "just like company (GM) Dexos is global." If the oil distributor is as serious as the corporate parent about being "truly" global the brand is in serious trouble! Wonder if you can actually buy Dexos in Europe or other third world areas?

    It's not a brand, it's simply an approval. The Dexos icon can be printed on many oil brand's labels distributed throughout the world.

    The oils in that list are available on every corner of the earth. Even generic names like Carquest and Autozone are Dexos oils.

    Re: What the heck is Dexos?

    Yeah, I get all that, I've read all that about Dexos from GM, but it really tells me nothing. I want to know what's in it and whats not in it, like ZDDP etc. I'm sure its a top secret formula, known only to the license holders that produce the stuff. I just wonder if my old favorite dino oil with the SL specification and 1600PPM ZDDP might out perform it. When the warranty expires of course.

    Well, it hasn't been blowing engines or resulting in increased warranty claims, so I'm guessing it works just fine - just like all of the other oils on the market. As far as the additive formula, I'm not sure.

    Thats because Carquest and Autozone can just buy a already licensed oil and rebrand it. That means 95% of the oils with the dexos logo are basically the same. So you are probably wasting money buying brand names with the dexos logo because the are all the same.

    Looks like the SL oils carried a zinc load of 1182 (not "1600") and even the same year group diesel rated oils were in the 1200's.

    ZDDP is not a big factor in today's roller cammed engines - and, in excess, it eats the newer catalytic converter guts.

    You can always go the aftermarket oil blenders - ASMOIL, JoeGibbsRacing (DrivenOil), and Edelbrock for their "musclecar" oils - but your cat will hate you.

    My take is that the DEXOS thing is a warm, fuzzy feelgood by GM - the same as those who obsess because their particular car has a Mobil 1 sticker under the hood.

    Exactly the point! A lot of this is just a matter of which brands have paid for licensing.


    There is one exception against using whatever you want - it will be worth isolating actual Dexos labeled oils while your vehicle is under warranty...

    EVERY oil brand says it offers superior protection. They're all VERY close. In lab tests, one will outperform another in some category. In the real world, it's not enough difference to matter.

    My usual suggestion is:

    Go to the store, knock all of the bottles of the correct viscosity off of the shelf, and buy the ones pointing at you.

    ...Or just pick whichever are your favorite color.

    Re: What the heck is Dexos?

    Well, it's mute point with the warranty mandate to use Dexos and the Cadillac 4/48 service plan. But I'm curious. I've used the SL oils since they came out, and still run it in my old junk. I've even switched from Mobil 1 in the Vette with the LS7. It made a world of difference in that. It runs smoother , quieter and even has picked up a couple of MPG. There are SL grade oils available from a few small blenders that have 1600PPM ZDDP, though the mainstream oils did have around 1200PPM. There are a lot of other considerations, than just ZDDP. It may not be a issue with the newer roller engines, but if one oil prevents wear better than another, why not use it?
    It's just one of those things I need to know, What the heck is Dexos oil?

    Ooorrr the dealer just uses what he has on the shelf. How would the consumer know?

    I would be curious to see what the graph looks like for 2011 and 2012.
