Red oil light indicating low pressure? Check the electrical connection to your oil psi switch/sender. If all seems well... I would encourage you to take it to your normal service station and have them inspect your vehicle if your tool arsenal is limited best of wishes. That way you can find out if malfunction is electrical or mechanical.
