I've got a 2003 LS V6. After draining the oil and replacing the oil filter, judging by the level on the dipstick, my car doesn't seem to want to take 6.9 quarts of oil, per the manual. When you all change your oil, are you checking the dipstick as you get towards the end of filling it? Or do you just add 6.9 quarts? I'd think the correct way would be to check the dipstick and not overfill it, but maybe I'm missing something. Like do I need to start the car to get the new oil into the system? Sorry for the basic ass question but it's been nagging at me.
