Oil consumption. I have a 2006 350z with 22k miles on and at my last oil change I noticed about 1. 5 quart oil consumption in less than 3000 miles. I tried regular and synthetic oil and seems to be the same issue. Engine is making a funny noise always. Noise is like lifter -type sound. It goes off after 4000 rpms and get worst when driving up hill.
