Low oil Pressure light after Oil Change

Welcome to PC!

I have never had that happen on any car, so I’d be concerned. I can imagine a brief flicker if you didn’t fill the oil filter (if your Prime is new enough to have a spin-on). Double check the oil level and triple check for leaks. That light should never come on except during the lamp test when you start the car.

If you’re actually referring to the 2011 in your profile, then you ought to click on the “report” button under your signature line and ask a moderator to move it to the Gen 3 maintenance forum.

 

This indicates low oil level. Have you checked your dipstick since filling your oil? When the light comes on briefly, it's probably during a turning maneuver that sloshes the oil away from center, causing the light, then when back on straight driving, the oil centers in the pan and the light goes out.

 

Say What????

I believe the light is Low Oil Pressure. Which means stop the engine now or ruin it.

When in doubt--- RTFM.

 

Standby, Houston...

 

Glad you figured it out. Good learning experience.

 

I thought about mentioning the o-ring but you said there were no leaks. The Toyota filters now come with one side of the box covered with an illustration of where to put the o-ring.

If it was just a brief flash, you should be OK. As long as pressure comes back and oil gets to where it needs to go before you have metal to metal, it'll be OK, but that's a really brief window -- I'd say less than one second depending on rpm and engine load. After that, the wear begins and increases rapidly.
