Hello Everyone,

Here is a fairly recent TSB for oil consumption on the VQ37VHR.
I have the 8 page PDF but I am not able to upload it. The upload tool will not let me even though it is under the max size requirement. In the meantime:
Edit: Here is a link to the PDF: http://www.infinitig37.com/TSB/1SY30.pdf

Engine oil level is low OR there is unusual engine noise.
ACTION
Use the “Repair Flow Chart” in the Service Procedure on page 2 to determine the complete repair procedures
for a specific vehicle.
CAUTION: If the short engine is replaced as part of this bulletin, please advise the customer to follow
the Owner’s Manual Engine “Break-in Schedule” for the first 1,200 miles including:
• DO NOT RUN THE ENGINE OVER 4,000 RPM.
• DO NOT ACCELERATE AT FULL THROTTLE.
NOTE: Check OBD-II “Engine” Self Diagnosis for any stored DTC codes and use the appropriate Electronic
Service Manual (ESM) to repair any DTC code found stored.

applies to your vehicle.

 

Interesting, thanks for the heads-up.

 

I had consumption on my 06 350z and went through 3 engines .. Thank GOD this engine does not consume and my vin is not on there . Dodged a bullet on this one ...

 

I thought this applied to all of 2008-2009 G37s?

 

What year is your 37?

 

Between the VVEL ticking, ester oil confusion, various other issues, and now oil consumption, it seems like the VQ37VHR has been a disaster.

 

hmm . . . so is this something that MIGHT happen but not always?

 

Haven't heard much about this yet, hopefully we don't hear too much about it.
I found my oil to be about in between the H and L on the dip stick at the time of my current oil change after 6000kms (3750mi)

 

I don't see how our engine has been a disaster. Blowing things way out of proportion.

 

Man, I kind of regret buying my 09 now. First transmission jerky issue, then brake issue, now oil consumption... What will be next?

 

I bought a 2010 sedan end of March.
Took it on a trip of 4,000 miles when the car was only 1-1/2 months old and had 2,000 miles on it. My first oil change was at 6,000 miles. The oil was still at the full mark on the dip stick, at that time, so apparently I don't have an oil consumption problem.
I have had zero problems with the car to date.

 

People are blowing this out of proportion, imo.

 

Agreed, we haven't seen really any issues with oil consumption. My dipstick stays in-between low and high when it's time for my oil change interval. It's not out of the ordinary to see your oil levels not at the full mark being a lot of it sits on the head, and all cars burn some amount of oil.

You would think they would have fully fixed this issue by now with the HR motors, and now the VHR.

This is a great few paragraph article I read;

"Now a word about new cars. People notice the engine in their new vehicle seems to be burning oil. They contact the dealer and are advised that using oil is a "normal condition." I agree, however there is a difference between "burning oil" and "using oil." We just discussed how oil is burned. In contrast, today's engines operate at higher temperatures and compression ratios, causing oil to be used. Higher temperatures and compression ratios achieve two things:

1.

Lower exhaust emissions
2.

More power out of smaller engines

However, along with these benefits comes the side effect of using oil, due to the increased friction and heat. As a result, the oil is evaporating or being broken down while doing its job. In other words, the oil is being used. It is not going out the tail pipe as it does when it is burned.

The rate of oil use depends on how much the vehicle is used and, more importantly, under what load. For instance, a 3/4-ton pickup truck used for hauling will use more oil than a small passenger car. For those experiencing a higher rate of oil use, I suggest using synthetic oil. It has a higher resistance-to-viscosity breakdown and will do a better job than standard oil."

It kind of makes sense though, are cars are using 11:1 compression which is fairly high ratio which causes more oil evaporate.

 

thanks for the TSB!

 

i have an 09 coupe and since mid summer have undergone an "oil consumption test/record" . i would have less than a 1/4 of oil left (dipstick) at 6000km oil change intervals. just got a call today from dealership....new motor on order.

09 g37s coupe mt
35000 kms
used ester oil from day one.
