TSB for oil consumption on the VQ37VHR.

cheshirecat

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.

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.

Does the chances of Nissan replacing your motor due to consumption go away once your warranty is up?

The drivetrain warranty is 5 years/60,000 miles. If it's a recall, Nissan covers it, but not TSB's.

Like CMike mentioned, the TSB is just a Technical Service Bulletin meant to instruct service techs and dealers how to deal with a problem identified on certain makes and models of vehicles.

It's not a recall- the dealership is not required to service your vehicle beyond the stated warranty regardless of whether or not a TSB has been issued, unfortunately.

So to be clear, Nissan is on the hook for the Oil Consumtion TBS during/until the 5 year/60000 mile warranty expires?

Nissan is on the hook for any kind of issue with your engine and transmission (excluding wear and tear items like the clutch) until 5 years/60k miles.

This includes oil consumption. The TSB is just an instruction manual for dealers that is supplied by corporate to help them through the process.

The existence of a TSB doesn't effect your warranty either way. It only helps in the way that Nissan has acknowledged that there is a problem common enough that dealers should be aware of the proper procedures to follow in the event of service visit by the owner that pertains to the problem in question.



.. rather than type all of that, I guess I could have just said "yes"

GaleForce

Thanks. I do appreciate you going above and beyond "yes"

I spoke with my local dealer today. I'm scheduled to start the testing procedure tomorrow. My oil has gone from high to low in approximately 3000 miles. I currently have 10000 miles on the car.

I'm actually pretty impressed by the oil consumption on my '12. It's now been just shy of 3200 miles since I last changed the oil (1290 miles, now 4485 miles). Prepping for a long trip, the oil level was down about 6-7mm from the full mark. Quite acceptable IMO. I topped it off to within 2mm of full. The trip is slightly over 1K miles, so we'll see where it's at when I return.

Ive already had a new block put in... due to OC...wounder if there will be another in my future....
