My friend ran his car today to school. After we went home he popped the hood and i didn't see any oil cap on his car. I don't know if this hurts the car or anything but i saw oil on his hood and some spill somewhere else. Is there anything that I should check on the car for him? Oh and we went and bought a new cap from the missing one.

well u don't want any oil all over ur car..........

ok no oil cap.. so buy one and screw it on...

it might mess up your oil pressure

well .. you should just plan an oil change here soon .. since you dont know how much leaked out

oil change buy a new oil cap and screw it on
