    Mobil 1 0W-40 ESP, 2019 CTS-V, 3,000 Miles...

    I took a sample from my 2019 CTS-V with just under 5K miles. I changed the factory fill at 1,890 miles and went with the new 2019 Corvette spec Mobil 1 0W40 ESP. This is NOT the M1 0W-40 Euro formula. So far looks good after 3K miles with a TBN at 5.1, so will run it for at least 5K miles...
