Nissan Ester Oil

When an abnormally high concentration of a particular metal was detected, say Pb (lead), a vibration analysis may be recommended on the component the oil sample was taken from. However, not once was it recommended to change the brand of oil but rather just change the oil and perform the trouble shooting e.g vibration analysis. So, be warned that changing to a different brand of oil most likely will not fix the problem. You will need to diagnose the cause and make the repair.
