So...you won't see it anywhere but a dealership until probably September or so.

And that oil is NOT what they are calling for, and is not DEXOS2 approved. Just saying of you are one of those "must keep warranty intact" guys, you should be using a Dexos2 approved oil, and have proof.
Will using a non approved oil do anything bad? Probably not, but if push comes to shove... You ain't folloing the rules.. Just saying...
oh and I've got a case of the 0-40 Euro blend M1 in the garage for my old M3... Some of it may have found a way into the corvette at some point...lol, but all of the required oil changes have been done by the dealer on GM's dime so far. That changes Friday when it goes in for the MRC upgrade and an oil change. (I'm being lazy and trust this dealer...)

not sure about later year c7s but the manual on my ‘14 states to use a synthetic 5-30 dexos1 certified oil. pennzoil platinum qualifies and it tests as well and even exceeds some amsoil tests over mobil one. used it without incident for many years in my c6 and use it now in my dry sump c7. manual also states the change interval is 7500 miles which i adhere to. a friend gave me 4qts of mobil one 0-40 a couple years ago but i never used it. i live in southern CA so the car is not subjected to cold weather and summer weather is in the eighties or less most of the time.

10W-30: Viscosity, @ 40ºC, cSt (ASTM D445) 63.2
HTHS viscosity, mPa•s @ 150ºC (ASTM D4683) 3.0
Pour Point, ºC (ASTM D97) -42
5W-30: Viscosity, @ 40ºC, cSt (ASTM D445) 61.7
HTHS Viscosity, mPa•s @ 150ºC (ASTM D4683) 3.1
Pour Point, ºC (ASTM D97) -42
0W-40: Viscosity, cSt (ASTM D445) @ 40ºC 70.8
HTHS Viscosity, mPa•s @ 150ºC (ASTM D4683) 3.6
So, unless you want to argue that 70.8 is smaller than 61-63 you will need to admit that 0W-40 oil is thicker at startup than 10W-30.

I thought I read somewhere that in Europe, an oil can't be called "synthetic" unless it is actually a full synthetic. If that is true, wouldn't the 0-40 Mobil1 "Full Synthetic' oil that is labeled as such(the 0w40 oil that is sold in the US as the European Formula be a true synthetic?

All 19's are now filled with the new 0w40 at the factory. The LT1 in 2019s is the same engine as in your 2014.

40C equals 104F, so that is considerably warmer than most startups. You would expect the crossover point of equal viscosity for 0W40 and 5W30 to be about that temp. Below that temp, 0W40 would be thinner, and above it thicker. Yes, yes, I know, your data say 63 versus 71, not the equal crossover point. But there is some spread in allowable viscosity for the two ranges. And at that temp and viscosity, only about 5 degrees C will change the vis by about 8 cSt. The point is that at a true startup temp of 70F or so, and especially at a winter startup temp of 20-40F, you can be sure the 0W40 will be thinner.

This is the info I read for part numbers for the new Mobil 1 caps
Base car Part# 12686472 Price Approx $6.45
Z51,Z06,GS,ZR1 Part# 12680708 Price approx $23.12
No clue why one is more than the other

I do not know the legal rules for labeling full synthetic in Europe, but I can deduce that they are probably similar to ours. Basis for my deduction is going to the Exxon website, choosing England as the country, looking at the MSDS sheets of several English Mobil1 oils listed as full synthetic, and seeing that like the US, they contain substantial quantities of group 3 synthetics, ie, the stuff that the purists try to call fake synthetic.
"Based on the MSDS docs for Japan (where they are required to disclose the amount of mineral oil, which technically includes Group III), it appears that most Mobil 1 oils contain about 35-50% Group IV-V components (since they contain about 50-65% mineral oil). It does vary by the type and viscosity of the oil, even though they are all Mobil 1. You can find the MSDS docs on the Exxon Mobil website. I have not looked at them in a couple of years, so they may have changed, especially since there continue to be quality improvements in Group III synthetics (severely hydrocracked mineral oil).
They did not have a Japanese MSDS for Mobil 1 EP oils (last time I looked), but I have read on the Mobil 1 website where they pretty much say that EP contains more polymers/esters than regular Mobil 1 (but don't have a link for that).
However, regular Mobil1 0W-40 European Formula contains the most Group IV/V components of all the Mobil 1 oils from what I could determine, since they don't allow Group III to be sold as synthetic in much of Europe............"

I find it amusing that the new '18, which I picked up yesterday, and which was built the last week of '18 production has 5w/30, but it does have the new Mobil 1 cap.
Three days later, they started building 19s and filling them w/ 0w40. I'll changeover at my 500 mile oil change, which will be in a couple of weeks with 110 miles on it the first day.

Joe, that was true with the version of M1 0w40 from a few years ago but the reformation now known as 0w40 FS has much less PAO synthetic base oil. It also no longer meets the BMW LL spec, so I need to switch my wife’s BMW over to Castrol 0w40 now. I think the new dexos 0w40 is gonna be a better oil than the current 0w40 FS European Formula
