Well, my S seem to lose oil faster than normal. For example, filled about five litter of oil into my car 4000 miles ago, now i just check it there is only about 2.5 litter of old oil left. is this normal?? thanks

 

have you been vtecing a lot?
the more you vtec, the more oil is consumed

 

No, i rarely get into vtec even though i love it.
