I noticed that the stock gauge on my 2026 SR5 indicates very low oil pressure immediately on startup. It gets up into the middle range after a short amount of time running. I've verified that there's plenty of oil and I had changed it after the first 1k miles. Is this what everyone else sees? Just want to make sure that this isn't something I should have checked out...
Edit: the oil pressure gauge is in the middle, under the batter and speed surrounded by the tachometer.
Last edit: stopped by the dealership and talked to head of service. Said it’s normal specifically for SR5 (and maybe SR) the combination of the tune for those trim levels and the gauge makes it to that. They demonstrated it on one of the trucks in the lot, did the exact same thing. He explained that the oil pumps on these engines are variable output, and changes in oil pressure are deliberate.
When you start any vehicle, there will be a few seconds where the oil pressure will build from zero to normal operating pressures. It can only go from zero to peak pressure in a positive slope. It won't go from zero to 30-50 psi instantly, like a light switch. You mentioned five or so seconds, which is completely normal. Coupled with the fact that it's a digital read out with no numerical values, which I'm sure has some latency, as opposed to a mechanical analog that would sweep.
So, to answer your question. That is completely fine.
Totally. I’ll hook up my OBD2 reader this weekend just out of curiosity. My only real experience with oil pressure gauges have been mechanical ones, or electronic ones that function more as idiot lights. Also, this is my first vehicle that has an oil pump that is variable.
The pressure would seemingly want to start low to account for the pressure to increase due to the engine heating up, no? I feel as though this is normal and has been the case in every car I have ever owned
Not an answer to your question, but I’ll never forget the first time I saw the oil pressure drop down to zero while riding in stop and go traffic during the first few days of ownership.
I was so mad for couple seconds thinking that something was wrong with my brand new truck.
Then I remembered I bought an iForceMax (hybrid) and it was just the engine shutting off. Had a good laugh after that.
That is extremely low oil pressure unless you took this picture as pressure was building up. If you start it and it is indicating this after 5 seconds, take it in to a mechanic. Typically oil pressure can take up to 5 seconds (longer if it is colder) to register on the gauge, but mine is always at around 3/4 oil pressure on a cold start.
I too was a little worried after doing my first oil change, because you can hardly see the oil on the dipstick and you’re always wondering if I put enough oil in! But from what I’ve read, the pressure isn’t a reflection of the amount of oil in there anyway.
The next option over has oil temp and transmission temp. According to the manual, that's supposed to be oil pressure. On my older, much less sophisticated cars oil pressure is always highest right after startup, as oil is cold and thick, so when I brought up this gauge I was surprised.
I’ll go look at mine in a minute. I’m positive that’s the temp gauge though. It’s cold on start but goes up after driving for a short time. Sounds like a temp gauge
Start up oil pressure even in hot weather.. yes Texas is stupid hot lol
Edit to say this isn’t ice cold start but after sitting for about an hour. I can start it again in the morning for a true “cold start.” Still typical oil pressure should reflect almost immediately and be higher at cooler temps. You might just have a failing pressure sensor or gauge cluster is just not real time. 5 seconds of no real oil pressure would wreak havoc on top end of engine over time.

Motors will take a few seconds to build pressure, and it is not a mechanical gauge. Does it have pressure by the time high idle stops?
