2010 Genesis Coupe 3.8 V6 w/105k miles on the engine. Castrol Edge Extended Performance 5w20 for this sample with an OEM oil filter. Every time the engine was warm it saw high RPM operation close to the redline. Plenty of spirited driving ranging from hot to cold environments. Vehicle has aftermarket cold air intake and exhaust with an ECU tune. Manual specs 5w20 for energy (fuel) conservation and up to 5w40 for greater protection during severe operation. I wanted to show that a 5w20 was more than adequate for this engine. Apparently I used the Edge with titanium and didn't realize it, there are no titanium wear components in this type of engine to my knowledge, and no supporting evidence of unusual wear. For comparison, here is the report before this one with standard Mobil 1 5w20 (non-EP version) and an OEM filter.
