Oil pressure warning light

Red oil can, often with a drip Stop now. This light means the engine has lost the oil pressure that keeps its moving parts from grinding together, and damage is already happening while it stays lit. Pull over as soon as it is safe, shut the engine off and do not drive on until the cause is fixed. Low oil pressure is not the same as a low oil level, so the light alone does not tell you how much oil is left. Check the dipstick, but do not assume a top-up has solved it: if the level looks fine, or the light comes back after you add oil and restart, call for a tow.
