My car is a 2004 Buick Park Ave and had it a little over a yr now. Its a non super charged version of the 3.8 motor. I have used AC Delco filter. Other car is daughters and going to change oil next week and its a 2008 Mazda 3 with a 2.0 motor. Since she has had it a garage dome the oil change. What filters should use? Is the AC Delco good for mine or should i tey something else? On it i use Valvoline Restore and Protect. Thanks
