2008 Sonata 2.4L vs Sonata 2010 2.4L Synthetic Oil Now Recommended

04-18-2022, 03:59 PM
Just upgraded from a 2008 Sonata GLS with a 2.4L to a Sonata GLS 2010 2.4L. I noticed that the owner's manual now recommends synthetic oil.
Is this due to engine changes, upgrades, horsepower or some other reason? The engines seem very similar.
