I have a 08 and and I noticed some oils burn more than others. I thought I had a problem but tried different oils first before dealing with the dealership headache. Tried about 7 oil brands and the only one that doesn't burn a lot with my driving style and abuse is Motul. So I have been using that for the last 2 years with zero issues.

 

I had a 05 G35 non-rev up. Didn't burn oil but the valve covers leaked. Now have a 08 G37 and I redline at least three times a day and I check my oil frequently. Still haven't seen it go down a drop

 

I know this is an old thread but I have a 2013 sedan (Bought it used in July with 18,000 miles on it and now it has 32,000) and I have to add a quart in between oil changes. I use synthetic oil and was changing my oil every 3,500 milles. I guess I'm going to start changing it at 3,000 miles now.

 

I've never burned oil between the 06 revup, 08 and 09 when they were stock. 06 revup DE started burning a little after I've modded the crap out of it. 08 and 09 HR engine doesn't seem to burn even when modded.

 

20K on my sedan, best I can recall I've had to add about 1/4 qt in about 3200 miles of driving recently, some of it quite aggressively (road trips and twisty backroads). We'll see what I have to add in the next 10K miles.

 

I change my oil at 5K, no issues with needing to add. It does drop slightly, but my last report from Blackstone I was told that I could easily go to 6K without any lubrication issues.

 

I have a '08 with 90k miles, I have used synthetic since 16k miles (when I took ownership) and change the oil between 3500 and 5000 miles .... don't burn/loose a drop!

 

Mines an '08 also and I currently have 86K on it.

 

Google g37 burning oil and yes, some people have issues with it still.

There is even a TSB for it.

My 2010 sedan burns a little less than half a quart every 5k miles, I'm at 66k miles now and have been using pennzoil platinum synthetic and purolator pure one filters since I got it at 30k.

 

Here's a useful pic from the pdf clutchfan posted.



Left column is how low in mm the oil level is from the full mark, horizontal axis is mileage. No good is considered excessive. For 3500 miles since last oil change, 21mm (apprx 13/16") is considered acceptable.

 

Thanks Solo ^^^
Both our Gs (07 & 09) never more than a mm or two below the top mark on the stick, total miles between the two is now about 185k.

 

You're welcome. Just call me Jay. Solo is part of my last name

Impressive with the oil consumption at 185K miles. My consumption above was from a few road trips that involved some sustained revving of the engine (3-5K rpm) on the twisty backroads. I was about 5mm low when I returned from the trip. Similar past road trips had minimal if any oil consumption.

Compared to my old camaro which needed a quart every 300-400 miles, I can live with a pint every 3K

 

Last time I did a oil change I was missing a bit more than 1qt. Same problem I had on my 03 g35

 

I just did an oil change on my '13 X sedan with 7500 miles between changes.

No oil burn. Not surprised because I check it every other gas-up and it hasn't moved more than a mm. I was ready for the burn, but nothing yet. I have 17K on the OD now.
