Tbere's no such thing as an oil having "Dexos in it."

Until you understand what Dexos is, and isn't, you might want to refrain from posting about it.

 

You know what I mean the logo !!! Here you go Confusing as it may be, dexosâ„¢ is not a brand or type of oil at all. Instead, dexosâ„¢ is a specification concocted by General Motors along with a license the auto maker sells to oil manufacturers. Any brand of oil that displays the dexosâ„¢ logo is adequate to meet GM warranty requirements.... And Mobile 1, meets and exceeds any other oil and that's why it goes in their high performance cars not their pick ups !!!

 

Happy Now ..!!! since you didn't understand I fixed it for you bc you're special !!!

 

Actually, meyerweb is special. He's developed and earned a very respected reputation on CF. Postcount (as of this writing): 2338 (his) vs. 69 (yours). Hmmm. If you had taken the time to read his posts before accusing him of the very thing you are guilty of, you would find that he actually generates information/data (rather than speculatory drivel or re-posts). And he writes well.

He also knows how to spell the name of the oil you're arguing about. You do not unfortunately, and it really undermines any point you're trying (unsuccessfully) to make.

Your assertion that somehow Mobil 1 5W-30 (note that the proper spelling of this product is not spelled like the city in Alabama, does not mean able to move or be moved freely or easily, or refer to a cellular phone or handheld computer) is required to prevent LT-1/LT-4 motor issues is FALSE. This is NOT the reason for the bulletin, and per even the 2016 owners manual, any dexos1 certified 5W-30 oil meets the warranty requirements for street use. Track use is not the topic here.

The entire Mobil 1 5W-30 service bulletin debate/debacle has to do two factors: the 24 months of 4 or 5 free oil changes we "paid for" under the Chevrolet Complete Care program (the actual reason), and (really because) the Corvette brand manager/marketing machine recognizes Corvette owners' reverence of the Mobil 1 brand image. Sure it's good oil, but it's not unicorn blood.

The fact that Mobil 1 5W-30 is the factory fill in all C7 Corvettes (yes, this is confirmed) has nothing to do with it being the special sauce preventing a motor grenade. It's marketing, it projects a premium image, and for the 0.1% of use cases, it may have some quantitative benefits over the GM dexos1 certified semi-syn 5W-30 (or any dexos1 oil for that matter).

The 500 mile oil change update for dry sump engines had to do with the unique silicone sealants in that system breaking down the anti-foaming agents in the oil (yes...even the miracle factory fill Mobil 1 gets compromised). The wet sump is not covered by this bulletin and will go by the OLM.

The LT-1/LT-4 motor failures that have occurred are most likely to have been WITH Mobil 1 5W-30 in the pan (because it's the factory fill and -most- GM dealers use it for Corvettes). Certainly the low mile failures have been with Mobil 1. I think it's foolish to believe that lubrication was a factor in any of these, because if it were, Mobil 1 5W-30 would be more likely at fault.

And after all that...I don't use Mobil 1. I use Penzoil Platinum Ultra 5W-30 and a Mobil 1 oil filter. But I laugh at myself EVERY time I go to Wally World and spend $70 (vs. free) when I know logically and quantitatively that the "lowly" GM dexos1 would be 110% good enough for what I do with my car. But it makes me feel better.

 

1. If respect was giving when I said there was a bulletin that I got from Dave at Kerbeck the worlds largest Corvette Dealer stating use Mobile 1, people should want to find out why not down play it ...2. I don't give a rats *** on how many post a person has it doesn't over rule a GM bulletin ..!! Theres a reason bulletins and updates come out ...not for ***** and giggles..and a keyboard God can't say it doesn't mean anything just bc they don't believe in certain oils ...period !!!!! 3. If you fire then I will fire back then I will Donald Trump anyone ..meaning I won't be nice with my words next !!! I gave and showed info of the bulletin then some people want to put the bulletin down... So that's why we are at this point ..and I don't mind we can go on and on ...

 

Try actually READING the bulletin. Here, I'll help:

The 2014-2015 Chevrolet Complete Care Program for Corvettes was designed to take into account the preferred Mobil 1 oil choice of many Corvette owners.

Now try to find and actually read the warranty booklet that came with your car. Show me where it says Mobil 1 is required.

Now find any evidence that an LT1 engine has failed because of the oil used. As XP800 pointed out, but you apparently didn't understand, many of these failures have happened on the factory fill, which is Mobil 1.

Instead of talking out of your ***, while providing zero evidence to support the idea that running a GM approved Dexos oil causes engines to grenade, find some actual evidence.

 

Ok Dick head I have a 2016 factory delivery engine build do you want to bet money or your Z06 that mobile 1 did not go into the car when building ..? Do you ? Don't think so now stay behind the keyboard and shut the F-up bc your wrong and I'll prove it to you put up your car or your money A- hole ..!! I'll be waiting ...put up or shut up ...!!! Everyone is tuned in ..Mr. know it all and if you bet I will come and collect ..I promise you that .....LMAO ...

 

You don't know WTF you're talking about. Your writing is so bad I can't quite figure out whether you think M1 DID or Didn't go into your car at the factory.

Until you spend some time on the forum benefiting from the knowledge of people who have been involved in this world for a lot longer than you, I don't think anyone is going to pay the slightest attention to what you think.

I just love people who come in here and immediately think they know more than everyone else. Grow up, listen and learn, and then maybe we'll care what you think. For now, you're on my ignore list.

 

Mobil 1 is the factory fill for EVERY Corvette coming off the line.

Good enough reason for me to keep using it. No need to call names. If you can prove that Corvettes aren't being filled with Mobil 1, please provide proof. Until then, your rantings are to be taken as the result of too much beer and ignorance.

 

Does this mean you accept or worried about essay perfect writing ? Didn't know I had to be perfect in short text, I guess I should have skipped Grad. School ..and I don't drink, you're the dumb *** if you go back and read from the start of this post all I said is there's a bulletin and I was told to use mobile 1..!!! And people said I didn't have too I could ignore the bulletin bc it was about money and promo..so you started defending with your rocket expert opinions without knowing what was said !!!! I was like WTF ..!!! Bottom line there's a bulletin stating use Mobile 1 bc it's recommended ..I called the number ..I was told that the first 500 to 600 miles uses a Blend then after a Full ...so now should I listen to the keyboard Gods or the people on the end of the 1800 number ? Remember only one of the two can reimburse me my 115k now ...
