The 2.3's are looking to be decently easy on oil, the only concern is extended changes and soot loading (timing chain wear) and GDI Valve deposits. Both of those lead me to a 5k OCI for this particular motor. I usually use Havoline LifeLong 5W30 (Syn), but it was hard to get for a bit, so the next few changes will be with Havoline HM 5W30 (SemiSyn). IMO with the 5K changes, anything that meets the Motorcraft (or better) spec should be just fine. I tow pretty heavy with my truck, and don't have any problem using pretty much any oil.
