Snoppy,

I just dug up my receipt for my last change done by my GM dealer on 9/11/12

It shows Chevron Supreme 5W/30W with a $5 up charge for the Dexos Oil.
Also shows an AC PF457G oil Filter.

When they informed me at the middle of 2011 to upgrade per GM warranty specs on my (New at that time HHR) I happily did so for an upcharge.
At that time they were using Havoline 5W/30W with Dexos specs for all 2011 cars and trucks.
They just recently switched to the Chevron Product.
I would be more then surprised if it is not listed currently.

Moble1 5-30w....All my favorite race car drivers use it so I have to.

 

I'm sorry to say (unless GM has not provided me with an ungraded list) that neither of those oils, Chevron or Havoline, are GM dexos approved oils. I have the most recent list, which is the same one illustrated in the link above, sitting on my desk.....both dated June of this year. But when I'm at my desk tomorrow, I will make an inquiry with GM regarding this. Oh, and you do have the correct AC oil filter.

Personal opinion, at this point.....the dealer gave you a line about the dexos approval.

Question regarding the last post....if the dealer was already using what they say was a dexos oil, Havoline, why did they upgrade to another alleged dexos oil, Chevron??

Does not make sense, unless of course it was a matter of economics.

Also, the term dexos is a trademark of GM, and must be labeled on containers to meet GM requirements. If it's not there, it not dexos.....period.

 

Snoopy-

Pretty sure my last 5 qt jug of M-1, had a Dexos approved label on it.. If memory serves..

Is that possible ?

 

I guess it is.

 

OK thanks, I was hoping I wasn't seeing things..

 

I see nothing but Nascar.


What's that other stuff I'm supposed to be seein'??

 

I will be checking this out futher as soon as I find time.

Let you know what I find out.

Chevron bought Texaco.

Texaco oil is Havoline. It's been around as long as I can remember.

Specifically to SilverFox.......

Ok, I did error. However, my statements regarding Chevron and Havoline products NOT meeting/approved GM dexos requirements is CORRECT. I was referring to, and posted, the approved list of dexos2 oils, WHICH ARE FOR DIESEL VEHICLES. A serious error on my part, although my mental knowledge was correct.

This is the most recent, dated June 2012 also, approved list for GASOLINE ENGINES.......(changed in my original post also)

What directed me to locating this mistake.....sleeper's post regarding the M1. Why on earth would he ask that ????? So when reviewing the previous list, I noticed, while Mobil Exxon was on the list the name specific Mobil 1 5w-30 (et. al) were not. Hmmmmm

So I called and asked a Durability Engineer. He pointed out the error......which made me feel a little stupid because this was my responsibility.

So again, Chevron and Havoline, while providing good products, DO NOT CURRENTLY HAVE DEXOS1 APPROVAL. AND.....

IF your GM dealer did in fact, as you state (with no misunderstanding), state that those oils are dexos approved and provided them as an approved dexos oil, GM should be notified of this misrepresentation. They not only lied but committed fraud and it would be handled internally by GM. GM does not take lightly trademark infringements, as many can attest here.


By the way, I used Havoline products for many years. Traded off to Castrol for a short period of time (another story) then started using Mobil 1. Been about 20 years now.

 

Snoopy,

Here is the latest info I have found out.



1. AC/Delco Brand is the only True Dexos Oil on the market.
It is made for GM by Exxon/Mobile

2.Look at you Oil fill cap for the Dexos logo to see if your engine needs it.

3. As for the Mobile 1 Fully synthetic 5W-30W product .. It's only Mobile 1 product Dexos approved.
The other versions of Mobile 1 are not Dexos approved at this time.

4. All the other oils with Dexos labeling are just GM approved oils ... not the same exact formula as AC/Delco.

There was a computer/human glitch on my last Invoice for the oil change.
It showed Chevron Supreme 5/30 used but they had made a mistake on the year of the HHR showing it a "2010" in which that is the oil they would have installed in that vehicle unless I wanted to upgrade which I did.
They took me back thru the change records on that service and proved I actually got AC Delco Dexos 5/30 oil installed.
They also told me about looking at the fill cap to see if your car requires the Dexos Product.
They also showed me the bulk oil in stock and how they dispense it. I am comfortable with what they did to show me how the error was made.
They also made a notation on my copy of that oil change invoice so I would have the correct records on file.
They buy it in the 55 gallon drum and it is used for every GM car that comes thru requiring it.

GM dexos™ Engine Oil Increases Engine Efficiency
New for the 2011 model year, GM will introduce ACDelco dexos™1 certified engine oil as a factory fill and service fill for its gasoline engines worldwide. The new engine oil specification has been developed to help meet the increased demands for enhanced engine efficiency. dexos™ oil helps deliver increased fuel efficiency and reduced engine emissions.
dexos™ is a GM proprietary engine oil specification that has been designed to:
• Further improve fuel economy (to meet future Corporate Average Fuel Economy, CAFE, requirements) and fuel economy retention through improved viscometric properties that create less friction in the engine, which allows the oil to maintain its fuel economy benefits throughout the longer life of the oil
• Provide a more robust formulation for added engine protection that offers improved oxidation and deposit-forming tendencies and aeration performance, which enables fuel-saving devices, such as
January / February 2011
ACDelco News Page 2
Variable Valve Timing, to work optimally
• Support GM’s Oil Life Monitoring System (OLMS) by resisting degradation between oil changes
• Ensure worldwide availability of equal quality oil while reducing the duplication of a large number of
internal GM engine oil specifications, replacing GM specifications GM-
LL-A-025, GM6094M and GM4718M.
dexos™1 also is backward compatible for older vehicles; however, the owner manual oil specification in prior model years remains acceptable.
dexos™ Classifications
The dexos™ specification includes two classifications.
1. GM will require dexos™1 for global factory fill in spark ignited
engines worldwide and service fill for gasoline engines worldwide.
It will replace the GM6094M specification for most GM gasoline
engines.
2. dexos™2, required for diesel engines as well as a service fill for
gasoline engines in Europe, was introduced in Europe late last
year.
GF-5 Standard
In addition to GM dexos™, a new International Lubricants Standardization and Approval Committee (ILSAC) standard, GF-5, was introduced in 2010. There is a new API engine oil service category – SN Resource Conserving. The current GF-4 standard was put in place in 2004. The GF-5 standard will use a new engine fuel economy test, called Sequence VID (six D), which provides a statistically significant increase in fuel economy versus the Sequence VIB (six B) test that was used for GF-4. Like dexos™, the new ILSAC GF-5 standard will call for more sophisticated additives.
It’s expected that all dexos™1 approved oils will meet GF-5. However, not all GF-5 engine oils will necessarily meet the dexos™ specification.
Fuel Economy
Since CAFE standards were first introduced in 1974, the fuel economy of cars has more than doubled, while the fuel economy of light trucks has increased by more than 50 percent. Proposed CAFE standards call for a continuation of increased fuel economy in new cars and trucks. To meet these future requirements, all vehicle operation aspects are being looked at more critically than ever before.
New technology being introduced in GM vehicles designed to address vehicle efficiency and fuel economy include direct injection, cam phasing, turbocharging and Active Fuel Management. The demands of these technologies on engine oil also are taken into consideration when determining new oil specifications. Active Fuel Management, for example, can help to achieve improved fuel economy, however, alternately starting and stopping cylinders puts a lot of stress on engine oil.
To meet tough fuel economy mandates, the industry will shift toward lower viscosity oils. Testing has shown that thinner 0W-20 oil, for example, can provide as much as a 4-percent improvement in fuel economy over 15W-40 oil.
dexos™1 will be offered in these viscosities: SAE 0W-20, 5W-20, 0W-30 and 5W-30. dexos2™ will be available in SAE 5W-30, 0W-40 and 5W-40. Please check the appropriate vehicle owner manual for the proper viscosity grade.
Increased Service Intervals
To help reduce the consumption of oil while maintaining proper engine protection, many GM vehicles equipped with the GM OLMS have a maximum oil change interval that is much longer than what was considered a normal interval just a few years ago.
ACDelco News Page 3
If all GM vehicle owners follow the OLMS intervals in their vehicles as intended, GM estimates that more than 100 million gallons of oil could be saved annually.
The second generation OLMS will rely on significantly more engine operating information than the current system, which, combined with dexos™ certified oil, could allow a significant extension of the maximum oil change interval. dexos™ specifications call for improved oil robustness to support extended drain intervals over a vehicle’s lifetime.
When the OLMS determines that an oil and filter change is needed, the driver is notified by a Change Oil message on the instrument panel. The oil change should be performed within 600 miles (1,000 km). The OLMS must be manually reset when the oil is changed.
