Hello to all,

Went to my local PEP BOYS yesterday and noticed the Mobil 1 oil (my favorite) didn't have the so called "Dexos" label on the bottle. However the Mobil 1 "extended" did have the logo on that version.

Can anyone tell me why the standard M1 dooesn't qualify for the logo? Or is this a plooy by Mobil to get me to buy the extended?

Yep, must be old labels as we just loaded up on M1 for our new fleet trucks which require Dexos and M1 was one of the few we liked that had the label.

Here's the whole newly updated dexos1 list. Maybe there's another favorite hiding out there?

GM dexos 1 approved list

It's the GM spec for all 2011 and newer GM vehicles. Tons of info in BITOG. GM requires $$ from the oil companies to be officially licensed. At first most of the major oil companies balked at paying for the license. Now Valvoline seems to be the last major holding out.

Here's more info than you probably want to know:

About dexos
 
I figure that if an oil says it meets the spec, that is fine. I could care less that it has the little dexos 1 symbol on the front or is on the "approved" list. Even the owners manual clearly states use dexos or EQUIVALENT oil. That calms my paranoia gland nicely.
 
I figure that if any oil meeting the dexos1 spec is good enough for the 2014 Corvette, then it is good enough for anything that *I* drive...

For me, it is the Pennzoil Synthetic Blend 5w30.
 
Dexos, among other things, takes the old standard 6094M and the 4718M which had nothing to do with each other and combines them into one. It's an all-inclusive oil so to speak. You won't find a conventional dino basestock oil that meets the Dexos certification.
 
It's an easy way to keep you from using Mobil Special conventional, which "meets protection requirements". Most oils say they exceed!
I'm kinda glad GM is doing this, it does prevent people from using substandard oils and since it's at least a semi-synthetic blend that meets Dexos1, you should easily be able to go 7500 miles for an OCI. And that'll save oil down the road.

Since Hendrick Automotive Group left Quaker State and will soon be using Valvoline in all 87 of their dealerships, I am sure that Valvoline will soon be Dexos1 approved. Hendrick has quite a few GM dealers, and will need to use approved oil.

No. Maybe exceeds dexos specifications.
 
I doubt if any oil that claims to meet all of the current standards, whether it has a nifty emblem on it or not, would be fine to use. Would be difficult to think that an oil that claims to meet or exceed API SN, ILSAC GF-5, and dexos 1 can be a bad thing. Any oil that meets or exceeds all those specs has to be somewhat robust. That they didn't go out of their way and obtain the "official" dexos emblem and get on the "approved" list doesn't really concern me. I know what is going on there with that one. I find it amazing that GM is playing this game the way they are. Cummins, Cat, Volvo, MB, VW, Detroit, etc, etc, will lay out a spec and just say use an oil that meets the spec. But not GM... No.... only use the oil with the little dexos emblem on the front. I don't buy that idea with my commercial trucks and am not buying that idea for my personal vehicles. As long as the engine oil manufacturer states that it meets or exceeds the spec, irregardless of whether it is on the "approved" list, I am fine with it. If there is a oil related problem, the OEM has to prove, according to the Federal Trade Commission, that the oil I used actually caused the problem. Has nothing to do with whether it was on an approved list or not. And truth be told, unless someone divulges the name of the oil they are using, no one probably will ask!
 
All the above is fine until there is a warranted issue.

Fine to do for yourself but may be a bit out of line to recommend it to others. A stealership can indeed stall your claim and annoy you to death with verification details.

Most will never know or care...
 
I use dexos1 licensed oil for 2 reasons:

1. If I do have a warranty issue, GM or the dealer has pretty much nothing to say.
2. Dexos1 oils like Mobil 1/Pennzoil Platinum are no more expensive than non-dexos oils.

If dexos1 oils were 2X the price of non-dexos1 oils, then people complaining might be justified.
 
I do try to used oils on the approved list for my 13 Silverado. Right now I have in M1 5w30. It's also seen QSUD and PP 5w30 as well. I have never been a fan of Valvoline, but I'm sure they along with any other oil that claims to meet the dexos spec would also be fine and would be considered "an equivalent" by GM. However, I would not pour in a bottle of anything, GF-5 rated or not, that didn't at least mention dexos.

Based on the information in this pdf, the dexos spec is more demanding that the standard GF-5 certification. In my opinion, for warranty purposes:

GM approved dexos oil: CHECK
Oils (like Valvoline SuperPower or Amsoil) claiming to meet dexos: CHECK
GF-5 oils that don't mention dexos: DON'T THINK SO!
