GM updated dexos 1 list

[sopususer]

I noticed that as of 2/10/13, GM has updated their list of "dexos approved" motor oils. Looks like BP has signed on with a variety of Castrol oils. Guess we'll be seeing the green label on Castrol soon?

GM Dexos 1 list

Difficult to miss out on extra sales for a few cents per quart. Now if V could make a product good enough to qualify.

I'm sure 'V' can make a product "good enough to qualify" they just chose not to pay the vig.

I'd rather use non dexos1 certified 'V' full syn in my Cruze turbo than certified ACDelco or Pennzoil semi-syns.

Someone at Castrol must've run the numbers and figured out they were losing tons of money by not having the approval.

Why are some Castrol oils listed as BP Lubricants and others listed as Castrol Ltd? Wonder why Mobil 1 0w-30 isn't in the list too?

I'm sure they make a good enough product. They don't want to pay the royalty.

What I find interesting is that some 5w-20's are on that list. I got a little concerned when a UOA came back with a 5w-30 having sheared into a very thick 20 weight. Especially with turbo vehicles out there that really beat up on the oil, I wonder if a 5w-20 is a sufficient grade for protecting the turbocharger.

M1 5w20 was added.

I suspect the 5w/20s have been added because some of the new GM engines, like the one in the new Malibu, specify 5w/20. I don't think this means you should use 5w/20 in a GM car calling for 5w/30 just because the 5w/20 is Dexos1-approved.

Ford deals with the 5w/20 vs 5w/30 issue by having a separate spec for each. GM looks to have gone a different direction.

 

[sciphi]

My (perhaps irrational) worry is that a owner with a turbo engine will look for the dexos1 symbol, grab some 5w-20, and frag the turbo. Then they'll get all huffy, demand a new turbo under warranty, and get denied since they used the wrong grade of dexos1.

My owner's manual says use dexos1 oil, with no mention of grade. GM either did some research saying their specification is fine for turbo use, or is betting that the turbo will last 100k miles/5 years on 5w-20, at which point they'll be off the hook for replacing it.

I'd guess that the BP listed oils are the ones we see here in NA and the Castrol Ltd are the ones the rest of the world gets.

Both BP Lubricants oils and Castrol Ltd oils are listed as "Global". But, you may be correct.

Thanks for the list. The one thing I see is a listing for Peak performance after seeing a voa of Peak syn. I wonder about those who got on this list.

 

[Hokiefyd]

I was just about to say that the owner's manuals of these vehicles probably say to use a dexos1 oil in such-and-such grade, meaning the multiple dexos1 grades should be a moot point.

Until I read...

...Very interesting indeed.

Is there any oils that would fail there cert. test? aside from the ones we get warnings about from PQIA. Seems like this cert. is just another moneymaker for GM. Bring us any average oil and your checkbook and we will hook you up...

Just one more reason I will never buy a newer GM product.

Yep, I'm pretty sure most any full synthetic or syn blend would be "approved" if the maker wanted to pay for the certification and royalties. I'm glad some oil makers are deciding to skip the dexos approval. If every auto maker followed suit, it would end up significantly increasing the price per quart for oil. Why does GM need to make a few cents off every quart of oil I buy when I'm putting it in a Ford?

 

[The Critic]

It looks like the $17.27 five-qt jugs of Castrol GTX SynBlend at WM will soon be the cheapest Dexos1 approved oil that you can buy.

 

[TTK]

Dexos 1 is a higher standard than SN/GF5.

 

[TTK]

Just got some Havoline 5w-30 full synthetic at a good price and it states on the back "Meets or exceeds Chrysler MS-6395, Ford WSS-M2C046-A,GM-4718M,GM-6094M,GM Dexos 1, and Honda HTO-06". But, no Dexos green logo, so I suppose they are not paying the license fee. In fact, no Chevron oils are on the list.

True, but many don't seem to "get it"...

I now use dexos1 and/or ACEA approved oils in my Fords, screw SN/GF5...
