I use Mobil1 0w20 EP and never go over 4k, the Honda 1.5T is a dilluter, especially if short tripping, ultimately what you're concerned with is viscosity. There is no magic oil, a good oil changed more frequently is a better alternative to frequent UOA's cost considered. A 5W-30 will stay within acceptable viscosity limits a bit longer, and will work well in your engine. I've owned 5 Hondas with this engine, other than changing oil more frequently, they've been excellent vehicles, good mileage and power. BTY, it's a good idea to change CVT fluid every 30k (spill & fill) using only Honda fluid. Honda CVTs are virtually bullet proof if not abused and changed every 30k. Ignore the MM, it's an algorithm based on average use. Proactive maintenance beats reactive every time.
