Oil Pressure Gauge.

FLA-Titan · 12-22-2004, 07:14 AM

Every morning for the past week, my oil gauge would act almost like a tach. Every time I revved the engine, the oil gauge would move from Low to High along with the RPM's of the engine. It usually lasts for about 10 minutes and then it settles down to normal. I am going to take it into the dealer, but was wondering if the gauges are directly connected to the block or they attached to the ECM module? Also is this happening to any one else?

Mine responds the same way when the oil is not warm. It actually spikes to the H on the gauge. Then after about 10 minutes it settles down to the midway point on the gauge. No big deal, very common...

Several posts have occured on this subject already. A search should bring them up...(and no I'm not a moderator!)

I think Logicjunky is right-- I recall in previous posts that a substancial number of members (including me) experience the same thing.

yeah guys, this is a completely normal thing to experience shortly after startup. the cold weather makes it more noticable because the oil gets thicker when cold. after a few minutes of running, the oil heats up, gets thinner and everything goes back to normal. don't worry about it, it won't harm your engine.

You must be more familiar with ford oil pressure gauges which never move much. They
are actually more like a warning light that is either on or off. Newer Miata's are like
this. Talk about useless. I would rather have a warning light. The Nissan Titan oil pressure gauge is a real gauge and will move wildly around depending on RPM temperature of the oil and a lot of other things. An oil pressure gauge can tell you when you oil is warmed up or if you have a oil pump going bad or just general wear
and tear on an engine. A very useful gauge in my opinion and much better than a gauge which only tells you if oil pressure falls below a certain level usually pretty
low.

Mine does not do that... It is about 3/4 on the guage when cold and gets a little higher with RPM and settles to about 1/2 when warm and with high RPM goes to 3/4, but never does it go "low to high" and act like it's moving with RPM guage.

When my engine is cold my oil pressure is at about 3/4 at idle. When I accelerate and my rpm's are near 2000, my oil pressure is right at High. After the engine warms up, 5-9 minutes, the oil pressure is slightly above 1/2 at idle and at higher rmps the oil pressure is between 1/2 and 3/4, but never reaches 3/4. I think this is perfectly normal...

I was at Frederick Nissan for an oil change the other day and talked with them about the oil pressure gauge reading high. One of the guys that works in the service department started up his Titan that had been sitting for a couple hours and it did the same thing, pegged the meter. I was concerned when I first noticed it but not anymore. Its just different than my Dodge Ram.

Guess I would not be worried unless it begged and stayed there...look at this thread.

New problem,high oil pressure

I was just about to ask this question myself. Glad to hear It's normal. You're right, I was used to my Ford Ranger's oil pressure guage that would hardly move...I see Ford got rid of it in the 05 Rangers...One of many reasons I decided to go to the Titan.

Normal, don't worry about it

I had an F150 before my Titan and the gauge never moved
