The last 2 times I've changed the oil in my Civic, I've gotten above the full mark. This last week, it was between 1/2 and a full inch over. It is probably a bit less than the distance between the add and full marks, which is about a quart. I've checked just after driving the car 2-3 times, and no bubbles, so I think I might just leave it in. But it is irritating. I've started changing my own oil since I joined BITOG, and I've done each car several times. It has always been right at the full mark, when I'm done. I'm not sure what the issue is. Logic tells me either I"m pouring in too much, or not draining out enough. I double checked that it was in fact 3.8 quarts, and not liters, when I poured the oil in. I poured out enough oil in a new 5 quart jug, to take it down to 3.8 quarts, and then poured all of the remaining oil down the fill hole. I let the oil drain out until the steady stream had stopped, and there was just one drop coming down every few seconds. Screwing the drain plug back in at that point, I realized there was some oil still left, but I was thinking that it would be only a couple of ounces at most. I did change the filter as well, so the oil couldn't be coming from an old filter that remained there. Now as long as it is not foaming up, I guess I would be ok, but if the level on the dipstick is that high, that tells me that I've got a fair amount of dirty oil in the sump, so I'd like to avoid this in the future. Has anyone here found that just waiting till the steady stream stops, isn't long enough for an oil drain?
