I see that synthetic oil is recommended now, but why? Same engine I thought.

I tried searching but I can't figure out how to filter out all the posts about if someone should switch to synthetic, vs if synthetic is factory recommended and why.

Nope just the most current classification of oil...

"Introduced in October 2010 for 2011 and older vehicles, designed to provide improved high temperature deposit protection for pistons, more stringent sludge control, and seal compatibility. API SN with Resource Conserving matches ILSAC GF-5 by combining API SN performance with improved fuel economy, turbocharger protection, emission control system compatibility, and protection of engines operating on ethanol-containing fuels up to E85."
