We’re picking up a 2024 Kia Carnival next week with the dual-injection Smartstream V6, and wondering which 0w20 to go with. Ideally I’d like to go with one with the highest HTHS. The manual isn’t overly specific, other than recommending 0w20 that meets API SN+/SP. No other manufacturer-specific standards to meet. Some of the euro oils meet API SP while also meeting more stringent tests like Porsche C20 and ACEA C6, like Mobil 1 ESP X2 0w20. Not sure on the HTHS on oils like this, as my euro oil knowledge is more the A3/B4 variety like I use in our TGDI Explorer.
