See:

it does not require grounding of the aircraft pending an engine inspection merely an assessment as whether or not an inspection is needed, which is exactly as the underlined portion of the memo states. Again, it almost seems that you are having a hard time translating english language documents.
Regarding the 150 grade fuel issue, this is discussed here:
