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 and prior to that had put 3750 miles on the combination of Valvoline Synthetic Maxlife 0w20 and a Fram Titanium 9688 oil filter. Lots of ticking and rattling noises prior to the change which went away immediately after changing oil. I know that the high pressure fuel pump in the engine is noisy and I know what it sounds like, these noises are somewhat similar but distinctly different.
I started doing 5000 mile intervals at 95,000 miles and the issue was not prominent until after the 100,000 mile mark. Two of my friends that frequently ride in the car noticed and commented about the increase in noise as well without me even asking them. I don't know if a possible cause would be the 0w20 or the buildup of carbon soot in the oil system (this is a very real issue with my car) or something else. If nothing else I will try going back to 5w30 once my current stash of 0w20 runs out. Any thoughts are welcome
