After searching through the forums for quite some time, I still have a couple of doubts.

Well, I have an 04 with 38k and am having some oil consumption issues. I know it's not so common in the 04. My mechanic said there's nothing wrong in the car. I haven't taken it to the stealership yet because I have some mods in my car that could void my warranty (injen intake, kinetix intake plenum, and an Agency Power exhaust). I have noticed that the oil burns by itself if I put more oil than supposed. Another thing I've noticed is that the oil burns only if I step on the gas a lot. I use Mobil1 fully synthetic 10W-30 with the Mobil1 filter. I live in PR and the temperature is always between 80 to 100F. I believe I'm using the correct oil.

Is it normal for the oil to burn a little if I step on the gas very often?

Should I switch to another oil?


Here's my oil pressure



With the A/C on..



I know that in idle I should get around 27psi from what I've read but I've noticed that, with the A/C on, it idles at a little more rpms so I got a little confused.
Is my oil pressure ok?

Thanks in advance!

 

Dude its normal, rpms pick up because of the increased electrical usage.

 

the oil pressure gauge has nothing to do with the amount of oil in your car, that only registers how much is being flowed through the engine depending on engine rpm, plus it is working correctly.

you said you are putting more in that is needed. stop. you are overfilling it and that can lead to problems like you are describing.

and finally, none of those mods you listed can void a warranty.

 

keep overfilling the oil and your going to blow seals. 10w-30 may be a little heavy for your weather conditions try a 5w-30 or even a 5w-40. im not too sure but if you have the new style dipstick out front its easy to check the oil so check your oil about every 2 days or so depending on how your driving the Z, and only add if it's needed. (side dipstick suuuuuuux) bout 5qts even it should take. keep the oil changed about every 3 and you should be fine, but keep a good eye on whats going on and make decisions from there.
good luck!

 

Where did you pull that little factoid from? How hot does it have to be for 10W-30? LOL.

I think the OP could try a heavier weight oil without issue. It's only the last number that's important at operating temperature.



As you can see, the OP has no reason to be running a 5W oil. He could run 20W-50 since he never sees cold temperatures. He may minimize blow by with the heavier weight oil.

 

Hey! I'm not overfilling it! It was just one time that I put a little more than supposed (about 1/4" over High). Anyways, I always fill it up to High and it kinda burns a little and stays just in the middle between Low and high.

I have to put in 1/2 a quart every month.

 

I was using 5W-30 and switched to 10W-30.

5W-30 burned a looooooot more!

 

again, if you are filling it to the high mark, you are over filling it. also the proper level should be between H and L (straight from the owner's manual)

so it is not the type of oil you are using or burning oil, just operator error.

 

use heavier oils when you have higher miles is all im saying.
Use w/e you want then, who am i to deny the temp chart?

 

A motor, any motor, with 38,000 miles should not burn oil.

 

I always keep it where it should be. All of this started about 6 months ago when I changed the oil and, after draining all of the oil from the car, there were only 3 quarts out of the car instead of 5. Yes, it is burning some oil and it is not an operator error. I know i've filled it up to H but not any higher. It shouldn't be THAT bad...

 

unless you or the previous owner beat the living sheeeeit out of the car!

 

I bought the car brand new 0 miles! I've never beat the sheeeit out of my car. Yes, I step on the gas every day but never take it to the red line. I always shift at no higher than 6k.

 

um, take it to the dealer?

 

no car comes with 0 miles on it. unless they rolled it right from the factory directly into your driveway

 

3 quarts? did you count for the oil in the oil filter as well in that 3 quarts? i know it doesn't hold that much being so small but unless you measured the amount exactly, you are jsut guessing at the amount you drained. plus did you replace the crush washer with a new one? if not that can cause a leak as well. i both cases, i stand by operator error as the cause.

 

I put the old oil in the same quarts that I empty and i only got to fill up three of them. Yes, the oil in the filter was counted.

 

I picked up the car at the warehouse for that purpose. I just don't trust anyone driving the car that i'm going to buy, especially in the break-in period. Yes, it had 0 miles.

 

In Puerto Rico they come right off the boat from Japan and if he lives near old san juan then it's very possible. compared to Elizabeth NJ. when they come to the port in NJ they have people drive them off the boat and they have to drive to different lots in a few mile radius and so on etc.... IN PR they come off the boat to a trailer.. My buddy works in the port and actually drove a brand new Auto Z last week in the yards....

 

wow, that is really "accurate" measuring you did there. as for the car being driven, how do you think they got it out of the plant to the holding yard, then to the boat? it was driven.

but that is not the issue here. the issue is that you think there is something is wrong with yoru oil, but everythign you have described has been nothing but operator error (proper checking of level, thinking the oil pressure gauge has something to do with oil level, and your measurement of the oil that came out plus your stating of over filling it because you "thought" it was low when it was readign in the normal range). if you are that worried about it take it to a authorized nissan service department and let them work on it because obvioulsy you have no clue what you are doing.
