help, i have just purchased a 1996(n) astra2.0 16v sport, on driving it back a message appeared on the computer display "oil lack"
i pressumed this meant low oil level so i promtly pulled over , left the engine to cool then checked the oil level which was fine(about midway between the markers)
the engine management light also came on but this has since gone off
and the engine sounds perfect
the oil warning light has not come on and oil levels fine
