I'm right at 101,000. Ive had the serpentine belt replaced and other than that just regular maintenence (oil, coolant, and fuel injector cleanings all right before 100,000). Probably gonna do spark plugs soon but I've just learned that my car in fact is effected by the oil consumption issue. I get knocking/ticking noises due to low oil after around 2k miles after a change/fill

2003 G35 Coupe 6MT
2003 Coupe with 190,xxx this month.
Original owner, running strong. OEM engine. Average mpg 20. Using Mobil 1: 10w 30: notice there's more oil consumption lately. Any suggestions?

231,000 miles here. Bought the car from the PO with 199,000 on the clock.
Car has run like a dream since I bought it. I've even taken it to the local track and raced it. Still gave quite a few cars a run for their money.
Only issues I've had in the year I've owned it are:
- Lower inner control arm bushings going out (replaced with Whiteline bushings)
- AC needing to be evacuated and recharged (PO had the AC replaced, and the shop that did it left all kinds of moisture in the lines)
- Replaced (shot) struts and springs at 225,000 with 350Z Tien S-techs and Stagg SHS struts for the Z.
Other than that, the car runs great. Occasionally, on cold mornings, I'll get a faint tapping in the top end from one of the cylinders (I'm assuming a noisy cam bucket), but it goes away once the car warms up. There's some oil consumption, but that's minimal (maybe 1.5 quarts every 3,000 miles), and I'm pretty positive it's from the faulty seals around the spark plugs on the valve covers, and not worn rings.
