I'm probably unnecessarily torturing myself. I originally started considering different oils in the fall to address timing chain rattle at startup but my obsession has since (probably) gotten excessive, while the rattle has remained unchanged. I really like using the Motul 8100 line of oils. I use 3 different varieties right now in various cars maintain, it's readily available and as far as I'm concerned a descent price. The car in question is a 2013 Hyundai Santa fe with the 3.3L Lambda II engine, 10.4:1 compression naturally aspirated. I use regular 87 octane from major suppliers only. My current fill is Motul 8100 XCESS 5w-40. I'm happy with the specs of the oil although going by VOA's I've found, Motul doesn't utilize any Molybdenum in this oil, and CA is high at 2350. I'm considering going back to their xclean efe 5w-30, just waiting on the VOA to return, however I still expect the calcium to be in the mid 1000's or better. I have looked into what the current model year santa fe with the 3.3L specs from Hyundai and they still only call for an API SN oil. I understand most LSPI events occur in the small displacement boosted engines. Obviously they're not concerned with this engine having LSPI events. Should I be?
