I would like to share my latest UOA. 7,405 mile interval and 8 month service. The only thing that starting to concern me is the insoluble percentage trending up. Oil filter used is OE Subaru blue can. I guess I'll keep an eye on it on my upcoming interval cycle.
I'm currently running Purolator PureONE oil filter so we'll see if that makes a difference.
