You should have them do a compression/leakdown check on that motor. Also, if you really are using that much oil, there should be oily residue on your exhaust and/or sparkplugs. Ask to see each plug as they pull them to do the leakdown. A major oil control problem will likely be obvious. Take a camera. You might need it in court. Good luck.

 

So you wouldn't need to add another quart if it's halfway between low and high? I just want to make sure my engine is not burning oil. Sometimes the exhaust pipes get a lil bit of soot buildup around the inside rim.

 

Half way is NORMAL.

And my exhaust also gets soot built up around the tips around the outside of them as well. I am never low on oil and I go 6k between changes.

 

Halfway is probably not normal when 500 miles ago it was at the high mark, if not over...that is the point that we have been trying to make. This clearly shows excessive oil usage.

 

5 quarts is half way on my dipstick.

That is normal. Both of my G35's have always read half way on the dipstick. This is the very reason I change my own oil so I can keep track of it.

Again the dipstick does not clearly show oil usage. YOU MUST MEASURE WHAT COMES OUT CORRECTLY. Also the OIL PRESSURE LIGHT will come on if you have less than 3 quarts left.

EOD.

 

Here straight from the Service Manual.

As I said, half way between L - H is NORMAL.

 

Well, I am a firm believer that arguing over the internet is like winning the Special Olympics, but please let me say.

I agree that a half way reading is a normal reading and is nothing to be concerned about....no contest.

I am concerned because 500 miles ago, I had the oil changed and the reading was a little higher than the top mark. In 500 miles....the level has significantly dropped....even if it is still an acceptable level.

I hear what you are saying about the dipstick reading not being reliable...as stupid of a design as it is, it is hard to believe that it could be reliable. However, the service manager at my dealership has confidence that it is an accurate reading. Not saying anyone is correct....just a difference of opinion.

How do you know about the oil pressure light coming on at less than 3 quarts? I have never heard anyone say that before, and have not read that anywhere.

I know that people here have commented that the person that changed my oil probably didn't get an accurate reading and probably isn't educated enough to know better. However....he lives underneath cars all day and is probably more of an authority on oil changes than any of us here. I am VERY CONFIDENT that he knows the difference between 1 quart of oil and 3 quarts of oil. If the pressure light is programmed to come on at less than 3 quarts, then I believe that my light is defective.

I believe that this is further backed up by the (dealership documented) oil that I have used in 500 miles. These issues combined provide a clear indication that in my first 3000 miles, I had used almost all of my oil.

 

TX you crack me up. First you post->

The you post ->
You can't even let yourself have the last word!
hehe
Let's suffice it to say. YOU are right. Whatever you say. Even if it doesn't accurately represent what has been said by previous posts. You are right. That doesn't matter. You are right d@mn it!

 

Nope, just like having hard facts to back my statements up. So when I got home I posted the SM page.

Yes I am right because the SM IS RIGHT.

 

Yes, you are absolutely right about oil reading at the halfway mark on the dipstick being normal. The problem is that nobody here ever challenged that, so you are kind of arguing with yourself.

The discussion here is the amount of oil being used by the car in such a short time frame!

Thanks

 

LOL that is the discussion the arguement is you can't go by what the dipstick reading is.

 

The oil pump in the VQ will not even pick up oil with one quart in the oil pan.
With the engine running there would be close to two quarts in the oil passages and up in the valve train (windage) You would have to have a minimum of 3 quarts just to keep your oil light off. No way was there one quart left when you did an oil change.
You were just one quart low, that's it.

 

Well, the dealer service department has a lot more confidence in that dipstick reading than you do. They would have everything to gain and nothing to loose by telling me that the dipstick in inaccurate as you are stating.

They are documenting and agreeing that the car is using too much oil. Sorry, but they are the trained technicians. If they felt there was nothing to worry about, I am sure they would not hesitate to say so.

Gee Pasta...no offense, but now the guy who lives under cars and changes oil all day long can't tell the difference between the 1 quart that came out of my car and 4 quarts which would have been there if what you said is true? Sorry, I just can't agree with that.

 

FYI, I have changed oil all my life on all my cars. I have worked on cars all my life more than a kid that just does oil changes. FYI we know usually more about the car than the kid that does oil changes with hardly any experience.

The KID (TECH) does not require any training to do oil changes at dealers. Trust me I have friends that work at dealers that tell me this. They have PORTERS (use to be) do the oil changes as the next step up. They are NOT EXPERIENCED.

And the dipstick on these cars have always known to not be accurate. You can't go by the dipstick and say yea I am 3 quarts low.

And next time you want advice don't back the dealer. You asked us for advice and we are trying to help you but its obvious you don't want it. Gee Pasta, myself and a few others are well experienced with this car and engine.

Gee Pasta is right. And a lot of us have said it as well. There is no possible way your car had 1 quart left. You would hear metal on metal and lots of bad noises with the oil light on. If you keep denying the guy obviously measured what came out of the car wrong and think the car can run on one quart of oil, then you need to grab a service manual and do more studying.

Did you see the guy drain the oil? Did you see him measure it? They USUALLY do not have the means of a device to measure the oil that comes out. He guessed what it was probably by seeing it flow out. They have a big pan that it goes into (a 55 gallon container usually) and it can not be measured.

 

Is the engine still consuming oil?

Note that when you drain an engine of oil, there is still a fair bit of oil around the engine. "Most" of it goes to the sump/oil-pan, but not all of it. So even if only 1-2qrts came out you could have still had an additional 1+ in the car. The dip stick isn't a perfect way to measure oil, but it gets the job done. The car has a pretty wide margin of acceptable oil levels, so having an inaccurate measure device doesnt matter too much.

You can put too much engine in a car, that excess will get burned off. That is normal, it will leak until it equilibrates itself.

If the car is still consuming oil, I hope Infiniti takes car of you.
