**wear metal averages established by Blackstone Labs and based on ~6,400 mile oil change intervals from all similar Hyundai engines**
-10,222 miles on oil and 157,854 miles on engine at sample date
-Mobil 1 5w20 Extended Performance was used with an OEM filter
-engine sees a WOT pull to redline at least once every time it is fully warmed up
-I drive mostly highway miles (~600/wk)
-several hundred miles per month cruising at/near 100mph on Texas toll roads (moderate-high load at moderate-high speed)
-also have a CAI and stage 1 ECU tune
-previous oils on the report are as follows, all 5w20's and an OEM filter with similar driving usage: Castrol Edge Extended Performance (9k run),Pennzoil Ultra Platinum (11k run), Castrol Edge Extended Performance (8.3k run), regular Mobil 1 (6.6k run)
-current fill is Mobil 1 Extended Performance but I am trying a Purolator PureOne filter due to better filtration properties and seeing if it drops the insoluble counts which are consistently around 0.3%. Haven't noticed any additional valvetrain noise due to an aftermarket filter, and yes I am aware of the TSB about them.
Seems to show 5w20 and an OEM filter provides adequate protection, even when you have fun with it at higher miles.
