Oil pressure gauge reading on the highway?

I just purchased a 2006 SR5 Access Cab with 85k. Did I get a good deal, only time will tell. I picked it up from a new car dealer located about 275 miles from home. Just curious but what is your oil pressure gauge supposed to read when on the highway?

 

No idea, how much did you pay for it?

 

Selling price 15600. SR5 Access Cab 4x4 with 85K. Has a color matched topper which I needed, tow package, bedliner, super clean frame and a clean carfax with a great service history.

 

Welcome from LA (Lower Alabama)! Typically, the oil pressure stays around the center, sometimes moving higher when under acceleration.

 

Mine stayed around 1/4 the whole trip moving higher on acceleration. Wondering what might improve the pressure?

 

If your oil levels are fine, then that pressure is ok. As long as it doesn't drop down close to the redline. I was answering your question in general, based on the dozen or so vehicles I have owned in my life.

 

Thank you so much and Roll Tide. I enjoyed everything on your script at the bottom.

 

Welcome from NY.

 

The 4.7s are notorious for this. It's not the pressure, it's the gauge and sending unit. Mine drops to almost zero on warm days at a dead stop.

If you hear knocking, then you should be concerned.

 

Thank you Mr Badwrench. I was hoping someone was going to say something like that. No knocking so far, but then again it's only Day#2.

 

Another characteristic of the 4.7 is some rattling after cold starts. It does sound like a knock, I've heard to it referred to as piston "slap", but many of the high mileage 4.7's do it.

It is not oil starvation/pressure related. At 85k, you probably don't have it yet.

85K miles! You found a unicorn. If you've browsed this site very much, you will see there are countless first gen tundras with 300k+ and still going strong.

Just enjoy your new truck.

 

It is truly a unicorn. I worked at a car dealership my whole adult life and saw plenty of trade ins. I may have seen one or two vehicles in this age range as clean as this one. I'm still pinching myself.

 

Welcome....solid deal if all is as you say, especially a good frame. Taken properly care of, you'll see many more miles !

Speaking of my 2004 only, at 200K miles, mine still follows very closely to what is shown in the FSM....at idle approx 5 psi which is 1st line on gauge from L.
At approx 60 mph/2000RPM, the indicator is pretty much dead center mark. On startup, until engine is warm, it might hover at 3/4 or less. In your case, you might want to consider checking your reading by temporarily installing an oil pressure gauge.

Thank you Bubba. I did read the threads yesterday. I pulled my dipstick, no deposits, no nothing. Oil cap looked the same way.

 

I don't have complete faith in dash board oil pressure gauges. I'm more about the sounds.

 

Change your oil, make sure it's 5W-30.

The 0W's are thinner, and run lower pressures as a result.

If it's not been done, your 4.7 could use a complete timing belt job...

05 Sequoia with the same 4.7 registers the same as yours for over 15 years. Once in a while the gauge drops to no pressure. So I pull over, turn off engine, restart and it usually shows back to normal pressure. Gotten so I just stopped pulling over and it would recover in a few miles, bad sending unit or gauge I suspect.

 

The oil was brand new, never seen cleaner oil. Carfax and tag under hood says timing belt was changed at 61k in 2011. Thanks for the suggestions though.
