That's what my first ex-wife used to always say.

Yes, because sludge is building up inside your engine. My wife's 2011 370Z died at the side of the road after 21,000 kilometres (NOT miles, kilometres). Nissan refused to repair it because I had the audacity to have the service done at my buddy's shop. It's a leased car. They want over $12,000 for a new motor. I had it disassembled. Here's what the pistons look like.

Oil Consumption on a New Z
 

I've been using the NEO since the car was delivered and did early oil changes at 700 and 2300 miles with the Fram Ultra synthetic filter. I observed no signs of metal particles in the oil either time when it was changed. I have done a careful and gentle break in over the 1st 2K miles, with RPMs below 4K and no hard acceleration. The engine is smooth and quiet and seems to be running quite well.

I have just put 1100 miles on the engine since my last oil change at 2300 miles and the oil consumed was exactly 1/2 cup(4 oz). This works out to about 1 quart every 8800 miles, so I am very impressed. I've had some old clunkers that consumed almost as much oil as gas and so I'm very happy with this engine. Is this normal or typical for this engine or did I just maybe get lucky with an engine that was made with tight tolerances?

I have never heard of NEO oil until very recently. It is a very small company in Socal. I think they also offer transmission and differential fluids.

How is NEO compared to Mobil-1 and the like?

I think he means Nissan Ester Oil?
