- just checked and it was millers nanodrive 10/50 used last service too so same oil according to history.

Same I think as car new to me but think it was running millers 10/50 before but would need to check paperwork again..
Replace but maybe i'm mistaken and am comparing apples

Just a bit concerned as could have sworn it ran cooler before I had the oil changed but maybe I'm mistaken and am comparing apples with oranges as different circumstances?

Just got my 996.1 c2 back from service / oil change and noticed the car seems to be running a little hotter than it did before at full operating temp (see pics):
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi all
Just got my 996.1 c2 back from service / oil change and noticed the car seems to be running a little hotter than it did before at full operating temp (see pics):
Before (didn't move above 80)
After (fluctuates between just above 80 and half way between these markers)
It's fitted with a low temp thermostat
I decided to use millers nanodrive 10/50 oil.
Before the service I never saw the needle move above 80 (as per pic)
I've checked and the fans are kicking in.
Any ideas as to why it might me displaying a slightly higher temp on the gauge now ??
Only other point to note is that I was always running with ac on (to help with idle speed) as I had a small hole on oil filler tube that was also fixed as part of the service so this increase in temp was noticed with the ac off.
Maybe running with ac on was masking the slightly higher operating temp ??
Any thoughts people
:dont know:
Thanks
Same I think as car new to me but think it was running millers 10/50 before but would need to check paperwork again..
I also went for 'millers nanodrive 10/50"
Just popped out for another look and did some measurement via temp gauge on AC unit.
Highest I observed after a good run and on idle (before fans) :
103
Fans then cooled to
89
over time
Out on a run maintained about
85-90ish
..
Does this sound about normal :dont know:
One other thing, can anyone advise when fan on engine lid is active ?
The pressure gauge is not that accurate .. if you truly have low oil pressure then at idle you will get the red light flickering on ..
Its best not to get too fixated on a single gauge , whilst that's easy for me to say as it's not my car its all i can say as a mechanic with one or two years of experience .
Evenin' Adam,
Not sure what Mark (other Mark) put in it last year but I always put 10/50 millers in.
Temp might be a little higher than I remember but not sure. Deffo has an LTT fitted which was brand new a couple of thousand miles ago.
Oil pressure is absolutely fine. Anything over 1bar at hot idle is fine and that gauge is reading about 0.2 bar down. Checked with a mechanical gauge when I had it.
They do vary from 1bar even upto 2bar. Although most cars showing nearer 2bar will actually have an iffy gauge that'll read above zero before the car is even started.
Craig's Hartech rebuilt car sits at 1.2bar after a spanking.
Only worry if the low oil pressure light flashes on the dash. :wink:
(And that's set at 0.6 bar out of interest).
What was the story with the oil filler pipe? Just split? It was fine when I had, so I blame other Mark.
Edited - Demort beat me to it.
sorry !
As i said .. its best not to get too fixated on a single gauge .. the car is not young and they were never that accurate im afraid .. its an indication is the best way i can put it .

DeMort
- thanks for digging out the Fan info.. much appreciated! :thumb:
Hear what you're saying re oil pressure gauge and age of car.
Mark
- evening mate.. thanks for the info re oil pressure gauge. I was a little worried for a mo.. No oil pressure lights flashing on dash
So sounds like what I'm seeing is normal then ?? :dont know:
Just a bit concerned as could have sworn it ran cooler before I had the oil changed but maybe I'm mistaken and am comparing apples with oranges as different circumstances? :dont know:
Re oil filler tube. PPI when I purchased reported a small hole in oil filler tube (possibly caused by rubbing against something on the bay and wearing over time) that could possibly cause air leaks / rough idle etc so decided to get it sorted whilst in for oil change ...
So is the consensus, that I'm worrying over nothing
The temps I've quoted, sound ok?
Just confused what could have caused a possible change in engine temp..
