First, don’t do the oil change when the engine is red-hot. Let it sit for half an hour or an hour before starting your work. The oil will still be warm enough to flow easily, but the exhaust manifold won’t be glowing red and 800 degrees. … TOM: Or just change the oil when the engine is cold.
Can you add oil while engine is running?
NO! Don’t fill while the engine is running! Hot oil can splatter out or something foreign could fall in while it’s running. Oil should be added when a car isn’t running and is on a flat surface.
