Dexos Full Synthetic Question

Hello All,

This is my first post on the Equinox Forum and just browsing through the articles this is a great place to be. I did see that their were already forums on the "Dexos1" vs. "Dexos2" oils. Long story short, I have had my Nox for about 7 months now.. it was a 1 owner GM Certified 2012 Chevrolet Equinox with the 2.4L Ecotec I4 Engine and had 54k on it when I got it. Now I have approached 62k and used up my last free oil change, so I picked up 5 qts of Dexos from the dealer when I took it in for the coolant and transmission flush (did it for extra insurance due to it being 5 years old). I had a 2001 Pontiac Grand Am with the 2.4L Eco from 2008-2012 roughly and loved it.. used Valvoline Maxlife Full-Syn which I have found to be Dexos approved which I think is what I will use once I pass 75k miles. The reason I crafted this post was to reach out to y'all and see what your thoughts were on Dexos2? I did again see a post about it but recently received more information about it when going to the dealer and to mycertifiedservice.com (GM's service coupon website). I asked the parts manager where I bought my vehicle (GM Dealership) if they had any full synthetic Dexos in quarts and he sold me 5 qts of Dexos2 5w30 Full Synthetic GM PN#88865157. I got home and was looking at the label and it says "For GM Diesel Engines" so I proceed to call them back and asked them if it was safe to use in the 2012 nox with the 2.4, and if it would void my warranty. After speaking with the parts manager he told me that at their particular dealership it is the type of dexos they are putting in all of their vehicles they service so it would not void the warranty and that the change occurred late last month. (mycertifiedservice.com) Advertises a 6 qt. full synthetic oil change and tire rotation for 49.95. Does anyone know if Delco makes a full synthetic dexos1? I have taken it to the dealership in town where I live which is not where I bought it originally for the 2 free oil changes and they told me they put dexos1 synthetic blend in it. Just need some friendly input guys and gals.. would you put it in the engine or go find a dexos1 full synthetic to put in it from autozone or advance? The red flag that got me was it didn't have the API starburst symbol on it, also I am unsure if Dexos1 synthetic blend was used throughout the life of the engine but my last vehicle was a 2012 sonic I bought new and I used nothing but the Delco Dexos1 Syn Blend and didn't have any issues when I traded it for the nox at 98k miles. All feedback is much appreciated I'm willing to take it back if y'all think its unsafe. The dealer service department told me that they were starting to "phase out" dexos1 and start using dexos2 which I find hard to believe lol. Also bought the extended warranty as I researched the vehicle when I bought it and it covers everything but I just don't go in for oil changes as it is a very easy maintenance task.

Re: Dexos Full Synthetic Question

Dexos 1 is for gasoline engines.
Dexos 2 is for both gasoline and diesel engines.
They only use dexos 2 in Europe for both engine types.
Dexos 2 has a lower saps for emissions.
SAPS stands for Sulphated Ash, Phosphorous, Sulphur.
Saps has both pro's and cons. It keeps the oil life longer.
But it should not void the warranty.

I would, however, just get a good full synthetic like Pennzoil, Valvoline, etc. Change oil every 5,000 to 10,000 miles.
These are extremely good oils that you can pick up at Wal-Mart for $23 a 5 quart jug.

Good info...except, seems like the recommended oil change interval is in the 5000 to 7500 mile range - depending on driving habits. It is felt that 10K intervals is way too long, even using synthetic oil.

And yet some think one oil change a year is adequate. . . . regardless of the mileage, driving conditions, etc.

Re: Dexos Full Synthetic Question

just go with Pennzoil Platinum- Full synthetic.
Always available at Wal Mart for about $23 for a 5 qt jug.
Back in July, I stocked up with 5 jugs of PP... with the rebate- each quart was $2.49.... $12.47 for a jug of FULL synthetic.

this was the offer which is now expired..
but keep your eyes open and stock up when they have deals on these.

Re: Dexos Full Synthetic Question

No need to use Valvoline Maxlife unless you are using oil regardless of miles.
Over at BITOG, there are autos with 200,000 miles that don't use oil.

Oh yes! Definitely stay with what the manual suggests and if you are changing the oil yourself, keep the receipts.
Your warranty depends on it😊

They have a new offer for 2017
http://www.pennzoil.com/en_us/promot...Rpb25hbDE3Lw==

$2 off per quart for up to $48.
So that $23 Pennzoil Platinum is really just $13 and tax😂

"New to the nox" that is very helpful. "Rbarrios" thank you as well. Has PENNZOIL improved over the years? We put it in our jeep once and had yellow waxy "gunk" buildup on the oil filler cap at 1k miles so I have used valvoline since, but that was over 10 years ago. It sounds promising though. Does it seem to perform well for a 5k change on yours?. Thanks again everyone.

In my 2013 Nox (3.6V6), Ive used Pennzoil Platinum Full Synthetic- and had used oil analysis. The results were good.
The current oil in the engine now ( about 500 miles now) is the newer Penn Platinum- Full Syn made from Natural gas....
No used oil analysis on that yet. But will in the future.
Based on the Used oil analysis results, I am doing 6000-7000 mile oil changes-- which translates to 0% oil life monitor.



As for Valvoline- I do use Valvoline CONVENTIONAL oil in my 2010 3.6V6 traverse.
I go 5000 miles on that oil.
