Hyundai 1.8gdi hybrid engine recommend oil is 5w-20 and to change it at 7,500mi which is a fantasy.
There appears to be a little dirt or sludge around the bottom of the filter.
Since I use PP and 6,600 miles and 13 months is the longest oil change by far fo time and miles.
Usually I'm doing 3,500 to 6,000 miles and 8 months max I doubt it's sludge. More likely dirt as it has an air filter made from what appears to be used dryer sheets.
For 6,600 miles it appears to have done well, no need to go bigger.
