Quick question for people in the know- what should oil pressure settle at in psi when it's warmed up?

Hi @jvanzyl
Around 20psi - Have a look at Carolyn's post in How To / Install Oil Pressure Gauge (Nov 2016) - some interesting advice/comments/observations there.

Does the gauge have a warning or light under a certain pressure? 

Not really applicable to us daily drivers but just wondering

No it's a gauge. (wink).  You have an idiot light in you instrument cluster.

The actual when-warm pressures can vary a little with the type of oil. I noticed warm cruising pressure varied from 60psi to nearer 80, when I changed to a 'sport' oil.  You'll get used to how yours behaves quickly, so you'll know when it's properly warmed up.

Isn't thr idiot light the "boom" light? I.e. Too late now, damage done?

The idiot light is basially only for startup.

Theoretically* the warning light can save the day in case you crack the sump and dump the oil. In that case heeding the warning light can save the engine.

For the rest the idiot should check the level with the other dipstick.

* not thát theoretical over here; for those living beyond city limits a sheet metal sump guard is a popular mod under any car.
I cracked one too when recently arrived here. There was a pothole in the concrete ´vado´just 100 meters down from us. Light lit up just as I parked at the farm. No harm done other than a new sump lid.

An idiot light CAN save the day.  If it starts to 'wink' at you, rather than coming full on - then the oil is low enough to allow the scoop to suck air occasionally.

That is a case of go no further  before adding oil.

If you're honking along and it comes on permanently, then it changes from an idiot light to a 'boom' light.

About that, what happened to simply replacing the switch with a sender?
I still have a old Veglia from an Alfa in the garage. The sender goes in place of the switch and the dial has an inbuilt light.
If you want(ed) to retain the original light, then you fitted a simple junction/t-piece depending on the availeble space.

Have you seen where the pressure switch is on a 1ZZ?  That's why we go for sandwich plates.

No, did not look for it, but ah!! availeble space.

Horrible solution though, but alas, no option then.

So some interesting learnings from todays first drive.

• Liking the fact that I've done an oil change - must get better at doing it on time
• It literally took about 20 mins of casual driving before I hit the 25 PSI mark on idle - I've totally been going heavy on the engine too early.
• If you go through very deep puddles with the vent on at your feet, your feel will get a bit of a splash!
• Licence plate sticky stuff is on order to arrive soon.. the sticky pads that came with it gave up towards the end of the journey
• Middle of the dash placement is okish.. the problem is that it can get reflection on the windscreen despite having the "hood" on it.. might need to move it to the right or much further forward.

All in all a worth while exercise!

Oil temperature gauge would of been more useful than pressure to be honest, its good to have both but to me temp is most useful especially this time of year.

Pressure you cant do much with apart from spot a worn engine whereas temperature you can see when its ready for thrashing...or time to back it off if been thrashing it too much

Next project for you get Oil temp gauge to go alongside your pressure

Also to add why did you go 10w40 ?   in cold weather espeically you would be better off with the recommend 5w30

I know you track you car, so oil temp is important to you.  However, a pressure gauge also tells you when the oil is warmed up.

So, for a road car, I have to say I disagree with you.

Re temp - I was under the understanding that the oil would be up to temperature when the pressure dropped to the 20 ish mark so surely it's a rough equivalent to show that it's up to temp? Totally up for getting enough gauges so that I can get a triple cluster going just for fun really.

Went for 10w40 because it's what I had in stock, I had 10L sat waiting to go into the Audi and didn't up using it as I had the garage do it.. I do a fair bit of mileage so I'll get through it soon enough.

I cant see how you can disagree that oil temp gauge is far better way of knowing what your oil temp is?    , pressure gauge doesnt tell you when its warmed up it just tells you the pressure, im guessing your referring to fact you get lower oil pressure at idle once its warmed up but how do you know at what temp does it do this without comparing it against a temperature gauge? or that some other factor isnt causing the pressure drop maybe.

I get what your saying but to me oil temp is more critical on road car than pressure gauge so you can see when its ready for some fun, on a track car even more so but also to make sure its not getting too hot.  Oil pressure is useful but less so imo.
My daily bmw 130i has oil temp gauge from factory and it always amazes me how long it takes to start moving from the 70c starting point on gauge especially this time of year.

Yes kind of but how do you know its not something else causing it ?  its a guide yes and better than nothing but seeing the actually temperature is more useful in my opinion.
  Also ive tried a few of the cheaper gauges in past and found accuracy a bit questionable, fitting a good quality gauge/sensor like a SPa design etc is what i do now after getting some scares about low oil pressure which turned out to be the gauge accuracy, they do a nice dual gauge with pressure and temp on one display, bloody pricey though!

Both Smith and Racetech have a neat simple dual one.
I´d like one.

You have to trust it's ok I guess! At the end of the day I fitted it so that I could understand the timing of my commute and where it would actually be warm enough to give it a good rev. I'm unlikely to be paying close enough attention to notice the sudden drop and back off as I'm concentrating on driving, it's a rough indicator that tells me when conditions (irrespective of outside temp) are right for higher revving... that's honestly it.

It's all gimmicky anywya. Fun gimmicky. Unless you track it in which case it's a drop in the ocean of changes to the car. 

I like to rev the nuts off it so I'd use a temp and pressure gauge to make sure the engine is ready for it. 
But having said that, I've been doing that since 2013 and still got a happy engine

Indeed its better than nothing and a good project as it was oil temp during warm up you were interested in why didnt you fit an oil temp gauge ?

Oil pressure gauge is like you say not something you watch all the time and chances are if you loose oil pressure you wont have enough warning to do anything about it, oil temp however you can keep glancing at it during warm up until you see 70c+ then your good to start using the revs and having fun, also if having a reall hard blast or going on track you can see if its getting too hot hence being far more useful gauge to have imo, but its all good fun

I did a fair bit of testing on my old evo2 trackcar in relation to oil temps and pressures with different oils, it was quite interesting to monitor the differences and reason i was doing it was on that car it had design issues on crank thrust washers and good oil pressure at idle was vital to stop crankwalk and excessive endfloat, i was able to get around 5psi more with my oil of choice which was Fuchs Titan Pro at the time.

Thanks, I looked at their listings and the same one is not listed.
