I wasnt shure which section i should post on so sorry if its the wrong section. I have a 2004 Honda Civic Lx Automatic and have driven 40,000 miles (hard miles). I have done oil change every 3000 miles and rotated the tires (actually changing them now for the second time), changed the interior filter and put a cold air intake on ( dont have to change the engine filter that way). question is should i do anything else as far as maintance like changing the fluids andy other filters. I am probably going to change the spark plugs at 50,000 Miles. Any suggestions would be appreciated.
