Where Is The Oil Going??
 

Hi all, I know I have seen something on this before, however, I have done a search, and unable to find it. Long story short, I am on a maintence plan w/ my dealership, and they change the oil for free every 3750 miles. My concern is the car now has 7,500 miles on it, and over that course of time, I have had to add 2 quarts before each oil change. I have never owned a car that has required this, and I am wondering if something might be wrong. I drive with purpose every now and again, however, most of the miles logged on the car are highway. Can someone please tell me what is up?? Thanks!

Be Safe!

Is this your first new car? 2 quarts in 7500 miles is nothing to worry about.

Agreed. In some BMWs, you have to put a quart of oil after each long trip :icon14: . One of my friend (sunsational04), took a 500 miles road trip (500 going and 500 coming back) and had to put a quart in when she came back. Many ///M drivers put half to full quart of oil in their BMW every month! So, 2 quarts in 7500 miles isn't too bad IMO.

The 2006 350Z MT has an oil consumption problem. Even a TSB was out, so I hope this is not the case for the 370Z. Nissan should already learned their lesson after replacing a few engines on the 2006s.

There have been more than a few threads on this..Seems to not be an issue except in a few rare circumstances. 2 here (I think) have had motors replaced for consumption of more than a quart per 1000 after Nissan performed a consumption test.... A few also got new motors due to a parts failure and related catatrophic oil loss...

It's certainly not the norm..

Short answer...

It goes out the tailpipe. Its normal.

But too much of it will choke the cat convertor.

No, this is not my first new car, it is actually my 3rd. And no, I have never seen anything like this before. I have a couple friends who have vettes, camaros, mustangs, etc..., and all of them sounded very alarmed when I told them/they saw it. None of them have ever reported such problems. I also asked a shop mechanic in the firehouse to look at it, and he too showed concern about this issue. 2 quarts in 3000 miles is normal? It is not two quarts in 7500 miles, it is 4 quarts in 7500 miles!

You are refering to 350s not 370s, right?

Enjoy!

I don't think 2 quarts in 3,000 miles is normal for a newer car. Most newer cars will never see this much oil burning, esp with only 5 quarts to begin with.

The standard 1 quart per 1,000 miles is usually for older cars with some mileage.

What are you complaining about? Its a great feature. Just keep adding fresh oil and you won't ever have to pay $85 oil changes at the dealer. :D. ;)

2qts in 3K miles sounds excessive. Mine consumed about 1/4 qt in about 1.3K miles.

Alright, so the general feeling that I am getting here is that the engine is consuming a bit more oil than it should.... How do I approach Nissan about this? I tired the first time that this occured, however, the shop rep. said he was going to "write it off as break in"......

I replaced 3/4 Qt at 600 miles. Since then (now at 1200 miles) I have not replaced one drop.

Questions for you, how did you break it in? Did you follow the manufacturer's recommendation and keep it under 4000 rpm for the first 1200 miles? Did you vary your rpm's as much as possible? What oil are you using to replace the oil in the crankcase?

You used a bad word "break in"... :stirthepot:
