I wonder if the ACDELCO parts wherehouse will have this oil??
Theyre close to my house... they welcome 'walk ins' but cater to repair shops.

What is dexos1? Is this the oil that we are supposed to start using in the Traverse?

Does it come in any other brand, or only ACDELCO?

By reading the first two pages of comments, it looks like the new GF-5 (Dexos for GM, a synthetic blend) spec may be putting acceptable engine protection into the back seat in favor of attempting to help meet upcoming revised CAFE standards for fuel mileage (which means using 5W-20 and 0W-20 oils to also help achieve this). It also appears that to achieve better protection from these oils that expensive additives must be used to close the protection gap. That means increased motor oil prices (for Dexos-spec oil) at your GM dealer and probably even higher increases at your local auto parts store.

This was good reading and some of the comments were worth the time as well.

That Amsoil bottle it is NOT CERTIFIED GM dexos1...it is only recommended which means that the oil wasn't tested by GM or their designee to get the dexos1 license. The website link was a post to GM's website which listed the specific oils that hold current certification of dexos1 and that Amsoil was not listed. It is a matter of somantics, but certified and recommended are not the same thing and I wouldn't want somebody to be lead astray and have some warranty trouble at some point down the road.

Not certified meaning that they just aren't paying GM for the "privilege" of it being licensed. It still meets the standard.

I see they show Mobil1 5w-30 --- is this different than the Mobil1 5w-30 that is currently being beat up and has less than stellar UOA from members on here?

Or would it be an upcoming new formulation- that will show the dexos1 logo on the bottle?

Typical Amsoil retoric.....it still isn't CERTIFIED and I was just letting people know so that they can make an informed decision should they choose to use it and GM mandates use of a desox1 certified oil down the road.

Lets see, According to industry sources, Marketers that WILL NOT have an officially licensed dexos product (but that will make unlicensed products meeting dexos specs):
Valvoline
Castrol
Chevron
CITGO
AMSOIL

Marketers that remain undecided:
ConocoPhillips
Petro-Canada


Oil producers that wish to display the dexos logo currently get to pay GM a fee of $1000.00 per product license plus $0.36 per gallon they sell. Not a bad-pay day for the automaker. I wonder how long it will take for other automakers to catch on and issue their own license? Customers will of course inevitably pay the extra cost.

GM should so something similar with tires. Can you imagine the income they could get as many owners change out tires and wheels and if GM were to license tire spec's, how many would be on board with that?
