Frankly, if you go to the Mobil 1 site, and compare, the GM 0w40 to the Euro 0w40, the European mix has better additives for the motor... and can be had for about $25 for a 5 quart jug at WalMart.

3 free oil changes from my GM dealership, after that I do it myself.

Three? is there a time or mileage range ? Had the 500 one done at the Dealership and they had to go all over to get the oil..............

2019 Corvettes only get 2 free from GM. In previous model years Corvettes received 3 and all other vehicles received 2, but now Corvette is 2 and every other Chevrolet is 1.

You did have a year, but I do not know if that has changed

Need to find another dealer. This is way late in the game for a dealer to not have the ESP oil.

My dealership adds 1 on them maybe another dealership is in the future There is no time limit at my dealership, not sure how others work

Dealership adds one on them

Do you understand that Wally World oil is not Mobil 1 0W-40 ESP Dexos 2 ??

Do you understand no need to come off as a pompus ***? No......didn't think so. Had I of known that I probably wouldn't have made the recommendation I did. Sorry you're above shopping at Wally World.

Dave Schotz

You're right... Wally world isn't DEXOS... but if you goto the Mobil1 link I provided... it shows you that the Wally World stuff is actually 'better' for the motor... than the Dexos.

GM reduces the Zinc content... to save the cats for 100K+ Miles... thus why the Dexos version says 'Emissions System Protection'... that's code for 'less engine protection'.

​​​​​​​Speaking of pompus asses, I think the award goes to the poster that turns nasty when they're found to be wrong. You made an error and got called on it. Get over it.

What is frustrating about these oil threads is that they are often discussed at length, and good information is provided, and yet all too short a time goes by and the misinformation creeps back in and we're back at it again.

The Mobil 1 link you provided is not the product data sheets for the oils you are discussing. Those are only consumer information charts. The link you provided is not discussing the chemistry, and so your point is not proven. Furthermore, you are incorrect basing your argument on the Zinc dialkyldithiophosphate (ZDDP) anti-wear additive in motor oil. While zinc has been the is the most commonly used anti-wear additive, it is by no means the only additive that may be used. By not examining the chemistry, you cannot make a claim on inadequate anti-wear additive.

It should be instructive that in the big thread here on the Mobil 1 0W-40 ESP Dexos 2, our resident petroleum engineer could find noting intrinsically wrong with the oil except that he was unsure about the life of the viscosity index improvers on long drain intervals. That was all. It is also instructive to note that the oil fanatics over at bobistheoilguy have had nothing bad to say about the Mobil 1 0W-40 ESP Dexos 2 chemistry. We will only know about any shortfalls in the viscosity or TBN numbers after people run and post their oil analysis.

To conclude; You can only make a sound verdict on oil if you know the chemistry. The oil companies will provide some limited public information on viscosity, pour points, and volatility, but little on chemistry. The only way to really know the chemistry of the additives is to spring for a VOA (best) or UOA test yourself and post the results. Otherwise we rely on our petroleum industry members and lubrication enthusiasts here or on bobistheoilguy that do post information or results. From what I've seen, the Mobil 1 0W-40 ESP Dexos 2 is superior to the European oil for our engines, especially for the Noack volatility numbers. I will continue to use and recommend Mobil 1 0W-40 ESP Dexos 2 for the C7 Corvettes.
