I had to top up yesterday, my oil pressure guage started dipping when i brake, i had to almost perform an emergency stop saturday due to some tit pulling out on me, the guage almost hit 0 .. then the oil light came on for two seconds so i thought it would be best for a top up.. whole bottle of oil later and she's fine.
Just curious though, how much oil is recommended once the oil light comes on as the dip stick isnt very good
