Kinda like a 1/4 inch back and forth. Check the outut of the sending unit. A few minutes later it will pop back up to the max of 80.

Sometimes it will keep doing it, sometimes it wont. An oil pressure gauge can fluctuate for many reasons, including an actual automotive problem as well as reasons like fluctuation in oil temperatures.

Testing with a known good pressure gauge should. You'll need to determine if the oil pressure is actually changing, or if the sending unit or gauge is lying to you.

There is no relationship between oil pressure rising and falling and the pressure indicated on the gauge but voltage rising and falling will cause the needle to rise and fall a barely noticeable amount. 20 psi at 2,000 rpm, 25 psi at 2,500 rpm, and so on ).

Thus, a sporadically blinking oil light is probably the clearest sign that the sensor itself is on its way out. You will need to remove the oil pressure sending unit and screw this gauge in there.

Be certain the oil level is up to normal, then check the actual oil pressure with a test gauge. The needle quickly comes up to the “normal” range and stays there unless something goes horribly wrong.

When the oil pressure rises to about 10 psi the gauge needle moves to the normal position and remains there unless the gauge fails or oil pressure drops. Just recently i had my low oil pressure alarm go off at idle.

Oil is fed into the bulb under pressure, the same as in the vehicle engine, from a supply pipe that causes the bulb to attempt to straighten. Check the outut of the sending unit.

I Hope Yours Is Just The Gauge, But After My Experience I'd Either Go Buy A Mechanical Gauge Or Get The Truck Towed To The Shop.

An engine requires 10 psi of oil pressure per 1,000 rpm ( ex. If the gauge is moving back and forth erratically at idle , i would say the gauge is bad. This video shows my oil gauge bouncing up and down while driving through your typical city.

Still Doing The Same Thing.

It is still under warranty so i took it back to where i purchased it and they replaced the oil pressure switch; Testing with a known good pressure gauge should. If the pressure varies (drops) at engine idle, perhaps your pressure bypass is defective, or perhaps the oil pump is worn.

Note That Some Older Cars Might Not Have A Dedicated Oil Pressure Light, And This Problem Might Pop Up As A Check Engine Light In Those Cases.

Be certain the oil level is up to normal, then check the actual oil pressure with a test gauge. Have replaced oil pump, oil censor. It is moving back and forth very quickly, but not the entire range of the gauge.

Just Recently I Had My Low Oil Pressure Alarm Go Off At Idle.

The temperature gauge is similar in that regard. Locate the oil pressure sending unit on the engine (the parts store can sometimes tell you where it is), remove it and follow the instructions that come with your universal oil pressure gauge to hook it up. While driving the oil pressure gauge drops suddenly and the check gauges light illuminates.

Oil Pressure Gauge Flipping Out.

Kinda like a 1/4 inch back and forth. I was sure oil could not work that way. When it moves between these two points it does so quickly.
