Normal consumption of oil is considered to be up to a quart per 1000 miles. Anything more than that is probably considered excessive. Your answer will be found in a phone call to Nissan or your dealer. You're going to get all kinds of "opinions" in here. Mine is just one of them.

Unless you have an oil leak due to your cooler, Nissan shouldn't give you a hard time for doing your own oil changes or having the cooler. Neither would explain oil consumption in the absence of leaks. If Nissan did hassle you, I'd suggest you start moving up the chain and call Nissan North America.

if the car burns any oil, theres a problem. Who evers saying its fine for your car to burn oil is wrong and is giving out false information. The car should not burn anything! and if its burning up oil, where do u think its going? its getting by the oil scapper ring and burning up. For example - i put a short block in a g37s under warranty, the car was burning up 1 qrt per 1000-1500 ml's, we changed the motor and now its not consuming ANYTHING, hes been back 5 times and the oil is always at the top of the cross hatchs.

Your so wrong! Go talk to BMW and Audi Owners. I also own a 2008 TT 2.0 FSI Turbo and in the owners guide Audi will tell you this car, can use up to 1quart of oil per 1200 miles if the car is run hard.

My TT goes 10K miles on oli changes and I have to add 1quart of oil every 4500 miles or so.

Also go look at Lamborghini they also burn oil.

The manufacturer is NOT the gospel. They implement those ideas to keep from having to fix their product and loose money. Go out and dump a qt of oil on the ground and then try to explain where that much would go from inside a sealed engine that doesn't leak or smoke in 1k miles. That is not normal and if it were normal, there would not be TSB's to cover oil consumption issues nor would dealerships be allowed to begin the process of oil consumption tests.

Someone asked what the mm chart represented as far as quarts and the answer is 8mm is approximately a touch more than 1/4 of a qt. The amount of space between H ~ L is 30mm, between the hash marks is 24mm.

Most people don't understand that dealerships would love to replace your engine as they get paid by Nissan for warranty work. When I had my engine replaced in my 04 G, I had no problems with getting a replacement block and that year vehicle DID NOT have a TSB to cover oil consumption.

Dealerships and their employee's get paid a lot less for warranty work, and that takes away from money they could be making doing non-warranty work, and if they have too much warranty work, it looks bad to corporate. They are not clamboring to replace your stuff. You just got lucky/found a great dealership that went to bat for you.

VCuomo

You are absolutely correct - the dealer usually makes a lot more profit doing non-warranty work.

Just an update since this is still an active thread, after having my oil consumption issue diagnosed by my Nissan dealer, they replaced the short block (that didn't work) and so they replaced the long block (along with another short block...the entire engine) at 15K. Just passed 20K on my '09 and it's running beautifully!

Seems we still have some confusion around here. Let me try to clarify. the '09s had an oil consumption issue related to the seals not properly setting upon break-in. Oil consumption was in fact oil escape into the exhaust system. Nissan still won't say the volume they measure, I'm sure it's designed that way so you go to the dealer for servicing. There seem to be a lot of folks here that change their own oil and thus have no idea if there consumption rate is normal or if they too have the seal issue. If you are changing your own oil and not servicing with your Nissan dealer than there really isn't anything anybody can really tell you. Your oil consumption is going to be a product of the amount of heat you put your engine through. Where you drive, how you drive and distance/duration are all going to contribute. For some 1 quart per 5K may be fine, for others that track their car the distance will be much less.

Anybody know if they provide a loaner car when replacing the short block?

Totus44

yup...but don't expect a GTR. my dealer had Hertz office in the service dept. so i got a voucher for the rental. they still put a hold on your credit card, but the dealership gets the bill.

btw, since they did the short block and then the had to go back and replace the entire engine, not only do i get a loaner car, nissan north america reimbursed my loan payments (pro rata) for every day in the shop.

nextbesthing

My dealership is telling me they only provide loaner cars for EXTENDED warranty service and not warranty service. They also say that I can rent a car and they can do their best to try and get Nissan USA to reimburse me.

Mine has stopped and apparently I was losing oil bc my oil filter wasn't tight enough. So I really tightened it up and so far so good.

Wow, you didnt have any oil pools in your garage or parking space? I would think that if that were the issue you would have noticed it or the dealer would have noticed it when they took the under cover off to change your oil. Just wondering...

Glad that I found this thread. I changed my oil today and I notice I lost almost 2qts of oil. My last oil change was in October 2010, today is Marh 13, 2011. Yes a lot of months but in Oct I had 16k today I have 19k. So i really used 3k in 5 months. Also I use the car maybe twice every other week. Sometimes 2 weeks without driving it. I read some of u took the car to dealer and they replace the block :O I hope I read wrong.

Any suggestions? I will call the dealer anyways tomorrow but I want to hear from people that really drives a Z not a tech that read it on a book.
