370Z oil consumption

6SPD_FTW

The "normal and acceptable" oil useage I keep hearing is just nothing like I've ever experienced after 3 new vehicles.

First new car was a 2003 Corolla 1.8L 5-spd. Car used 1/2 quart every 5000 miles.

2007 Altima 3.5SE 6-spd. Car used 1 quart during the first 1000 miles and 1/2 quart per 5000 miles afterward.

The 2009 370Z 6-spd is exactly the same. With 19,000 miles on it, this car has used 1 quart during the first 1500 miles, and since then has used 1/2 quart every 5000 miles.

I've always used Castrol Syntec 0W-30 and per Blackstone used oil analysis, the Altima and Z have perfect wear trends. The Z and two previous cars are abused on a regular basis. Lots of redlining, etc. I am smart about it, though and the oil is ALWAYS changed at 5000 mile intervals. Never had a problem.

Strange thing is, I broke the Altima and Corolla in EXACTLY by the book. The Z I have driven like an ******* since I drove it off the lot.
