Oil light on at idle only. Engin light on continually, got an oil change at Walmart before this started happening before my trip.


this is a clear indication that the oil pressure is not enough at idle , since you noticed it after an oil change , im guessing that its maybe possible the improper viscosity oil was used in your car , anyway its not good for the engine to have the improper oil type or pressure regardless of idle or full speed , as this causes premature engine failure , also note as I worked in a dealership for many years cars that came in with an oil related failure there oil/fluids were always Lab tested for a warranty repair and once or twice out of 20 or so I actually saw a warranty claim denied biased on a labs test result (meaning that the owner was responsible for the repair )

there are other reasons that the oil pressure can be lower as a engines life gets older as well , but still it is suspicious that it just showed up after the oil change , normal engine wear shows up gradually over time , not all the sudden

Oil pressure


Hi. Your symptoms are a strong indication of major sludge build up in the block region. This type of thick build up will clog up the oil ports, thus, reducing the normal flow of lubricant throughout the engine. This will cause fluctuating oil pressure, as well. Although this issue is a common cause of your symptoms, there are others. The next cause of fluctuating oil pressure will be a failing oil pump. This device can fail mechanically(gear failure). When this occurs, the engine oil will not circulate properly, thus causing the symptoms you are experiencing.

In conclusion, This type of problem will require you to administer a manual oil pressure test. This will confirm the oil pump failure. If the pressure test reveals that, indeed, the engines pressure readings are low, the oil pump will be the culprit. I recommend to administer a engine flush, and change the oil pump and oil pump screen, as well. Now, if the manual pressure test reveals that the pressure is optimal, this will indicate that the presser switch(sending unit) is faulty.

My red oil pressure light is on for the first time


barbered: if checking the oil level did not resolve the problem, the next step I would take is an actual mechanical oil pressure test. Electronic oil pressure sending units can fail, consequently give false readings and/or false alarms. "YOU USE THE TERM "BEING A WOMAN".
Is there a reason you must make an apology for you gender? In my shop, my top tech happens to be a "WOMAN"!
I am close to 60 and ranked in the top 10% on ASE testing at the time I had taken it as well as gone for recertifications. Additionally I did exceptionally well in my Nissan factory school training. My mentioning this was to state that Between my years of experience training and test scores, I should be qualified to judge a qualified technician when I see one. At her mid 40's I would pit her against many technicians with 10 years more experience and bet she would make them look like fools!
Getting back to your problem: The sending unit is designed to complete a ground circuit to the bulb you see lighting up, when the oil pressure drops below (I believe) 6 or 7 psi. This is when there is no longer enough oil pressure to circulate throughout the engine, consequently, the continued operation will cause the engine to self destruct. (You were wise in deciding to stop running the engine until you got some answers! ) The best way to determine if you have a safe situation for the engine, is to test or have tested a manual oil pressure test.
The oil pressure sending unit is screwed into the side of the engine block on the same side as the oil filter and uses an NPT thread which is the standard used by all universal oil pressure gauge kits.
You can buy a cheap oil pressure gauge kit to make a test tool. Using, I believe either a 12mm or 14mm (there were two different size units used) open end wrenches, Carefully, remove the sending unit by rotating the sending unit in a "counter clockwise" direction.
Keep in mind that these are "TAPERED" threads, so when you install the test tool, do not over tighten it as well as when you either reinstall the sending unit or replace it with a new one, tighten it carefully, until it feels pretty snug, but you can't reach up and spin it off with your hand. When you put the part back on, use teflon tape on the threads. Home Depot is one source and it's cheap as well as they can tell you how to use it. When you install the test gauge, make sure you have another person with you so you can watch for leaks after the engine is started. At an idle, the pressure will normally be between 15-20 psi. When you rev the engine, it will jump as high as 60 psi. If you get these readings. All is fine. These readings are usually checked when the engine is at operating temperature. When the engine is cold, it may read even higher for a brief time.
Maybe what I have offered will shed some light on the subject for you. I try to be more descriptive on things because I feel that if people who don't know how things work, learn how they work, then it is easier to grasp the concepts of what an answer is about rather than GREEK to some who view it and a solution to others.
Good luck and I hope I have given you the solution.>>>>>>>>>
