yes flushing oil, better bang gamitin iyon flushing oil then the normal engine oil para malinis, becuase the car soaked in the flood...... just want to make sure malinis iyon loob ng engine ..... para hindi na overhaul...

kasi halos lahat ng mekaniko sinsabi pag nalubog sa flood kailangan overhaul agad.....? it seems need to fully drain the engine ? is that right?

sorry if my post quite confusing....
