Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
what oil was being used before and what weight oil ? was it full synthetic ?
what weight synthetic oil did you pout in it ?
if your using the correct weight oil which you are can you tell me how long will the knocking sound last ?
what brand filter vs what the dealer is using for an oil filter ? and the oil is full on the engine oil dipstick i am assuming ?
if it was not doing this before the oil change get a dealer oil filter and change the oil filter out with the dealer brand and the oil if 5W30 should be just fine in this engine
if it still makes this noise have the dealer listen with a stethoscope to narrow down the noise area of a bottom end possible bearing causing this noise or a lifter or valve train issue
we have had oil filters cause this kind of issue so its worth a shot to try if the noise is still there then it is very bad timing of an internal engine failure of a bearing or valve train part or lifter
but in a nut shell you did not do anything wrong at all

i agree with you
but if it was not doing it before and you are 100 % sure it was NOT doing this before then its the filter or real bad timing for any kind of engine failure
try the filter and if it still this noisy tow it to the dealer
