Just acquired a 2015 Sedona with the GDI 3.3L V6. Was surprised to see in the owners manual that it recommends 5w-30 or 10w-30 in the viscosity chart. I thought all vehicles had transitioned to 5w-20 or thinner a long time ago. It bums me out because I have been picking up 5w-20 and 0w-20 synthetics on clearance (such as the Rotella Gas Truck they were giving away after rebate a few months ago) in anticipation of getting a new vehicle. Not sure I can stomach going down a grade on a newer vehicle with 28k miles.
All my xW-30 oils I have on hand are older stuff that prior to the widespread adoption of GDI, so I think they lack the additive package that prevents against LSPI. Should I be concerned with this in this engine? The owners manual simply states any oil rated ACEA A5 will do, or in the absence of that GF-3 or API SL is acceptable. I believe my older oils meet those ratings but don't have the SN+ and newer Dexos ratings that might offer better protection for DI.
Not sure what to do with my 5w-20 stash as none of my vehicles take it (the Odyssey will be sold soon.) Maybe use it in the cold weather months? I should probably just invest in newer oil for the Kia, rather than use the older stuff that I have. Is this the correct approach? What oils would you recommend for the 3.3L?
