The GM OLM light should be followed. After all, you are using a better engine oil than the OLM engine computer assumes you are using. The OLM software algorithms are very good when it comes to determining oil life, taking into account temperature extremes, loading, etc., very sophisticated and better than anybody's guessing.
Since your Cruze uses a cartridge element style oil filter (no canister), then Purolator should be "OK" to use, it was the can-types that were tearing. (Purolator would not allowing tearing in a cartridge since its so visible to the owner...). Still, I'd prefer any Fram cartridge in there due to better filtering action.
