Sounds about right, what was the temp at ??

 

I think the engine temp was 201. Outside temp was 28. It's back in the garage covered up now.

 

FYI Generally as a mechanics rule of thumb the minimum required is 10 psi per 1000 rpm so assuming idle is somewhere around 750 rpm them 7 and a half pounds will protect your bearings. I would be more concerned what it is at around 6000rpm.

 

Amen to that!

 

oil pressure specification:
minimum 13 psi (90 kpa) @ curb idle.
25-110 psi (170-758 kpa) @ 3000 rpm.

 

Where are these numbers from
Mine is at 35% @85% oil life left
1000 miles on cat
Does this look normal
Thoughts

 

Mine is also at 35 psi at idle

 

Mine was also at 35 psi at idle

What was the solution to this issue did you have new parts ordered did they come in from the dealer or do you have it unfixed at this moment.
Tell us a little bit about it
how many miles was on it when this happened was it higher oil pressure and then as it was less oil the pressure as the oil level went down as well thanks for the info kind of a geek when I comes to the stuff I love info
Thanks
Rob

 

It's still at 35. Haven't drove it for about 2 months. Currently at 720 miles. I didn't realize it was an issue

 

That's normal no issue.

 

At low engine speeds (idle), my pressure is very sensitive to what the actual rpm is, so there is proportionally large psi deltas with small rpm differences. If your car is "idling" even slightly low, you'll see what might seem like a "low" oil pressure, but it's directly proportional to engine rpm, unlike at higher rpm where you're getting into the filter bypass and other things.

Mine drops (momentarily) to 35-40 with the engine at low-idle... and fluctuates around 48-55

As long as it comes up to ~50psi or more at 1000rpm, I think you're inline with everybody else.


And then 55psi (or more) at "normal" driving rpm*.


Mine runs 55-62 at normal rpm and spikes even higher with higher rpm



*I haven't had mine super hot on a hot day to know what pressures would be under those circumstances.

 

Bull
Awesome and thanks
Big help
Cheers

 

Mine chills around 60-65 PSI at interstate cruising and jumps around 70 at WOT.

those specs are from shop manual.
assuming you mean 35 psi @ idle? if so, yes, it is in the normal range.

 

What is the idle at on stock cats
What numbers are you guys n gals r seeing
I have 800 in D.

 

Bull
Great post
Thanks for the pics
I actually went back to Valvoline and the guys checked under the car again for me and 400 Miles since I went to the dealer there is now no residue on oil filer or lines
They dealer may have tightened something on Friday when I went in, they definitely wiped the area down though.
Today no oil leaking/seaping
All my temperatures and PSI are the same as yours ". Bull"although mine is at 35 at Idol I think because my RPMs are slightly lower than yours
As you indicated in a previous post the higher the yard the higher the PSI

I've had no real oil loss as of today we check many times the picture I attached says 83% but I thought 83% with how much oil is left apparently it goes by mileage it's just a countdown To the recommended 5k mile oil Change
I could be wrong though please clarify If otherwise.
Cheers
Rob

83% is oil life monitor. the algorithm used to calculate this is duty cycle based. when it reaches 0%, it's time to change the oil.

 

I think it is totally normal, mine also idles ate about 33 to 37 when low speed crusing. I was concerned a lot about it, but after reading this thread, I'm convinced that it is normal.

When looking at the engine oil pressure and temperature, there is a relationship between them as a genral rule of physics. I noticed that this drop in idle oil pressure only occurs while the engine is at operating temperature. Also as oil temperature progresses, the oil pressure drops simultaneously. This actually happens because as the oil gets hotter, it also gets thinner and the viscosity decreases a little. That is the reason why oil pressure can decrease below 50 and 40 psi. Lowest pressure recorded was 33 psi 3 days ago.


I am actually trying to make a simple cooling system to the engine oil cooler to stabilise the temps even when drivibg low speed with higher RPMs, because oil temps go nuts when doing that. Cause by not enough air flow to the oil cooler leading to what we call, " heat soaking".

Hope it helps
Thank u all for ur feedback

I prefer the older style oil cooler setup that is looped into the coolant system. With a 180 therm, it helps both warm up the oil faster as well as keep it cool even at idle.
