Howdy Bitog,
Purchased a new 2017 ATS 2.0T. Dealer put in 0w20 for delivery. After several calls to multiple parts departments it was confirmed that this engine specifically calls for 5w30 Dexos1.
Since Dexos1 Gen2 was designed, in part, to specifically address the LSPI history on this engine, should GM not be mandating that D1G2 be used? If so, the parts database, and the service database, both call for standard 5w30 D1, which does not reflect the new spec.
Questions:
1. Should I leave the 0w20 in and wait until the next OCI?
2. Should I request it be changed with D1 5w30?
3. Should I request it be changed with D1G2 5w30?
If #3 is the consensus, is there a TSB or official communication from GM that I can leverage to get the D1G2 5w30 in there? Keep in mind I have 4 years 80,000 KM free maintenance. I want to make sure they use the correct spec and viscosity.
