Hi, whats correct oil level on dipstick and when do you check hot or cold??i did oil change yesterday, i drained old oil, and put in 4.5 litres , when the cars cold the level is upto the teiwst on dipstick maybe 5mm over top dot. Should i drain some? Like literally loosen bolt and pull it for 1-2 seconds ? I think that should be enough time to remove 200 ml at least
