Guys, I know this topic has been discussed before, but I need more details on when we can till if there is an overfill. Right now, I estimate that I am about 5-7 ounces over capacity. I didn't worry about this because I figured if it's less than 1/2 quart, it shouldn't be a concern. But yesterday, when I shut off the car and checked the dipstick, there was one big bubble on the dipstick. After about two minutes, I pulled the dipstick out again, and no bubbles - everything looked normal. So is it normal to see one or two bubbles IMMEDIATELY after shutting off the car? There was no evidence of "foaming" as there was just that one air bubble. So am I being paranoid or should I drain some out? Thanks.
