Used on 2012 Hyundai Accent GLS between 105,000 - 113,000 miles. First OCI was Valvoline Synthetic Maxlife 0w20 for 4000 miles, second OCI was three quarts of the same Valvoline and one-half quart of Rotella T6 5w30 Multi Vehicle for 4000 miles.
I have posted in a previous engine noise thread about a known issue in which certain engine noise increases as an oil change interval goes on. This can trigger the P0326 knock sensor. Changing the oil and filter is one way of resolving this issue, if it is not an oil related problem the fuel injectors probably need a product like Royal Purple Max Atomizer run through them.
Just like the last filter I used, upon cutting the current one open the filter it was saturated with black carbon soot. The oil drained from both OCIs was completely black and a bit gritty as well. Of note there was a large accumulation of a gritty black substance at the dome of the can. I took pictures of what it looked like on my index finger and thumb, any thoughts on what this might be if it is not agglomerated carbon soot?

Engine noise increasing during oil change interval?
So I have a 2012 Accent GLS with the GF4D Gamma GDI engine and 109,000 miles. Over the last 20,000 miles I have been shortening my oil change intervals due to an ever increasing amount of engine noise that always develops as time and mileage adds up. For example I changed the oil this morning...
