TSB for oil consumption on the VQ37VHR.

ZForce

^^In your owners manual it states for the owner to check their own oil levels.

Now if you are having the car regulary maintained by the dealership as in taking it to them when the mfg suggests in the owners manual to change the oil and IF the dealer takes an oil reading before the oil change and notices it low on oil then YES it's their responsibilty to inform you of low oil and they will normally check to see if there are any recalls or TSB's. If they check for a TSB, then they should inform you that the car meets the criteria for them to start the oil consumption test.

I would suggest taking a copy of the TSB with you to the dealer if you have any suspicions of excessive oil consumption. I would also suggest that you check the oil on a regular basis (every two weeks or every 500 miles) and keep a log or on post-it notes.

The car with 347 miles on the engine will consume some oil as the engine is breaking in. The ticking sound, I would be concerned with it and report it to the dealer. It's possible the car did not come out of the factory filled with Nissan's esther oil and the dealer may suggest running esther to see if the ticking sound continues. Note there are alternate oil that have the same additive package in their oils as Nissan's esther oil and at a much lowercost.


I ran Penzoil Platinum (which is synthetic) during my break in and changed the oil several times through out the first 1200 miles.There is allot of assembly lubes in a new engine that need to be cleaned out hence the cheap PP oil and several short run oil changes. There after find a good oil to run and remember a Used Oil Anaylisis is your best friend, they run between $60 and $129 for some peace of mind. Some here have been using Red Line synth oil as their everyday oil to run. I cannot vouch for Red Line with the 370Z, but they did not fare to well on the 350Z VDQE engine. Nuf said there as that statement will probably raise some controversy. The point is that you need to find the best oil with your type of driving as in daily driving, track, spirited driving and your geographical location makes a difference in the oil. Point is, you will never know until you do your own used oil analysis as all cars are not created equal and what works in Johnnies car on the other side of the USA will not have the same results with yours being the type of driving you do and your location.

I said enough, and I am just enjoying my 370Z and really do not want to venture down again on the Oil Consumption Road. I will still subscribe to this thread maybe just to offer some experience with the oil consumption we had with my brothers revup 2006 350Z. His was one of the first to have his engine swapped back in the day. Everyone here is familiar with the longest thread going on My350Z dealing NNA and the infamous oil consumption. I have posted earlier in this thread another link from My350Z on Oil by member "Resolute". Very good reading there if you want to know more on oil.

I have said it before and will again, there should be another new thread opened up by a member here (not from G37) to be able to update the first post from time to time. This threads first post is already outdated showing the TSB for the G37 when the 370Z TSB has been out since June 30, 2010.

Thanks for the responses..... I did have a chance to check my oil yesterday and it was about 3/4 the way up between the low and the high. This is the first time I checked the oil. When I started the car yesterday the ticking noise was not there. However after driving and retuning to the garage (10 mile trip) the ticking noise returned. If the widows are up I cannot hear the noise. I can only hear it with the windows down. It seams to be located on the drivers side. Could this noise possibly be normal? I have an "88" Fiero that has the same ticking noise.

BTW, my original question had nothing to do with who was responsible for checking the oil. I understand this resides with me. I feel that the dealer should share the information about the TSB or a recall (if they exist) when someone purchase a car that could fall within certain date and VIN parameters.

Bheaton1,

as others have said, your car isnprobably still in 'break in' mode. However, continue checking. U said you are 3/4 up (I.e., you used half a quart of oil on <400miles). If this continues after break-in, you may want to take it in.

Having my short block replaced next week :/

How did the block replacement go?

They have to place your car on a "oil consumption list". When you take your car to do the complaint be sure the engine has burned 1/4 oil or more within your last oil change.

Then if that is the case they will monitor every 1,000 miles, if the engine burn 1/4 oil three consecutives times (every 1,000 miles) then they are "supposed" to replaced the engine by the TSB.

At least that is what the TSB for the 350Zs said, I have not read for 370Z 2009 to 2012. GL

The TSB for the 350 basically said the same thing as the 370.

The oil loss is measured in MM by the amount of miles on the car since the last dealer oil change. The engine does not need to fail multiple times.

Japanjay

My car failed today actually. Was 15mm low in the first column on the graph, the 1001-1500 mile range. Passing would have been 9mm or less. The test is six measurements:

1001-1500
1501-2000
2001-2500
2501-3000
3001-3500
3500-3750

Pass the first, goes to the secfond till you pass them all. Test over. Fail the first, test over. Make it to the thrid then fail, test over.

I am actually going back at the 1500-2000 mark to let the senior master tech/ service manager witness the test since he wont be back till this saturday. He is down in Cali doing a nissan multi-day seminar on the new 2013's coming out. Another master tech and a regular tech did the test with me and the warranty manager watching. Pictures were taken. I agreed to go into the next column test range soley based on the fact the 15mm low fails in the next already. Otherwise I would have left the car how it sat till he comes in on friday....

So as of right now I got another 600 or so miles to hit the 2000 mark and take it in for the second measurement. As it sits right after the test I failed the first to columns and didnt reach the milage even needed. I told them I will check the stick every morning till I complete the next 600 miles, but if the oil reaches the lower hump on the stick I will be bringing it in early so as not to damage the motor. They all agreed to that and admitted it has already failed the second column they just wanted to makes sure all managers of the warranty claim, both the warranty manager and service manager are witness to the failure.

It is the first the warranty manager has dealt with in the 4 years she has been there. The service manager when I got the chance to talk with him a bit about it when I got the initial oil change to start the test, said he has dealt with 3-4 of them, all no longer had oil issues after the small block replacement.

The other mater tech, younger guy maybe mid twenties and could tell was a car guy, agreed with the service manager in the fact they have both read about the oil issue and was informed by nissan that it is predominately happening in the 6spds and it is because when doing hard down shifts it creates a very strong vacume and generates alot of blow by. Same issue in the 350's.

My 2011 6MT just passed 5000 miles, its been put on 1500miles since last oil change. and the oil level is down to the middle of the dip stick which means 15mm oil gone.
also, the rpm in neutral is always at 550-600 after warm up.
Does anyone has the same issue?

Your engine will consume oil during the initial break-in. While the "official" break-in numbers are under 2k miles, it's very common for the VQ35/37 to consume a bit of oil up to 7500 miles or so.

I wouldn't worry about it for now. Keep an eye on it. If it's still consuming past 10k, check the chart on the TSB to see if it's at an "acceptable" range or not.

The idle level should be right around 600/650 if the AC is off. As long as you don't notice any bogging or stuttering, I wouldn't worry about it.
