Hey guys, I just recently purchased a 2008 nissan 350z with 60k miles from a Toyota/Scion dealership, and I took it to a mechanic before I purchased it, and the mechanic said it looked clean and drove well....DOH! Unfortunately I noticed that the oil pressure drops to about 9-10 psi at idle after warm up. It just doesn't seem right...and it's only been a little over a week. It's generally 5-20 psi lower than the reccomended psi at every rpm level. I don't have any oil lights or check engine lights coming on and everything seems pretty sound other than this issue (it's really been bugging me). Also, it has a fresh oil and oil filter change and the oil is certainly not low.

Anyways, the good news is that I have a 60 day warranty and it has only been a week, and I also have documented evidence from a mechanic I took it to that it read 9-10 psi at idle and lower than recommended at 2000 and 3000 rpms as well (My gauge is reading correctly, so take that out of the equation). What do you guys recommend I do here? Is this sufficient enough to make a claim and get something fixed here? I'm kind of afraid that they will somehow f me over....Sorry, I'm just a little stressed and need some advice!

Thanks guys!

 

Could be the Oil pressure sensor

 

at idle mine hovers right above the lowest line, always has (also an HR). i havent had any issues in the two and years i have had it

 

Okay, another problem I have is when I push the clutch in on start up (especially on cold days) the engine revs like 300-400 rpms up. Does that happen to your too? After it warms up its fine

 

like it revs high for a min and then drops back down.... if so yes mine does that also

 

Typical behavior, you're scaring yourself into thinking there is a problem.

 

I know it's probably nothing mainly I'm worried about low oil pressures because I heard it can mean some bad things....

 

Did you check the oil level?
I've found oil PSI @idle is much lower in 350Z's than other cars I've owned.

 

Oil level is good, what are you lookin at?

 

What do you mean "what am I looking at?"

 

As in what is YOUR oil psi at idle, haha.

 

Oh haha...

I don't remember the exact numbers, mine is put away for the winter. If I remember correctly, it's 10-15 at a warm idle.

 

Ah okay, this is good news hah
