Oil light when when car is warm

[Toxic#66]

Huston I have problem (Clio2 172 ph1)

Just when the car gets warm oil light starts to light up :/
it lights all the way up to 1500-2000rpm, after that its ok
I checked the oil pressure sensor and to my suprose only one wire goes out from it, don't know if thats normal. I also noticed fresh oil around it

Is it oli pump on the way out, the sensor or maybe something wors ? :/

Get another sensor but sounds like it might be the pump failing.

Good news, oil pressure is still there

at idle 800-900rpm its abour 0,5-0,6bar
according to AutoData target test pressure is 3bar at 3000rpm (mine was 2,8bar)
The conclusion is: ELF SRX 5W30 might be a little to thin for wheater above 28 degrees celsius (as i think of it now it actually started when the weather hit 27 celsiuc)
So i guess its time for semisynthetic oli and since im not used to speed limits oli cooler should help.

What do You think ?

5w30 should be fine in it tbh, first put some 5w40 in it as stated in the handbook. Then change the oil pressure switch if its leaking as it probably leaking out the body of the switch like mine did and thats letting the pressure drop in the switch and putting the light on.
