My suv just started making a knocking noise as you increase the gas pedal,it's heard mostly when sitting inside the vehicle.I checked the engine's dip stick and saw no oil then I added 1quart suddenly it was full?? What can this be?
engine on 1999 Isuzu VehiCROSS
use 93 octone gas
Your vehicle is burning oil, has an external oil leak or the oil level was never topped up correctly after the last oil change.
