My 2003 Sequoia stays mostly at the 1/4 mark. Rarely above 1/2 mark, but never at 0 mark.

I use 0-30 synthetic oil or 5-30. And the oil pressure is typically a little below the half mark when accelerating and a little lower at 60 with cruise control on. But it hovers around the half way mark.

I’ve questioned it myself. Just got my 2003 Sequoia. Changed the oil with 5w-30 Maxlife 5qts. And the last 2 did Mobil Delvac 15w-40 because its what i use in my dirtbike. Been using the Delvac for years as a top off or need an extra qt to do my oil change. My pressure is 3/4 when i first start it and after running down the road for 15 mins or so im at the half way mark. At the 1/4 mark at idle when warm. Like i said this is a know issue but have also read if it shows pressure just keep driving it.

i have a 2005 sequoia and the oil gauge stays at 1/4 mark, moves slightly above under hard acceleration. 229k miles

I was brought up using a tractor on the farm using a 1952 Ford 8N.
When you give it gas the oil pressure goes up and still does every time I start it up.
I still have the tractor. It's almost 60 years old, still 6V and starts as soon as you turn the key and push the button.
Will a new oil sending unit show better pressure?

Thanks

Had similar issue in my 2002. It gradually read lower over the years. Initially replaced the sending unit but that did not resolve the issue. Then the some of the warning lights quit lighting up on start at which time replaced the entire instrument cluster. That solved the low oil reading as well. It reads lower at 50 mph and below but at 60 mph and above reads 1/2 way up the gauge now. New sending unit is certainly less expensive to try first. If nothing else is odd, agree that the cost of a whole new /rebuilt gauge cluster is a little steep.

Mine makes it to halfway at about 75 or hard acceleration, rest of its life it's at 1/4 mark

The only way to know for sure would be to hook up a mechanical gauge and check it. Mine generally hovers around the 1/4 mark as well. I have no idea what kind of PSI that translates to - I miss the days when they put actual numbers on the gauges - like, what's the point? Might as well be an idiot light. I figure if I am showing oil pressure, and the engine is not making any unsavory sounds, I should be fine.

My experience mirrors the others here. Oil pressure hovers at 1/4 on the gauge at idle and then increases with engine RPM. It has never exceeded 1/2 on the gauge though.

Mine will go up to 3/4 for a few moments after start up. Otherwise, it runs around 1/4 at idle and close to 1/2 when on throttle. My buddy likes to put lucas oil stabilizer in with his oil change. He says he saw a difference on the gauge after starting that. He started doing it at around 450k and now he's at 500k miles.

Idles just under 1/2... cold goes to just above 1/2... hard accel shows the same. Never goes much below 1/2 though. 181K on the clock.
