Recently noticed that the '04 Chevy Aveo (195k miles) we have in the family is getting more raspy than I remembered when it's idling/pulling out of the driveway. I immediately checked the oil since it was last changed with unknown brand at one of the local $20 places. Oil is at normal levels, and it's never really used much oil.
Any suggestions on what I could try to smooth out the engine a bit?
