ETOPS vs NON-ETOPS Mainteance

[Frostywing]

Does anyone know sources that can prove the difference between the 2 types of maintenance, i've found information on oil consumption, staff training procedures and engine monitoring for ETOPS aircraft but have not found information to compare to that of NON ETOPS maintenance. I understand that NON-ETOPS aircraft are not subject to as stringent maintenance in these areas but i don't have sources to back up my claims.

Thanks
