thanx for your input guys!
started up my car this morning and the oil pressure was up to bloody 6. then it drops back to around 3. Then during hot times in the afternoon after ive been driving it, it sits at just above 1. it got me worried coz someone was telling me basically my engine is stuffed and a rebuild is needed. but i dont see any smoke or nothing coming out of the zorst, also the engine runs really smoothly without any miss firing or undue noise. so i guess its all right then.
getting the car checked out next week, so ill know for sure. at the mean time, i was told 1 bar is the low end of ok zone, as long as the oil pressure light is not on. again, as someone said, it could be the sensor or gauge, or even bad oil.
any way, ill let u guys know. cheers!
