I am currently running 10W30 Mobil 1 EP in the same engine, but the advice above seems to have some merit. At present the oil and filter have only 9 running hours on them, but the oil still looks like new.
The EP 10w30 is still going to treat that engine very well, can't really go wrong with any flavor of Mobil 1 10w30 for OPE.
