I've been looking into what a good oil for my Kona N is.
The manual just specs 0w30 API SN+/SP or ILSAC GF-6 which pretty much anything meets.
I came from mazdaspeed3's a while ago, and it was pretty common to use a Dexos1gen2 (current at the time) oil for LSPI prevention. Then I got into boosted coyotes, and people liked A3/B4 oils. The argument was API SP had a degree of LSPI protection, but the shear and wear protection were much better with the A3/B4.
The only oil I see regularly in 0w30 is Mobil 1 AFE. The most recent UOA I saw was triple action. It had low calcium and sodium (typically a good thing regarding LSPI) and ok zinc. The cSt was 9.76 @ 100, which was higher than a lot of 5w30 analysis I poked through.
Valvoline Extended 5w30 looked decent in the UOA as well, calcium around 1500 (bit higher than desired) but moly at 300 and zinc at 940 (good showing). The cSt was 9. The shear on valvoline site was 3.2. I can't find that number for the 0w30 AFE. From memory, RP 5w30 UOA is pretty similar to that, but less moly.
So the AFE seems good since it's the mfgr weight and D1G3. The Valvoline looks good because of the zinc/moly and it's still D1G3
The car sees all kinds of uses. Spirited drives, random WOT pulls, some short trips. I live in the mountains of AZ so can see decently cold mornings (20*F isn't uncommon), and hot in the summer (up to 90 on the mountain, >100 when if in phx/tuscon/surrounding areas.
It does appear A3/B4 and Dexos 1 Gen 3 are mutually exclusive to each other. I don't know enough about the testing protocols to know if A3/B4 has any degree of LSPI prevention (says formulated for direct injection) or how API SP stacks up to D1G3 (I've read it doesn't, D1G3 is much more strict).
Thanks for any input
