Should I interpret this to be that you have driven your SI very hard yet
have not checked or changed the oil in almost 10,000 miles? If you are
frequently hitting "high RPM, full power" then your engine is being used, or
abused, under at least "severe service" conditions.

Read the part of the owners manual about checking the oil and about changing
the oil. That is an expensive engine and you are probably limiting it's
useful life.
