I have a 2003 350z touring 6mt w/60k. The other day when I checked my oil it was very low. Since then I topped it off and checked it yestrerday after driving 250 miles, the level dropped about halfway between the H and L marks on the dipstick added about a quart and brought it back up. Im concerend and not sure where the oil could be going. I have no leaks around the oil pan head or anywhere else and no smoke while driving. Any help is much appreciated

 

i just recently had the same problem in my 03 as well on 60k on it. Is your oil clean? if it is not your prob sludging up. If so i would get another oil change ( no need for synthetic ) to clean your old oil out. I just did this time to mine (so far so good) frequently check your oil to make sure is not getting low. best to look btwn 500-1000. Hopefully this may help! I have heard that these engines tend to do this as i have read in many forums. good luck
