Why does the oil pressure gauge change after an oil change?
Using these helps keep the oil at a constant viscosity. But as oil ages between changes, dirt and contaminants dilute the oil, so expect your pressure gauge to reflect that over time. You may notice a fairly large change in oil pressure readings just after an oil change. Oil viscosity or thickness is also tied to engine heat.
When to know if your oil pressure is high or low?
Before concluding that your car has a high oil pressure problem, it is a good idea to first check that the oil pressure gauge is working properly. If the car is on idle and the engine oil is hot – you normally have low pressure. If the engine oil is cold and you rev up your engine, the gauge should be much higher.
Is it normal for the oil gauge to read 0?
When the engine not running it is normal for it to read 0 since the oil pressure is created by the engine running. To have this corrected, I would recommend having a certified professional from YourMechanic diagnose the odd oil gauge behavior and assist with repair.
Why does my oil pressure go up when the car is on idle?
If the car is on idle and the engine oil is hot – you normally have low pressure. If the engine oil is cold and you rev up your engine, the gauge should be much higher. The best way to check if the gauge is correct is to use a manual pressure gauge.
Why does my oil gauge keep going bad?
If installing a thicker viscosity oil raises the oil pressure, then something major is wrong inside the engine. Besides, modern cars are designed to use very thin oil anyway. Gauge Problem vs Oil Pressure Problem Dashboard gauges do occasionally go bad, but it is very rare.

Is it possible to get an accurate oil pressure gauge?
Keep in mind, most gauges aren’t accurate. The only way to get an accurate reading is with a quality oil pressure tester. You will need to remove the oil pressure sending unit and screw this gauge in there.
How do you check your oil pressure while driving?
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. Then drive the car and see what the gauge does. Be careful to watch the road as you do this. Don’t become fixated on watching the gauge.
What causes the oil pressure to go up or down?
Then the gauge suddenly shoots upward to normal and the ticking noise stops. You have the wrong oil filter installed. Many engines require their oil filterto have an anti-drain back valve. That prevents oil from draining downward, away from critical engine components when the engine is not running. You May Also Enjoy:
What happens to the RPM gauge when you crank the car?
When I crank my car, for about 15-20 sec the rpm Gage goes from the 1 to 1 1/2like 13-15 times while making a clicking noise & then levels out. I’ve replaced the cam shaft sensor, spark plugs & throttle bottle position sensor.
What should the oil temperature be on a 2014 Jeep Grand Cherokee?
I have a 2014 Jeep Grand Cherokee Overland, and I am trying to gauge what ‘normal’ and ‘high’ transmission and oil temperatures might be, so I know how to interpret what is being displayed on the EVIC. Can anyone help?
How do you know if the oil pressure gauge is bad?
Some common indicators that the oil pressure gauge is not working correctly include: Oil pressure gauge not working: The causes for this range from a faulty gauge to the need for an oil change. Have a mechanic check the oil level. Oil pressure gauge reading too low, generally below 15 to 20 PSI while idling.
What should the Trans Oil temp be in a jeep?
On a highway trip, starting from a trans temp of 80F or so, it will take anywhere from 45-60 miles before it finally reaches 195F or so, depending on whether I have any spirited accelerations along the way. Note: neither the trans oil temp or engine oil temps seem to be super accurate throughout the full range.
Why is my oil pressure reading so low?
There are rare mechanical problems that can cause an unsteady oil pressure reading. They usually happen right after an engine has been overhauled. Advertisement If that sounds like you, then suspect a faulty oil pressure by-pass valve or spring inside the oil pump. Valves stick or can get installed wrong on some engines.
What to do if your Jeep Cherokee has low oil pressure?
6 people found this helpful. I have a 2003 Overland Grand Jeep Cherokee 4.7l V8 and also had low oil pressure problem. One of these websites suggested to replace the oil sending unit located above the oil filter. Did that and still had low oil pressure at idle.
What kind of oil pressure does a 1990 Jeep XJ have?
My 1990 XJ 4.0 has new rod bearings, seals and gaskets and runs great. Not a drip and I now have 5000 miles on the bearings at 25 hot idle and 42lbs driving. If it doesn’t smoke and the journals look good it can be done. Less than $100 and some elbow grease and you will be good to go. My Jeep XJ 4.0 has over 200,000 miles on it.

Why is my oil pressure reading so erratic?
Contrary to popular thinking, using an engine oil that is too thin will not make the gauge reading erratic on an engine that is in good mechanical condition. If installing a thicker viscosity oil raises the oil pressure, then something major is wrong inside the engine.
What to do if your oil pressure gauge is busted?
Try to step on the gas to rev up the engine. If the oil pressure gauge still doesn’t change its reading, your gauge is busted. It’s best to replace it as soon as possible because you won’t have any idea if your car is already low on oil overheating.
When does the oil pressure go up or down?
When your engine is idle or when you’ve just started your car, the oil pressure gauge will have a low reading. When the engine starts running and heating up or when you’re already cruising on the freeway, your gauge’s reading should increase.
Oil Pressure Gauge Reading Too Low. When your engine is idle or when you’ve just started your car, the oil pressure gauge will have a low reading. When the engine starts running and heating up or when you’re already cruising on the freeway, your gauge’s reading should increase.
