370Z oil consumption

cab83_750

I thought I read somewhere that the 2010 engines aren't burning oil. Does anyone know the engine serial number range for the 2010?

My replacement engine is so far so good with acceptable, little consumption. I just want to check if the new one is a 2010.

OK. I am prety thick here. I read my manual and found where the serial number should be. Well, I do not think you can read the serial number of the engine without binoculars (one would need need to lift the car and use mirrrors).

Lifting the hood, so far my replacement engine (on my 09 car) has a serial number of ???6757A. I could not make the first few characters.

Not that this matters much, but Nissan has a history of excessive oil consumption even with the V-8's. I bought a new 2002 Infiniti Q45 and it sucked oil like crazy. Seems it turned out to be a common complaint. They finally replaced the engine at 28,000 miles and there was considerable improvement. But as mentioned by others, that is not a real great experience either...it took several trips to get everything sorted out. Fortunately, my 370Z does not seem to have a major oil issue. I've got the fingers crossed.

You know...tho......as long as there are no other serious problems associated with the excessive oil consumption.........I am not going to worry about it.........Just keep the oil level topped off.......an so what........it dosent really cost that much to buy oil.....

Do you have smog-check in TN? We are just afraid that oil might be clogging the cats and we would fail the test! I wouldn't even tell you how much 2 cats cost!!!! YIKES!

About $300 on this site in the 'parts for sale' section. Frankly, I'd rather replace cats every 20k miles and a quart of oil every 1k than go through an engine swap at a Nissan dealer. The consumption would have to be REALLY excessive to make me go with an engine swap.

Glazed cylinder walls, increased emissions, burned out catalytic converters, reduced power, the list goes on. (that's assuming the problem lies in the piston ring sealing/cylinder wall finish)

It's not acceptable at all.
