Throw the DI fuel dilution into that mix, and it becomes even more incentive to NOT use the specced 5W-20 (but the 5W-30 IS 'allowed' in the two following year's U.S. manuals for this same exact car
) , especially in the summer.
I am going to use what most on here will label an 'overly thick' oil for this engine this summer, a 5W-30 with a 3.7 HTHSV, about a FULL point higher, or more, than most of the 5W-20's HTHSVs on the market.
I will accept the slight MPG, and even slighter power 'hit' in order to get this (Ravenol REP 5W-30) oil's other benefits for the summer OCI (GREAT base stock, LOW NOACK, stout add pack, and low SA).
