dexos-qualified Pennzoil synthetic?

[rrrrrroger]

Does it exist? I didn't see any at the walmart.

Maybe I'll go with the Quaker State synthetic instead (it has the green dexos symbol on it).

I'd go for QSUD if it is Dexos. That means better base stocks and lower Flash Point.

I seem to recall QSUD being iffy on Dexos, "meets Dexos" type statement.

If it is fully certified Dexos it is a good thing even if you don't own a GM.

Pennzoil Platinum
Pennzoil Dexos Synblend
QSUD
QS synthetic blend
All are listed and DEXOS certified.

Platinum and Ultra: Dexos certified = ?. Surpasses Dexos = most likely.

You dislike Pennzoil synthetic?

BTW the Quakerstate is handing-out $20 rebates for QSUD. I applied for mine. And their oil says "exceeds dexos" not that it is certified by GM. :-( Carmakers make things so difficult and might void the warranty if it isn't certified.

Roger, QSUD and Pennzoil Platinum are both Sopus/Shell. I like either one.

QSUD is my favorite as the add pack focuses more on anti wear than the cleaning properties of Pennzoil Platinum. If there is even that big of a difference between the add packs of the two is not really known to me aside from the marketing.

Sometimes one has certs the other one doesn't.

Good info!

Antiwear is more important than cleaning since the station wagon is brand new.

Because that's the official dexos1 list. If you don't trust it, your best bet is to only buy dexos1 oil from the dealership or M1, which always has the logo on the bottles, and then keep the bottles for any future warranty concerns.

 

[rrrrrroger]

Yeah it's official. I'm surprised they didn't say somewhere "This is an official General Motors website," so we'd know it's the real thing and not some Nigerian owned scamsite. ;-) This also tells me it's safe to use Pennzoil Synthetic (though I don't understand why they don't have the green dexos1 on the label)?

I am surprised to see 0w-20 and 5w-20 oils on the list.

QUOTE:
"The dexos™ licensing program is administered by The Center For Quality Assurance (CQA)..... Licensed Blenders manufacture dexos™ using previously approved additives and formulations obtained from additive suppliers. Currently there are four additive suppliers with multiple approved dexos™ formulations. These are Afton, Infineum, Lubrizol and Oronite. Contact your respective representative for assistance on the best formulation for you.

"Licensed Rebranders purchase fully formulated dexos™ from a licensed Blender and repackage it under their own brand name(s). To begin the licensing process, all prospective licensees must submit a completed request form and a 5-gallon sample of the candidate oil to CQA for testing and qualification."

I think it's just a labeling issue (once again, like with the SN rollout) with the SOPUS products. I've seen some with the logo, and plenty without. The ones from them I've seen most reliably with the dexos1 logo are, ironically, the Pennzoil synthetic blend bottles.

I've seen the 20 grades up here from Castrol with the logo on them. They're actually quite common up here. I hope it doesn't cause confusion or issues, since the idea behind dexos1 was for consumers to be easily able to identify the appropriate oil. Is a 5w-20 dexos1 suitable for a 5w-30 dexos1 application? We know that for VW, it doesn't matter so much which viscosity is chosen, as long as it meets VW 5xx.xx. Is it the same for GM?

 

[rrrrrroger]

VW actually tests the oil to make sure it passes (they want to make sure the camshafts are protected from the high pressure pumps). GM doesn't test the oil, but just verifies you are using 1 of 4 additive packs.

 

[SteveSRT8]

^^^please explain how "testing" differs from "verification".

You seem to imply that VW actually dyno's an engine for every brand of oil? I seriously doubt that info.

 

[rrrrrroger]

Yes VW does actual mechanical tests on the oil (or so I've been told by VWforums). No not with an engine. VW has a problem with premature wear in their camshafts and turbos, so they only let europeans use certain VW-tested oils.

 

[SteveSRT8]

No offense, but "I heard it on a forum" is questionable data at best.

I appreciate your info but I am reserving judgement on VW's testing procedures!

Perhaps, but that still doesn't explain what happens warranty-wise if someone uses dexos1 5w-20 in a dexos1 5w-30 application.
