Engine Oil level question

[Ckchong8]

i might have missed your earlier posting. did you mean you had engine knocking problem when the car was using a w20 oil? i have been using Red Line 5w20 for a long time before switching to Castrol 0w30 due to cost issue. i have not encountered any engine issue with either oils.

 

ideally, don't deviate too far from the recommendation provided in the car manual. mine recommends a 5w30 oil, so using a 5w20 or 0w30 oil is still safe.

Probably difference ride bah. Manual recommeded 0w20 to 5w30
