So when my LT1 has higher mileage, and still under warranty. Maybe i should ask for dexos so my engine blows. Then i get a brand new one

 

Remember the days of detergent and non-detergent oils?

 

Yeah, straight SAE30 no multi-grade ******** no "W" just straight 30 weight!
now you have stuff like 0w-20 a 0 weight oil that acts like a 20 weight... what's next, WATER:rock :

 

I have read on the internet that there is a new super oil coming out. It's a synthetic blend that is a -11.3 and runs to +57.5 viscosity. This is to be used only in Corvettes.

 

As long as I can still get bacon, I can live with the rest.

 

And if it's on the internet, it must be true. You're not allowed to lie on the internet!

 

We still use SAE30 in our Cessna 172. Non-detergent

 

Yes, I'm aware that dexos is not an oil but it represents a quality of oil that is inferior to Mobil 1. And in 2014 the base C7 Stingray did NOT have Mobil 1 as factory fill- there has been a huge amount of confusion on this issue which is part of my disdain for GM's marketing ploy that they call "dexos". They used this blended oil for cost savings because Mobil 1 wouldn't yield.
There has been so much push back on this issue that in June 2015 GM issued a bulletin to dealerships to start using Mobil 1 on the warranty oil changes ( I have read the bulletin that was shown to me by my service mgr.) but even with that some dealers are still filling with the blended oil rather than the Mobil 1 or are wanting to charge the customer an upcharge, as seen on this forum. On my last change under warranty, even though the service advisor wrote Mobil 1 on the work ticket when I saw the ticket after the work was done the Mobil 1 was scratched out an the tech wrote in "Dexos oil change performed." I couldn't hardly believe my eyes, the service manager had it redone with Mobil 1 when I brought it to his intention. A different service advisor commented, "at least he wrote down that he used the different oil."
Lastly, my Vette is wet sump and currently there isn't an oil filler cap that fits that's branded Mobil 1. I will likely do all the oil changes from here on- I just don't want the "Dexos" labeling on my Vette!!

 

You really need to chill. You could get 100,000+ miles on your C7 running that blended Dexos spec crap. If there's been any advertising campaign a small step from a lie it's from Mobil who has convinced an awful lot of people that their oil is so far superior to everything else. That's simply not true in today's engines.

 

Ah, the good ole days, when you poured a quart of 30 wt. in winter and it ran like molasses and oil changes were recommended every 1K miles, of course the oil was only $.35 a qt.

 

Hogwash. Provide some evidence to support that the 2014 didn't come with M1.

I have to laugh at the reputation M1 has. People act like it's some magic elixir that will prevent any engine wear for hundreds of thousands of miles. It's not really any better than any of the other so-called full synthetics on the market, and worse than some. You're body will wear out before an engine run on Dexos synthetic blend in normal street use.

 

Yeah, but don't forget the average income was probably about $2500 a year.

 

How about this news release right here:

Read it carefully, Mobil 1 was chosen as factory fill for the 2015 Z06 and the 2014 Stingray with the Z51 package. The base model came with the blend as it's factory fill at least for the first part of 2014 production.

I only use FULL synthetic. It would not matter which oil I use, but Mobil 1 FULL synthetic is provided by GM for our Corvettes.

 

And then let's not forget Malcolm Baldrige.

 

I would think a blend would be better for break in, to at least seat the rings and then to the full. My 2014 base had the blend initially.

 

My dealership told me that my 2015 Base C7 did NOT have Mobil 1 as a factory fill. They said they would put Mobil 1 in for all Corvette oil changes at their dealership. I changed the oil myself at 800 miles to Mobil 1 EP.

 

FULL synthetic doesn't mean what you think it does.

http://www.caranddriver.com/columns/...mantics-column

There is not one single automotive oil available in the U.S. that is a true full synthetic, meaning man-made from long-chain polymers. All "Full Synthetics" available are refined from either a natural mineral oil base stock or from natural gas (Penzoil Platinum). ALL. Including Mobil 1.

And Mobile 1 is used in your new Corvette because Mobil has signed a marketing agreement with GM. If you look at independent oil tests, you'll see that M1 is really nothing special compared to other premium oils available. It's not terrible, but it's certainly not the best. That said, in normal street use any oil that meets the Dexos standard will, if you change it regularly, ensure that premature engine wear is the least of your worries.

 

I stand, possibly, corrected. Although that conflicts with everything else I've ever seen.

 

We changed the oil on our 15 base ourselves and it had a green tint to it ,Dont think it was Mobil 1.
