Mobil 1 EP 0W-20 Dexos 1 Gen 2
3520 miles on oil
6020 miles on 2022 GMC Sierra 6.2L
Both samples filled from same container and shipped on 30 Nov 2022
Blackstone (Fort Wayne) report 19 Dec 2022
OAI (Indianapolis) report 30 Dec 2022
OAI was a pre-paid USPS first class, no tracking # and my post office said the zip code on the mailer was not a valid address. OAI said that the sample was received by them 28 Dec. I compiled the reports for easier comparison.
