I used to be all about Full SAPS oils. However, for modern engines, it's not really needed or even desired. For example, the 5.7 HEMI runs really well with Mobil 1 FS 0W-40, and it's quieter than with 5W-20. The lifter bleed issue isn't as pronounced either with 0W-40. Then again, the 5.7 HEMI is kind of a crappy engine, and the biggest contributor to the valve train noise in that engine is actually the tiny oil filter that RAM specs, not the oil viscosity. I use the bigger filter used on Hellcats and SRT vehicles. However, my 2.4L Santa FE runs better with 5W-30 than it did with 0W-40. The fuel mileage improvement is tangible, and the motor is much more rev-happy.
Your 2.5L Turbo has an internal oil cooler and a heat exchanger, and the turbo is water-cooled (well, coolant-cooled). If you really want a mostly PAO oil easily available anywhere then I would go for Castrol EDGE 0W-40. You will lose some MPG though. However, Amsoil SS 0W-30 is an awesome oil, and Amsoil released it in the 90s I believe, so they had plenty of time to finetune it. I would definitively not use an HM oil in a brand new high-tech engine like that, and definitively not 10W-30. Just my two cents.
