Couldn't hardly see the oil level in the thin window on 5L Castrol Edge 0W40 bottle, and accidentally overfilled by 3/4 quart. That's 7-3/4 quarts in a system that normally says full with 7 quarts. I did drain it quite thoroughly and let it sit with the drain plug out for several hours. The oil level monitoring system doesn't indicate overfull, but I don't know if it would. Not real worried that that amount of overfill would be enough to cause a problem in a sump with that large of capacity. Would monitor system indicate over full? Should I drain some out?
