Intermittent oil light

your new Oil pressure switch might be not as trigger happy! if installed, the new one causes the flicker, we could see about the performance of your oil pump.

What is the oil psi ?

It is an older engine and the light is flickering at a stop after a oil change... They probably refilled with a thin oil like a 0W30 or 5W30. If you went with a thicker oil, it wouldn't flow through the bearings as fast and the pressure would be higher. Slip it into neutral to raise the RPM's until you get it changed. You could try some STP or Lucas oil treatments which generally increase the viscosity.

should be not zero to 15-20 psi at the test point.

the oil pump regulates the overflow to like 14 psi in the first place-

Its has two oil changes the first was too thin and replaced with a thicker oil. The two switch replacements and it continues. I will try the neutral to raise RPMs. What change am I looking for it to do?

high volume oil pumps are a bad deal. seals blow out creating a mess...not good~

you want lubrication to all points needing it...think of a little guy in your engine with a clicky oilcan...he just needs a few drops on the moving parts...that's all.

if you HAVE oil pressure, yippie, pretty much that's all we need here.

I have the same problem in my 2004 Mazda Tribute (aka Escape) I had only been using 5w20 full synthetic but since I went over 250K I thought a higher viscosity would be better and was told that by several people. My oil pressure has not been the same since. I tried 10w30 then went to 10w20 but it still has issues so I am considering going back to 5w20. However, 2 techs have mentioned that my dipstick tube was loose. I think that can be affecting the pressure as well. Is it expensive to replace the seal and dipstick tube?

wha---you wanna me to shop for ye~ rockauto.com would be my first landing spot...such a common vehicle are likely to find skads of them in your local savage yards for a song~

LOL No not shop for me. I don't have any mechanic skills but I can change my oil. I just wanted to see what if any opinions there were on my theory/s. I don't want to do something silly and waste money because I will have to pay to have any work done. I would be out of my element in a salvage yard but I have a friend that maybe could help.

My Escape was loosing oil could not work out why, then the oil light started to flicker , changed to thicker oil, finaly changed the oil switch the flickering stopped immediately

Just had the same issue. Ford mechanic said the oil sensor was leaking. Replaced it no more oil light. 261 bucks though. I know, I overpaid , but I didn’t want to do it. Apparently you have to remove serpentine belt and ac compressor. I can do that, but I was on the road. New sensors are like 30 bucks.

My codes keep reading injector #3 and missfire. I've replaced the same fuel injector, spark plugs, coils and fuel filter, PCM but started jerking and battery light came on abd oil light and oil smells like gas abd it won't start..please help me..

a friend of mine just bought a 2012 escape, and she had me drive it home for her. about a 46 mile drive. half way home, the oil pressure light came on at highway speed. I gave it some throttle and the light went out. ease into regular driving (steady at 75) and it came back on. stopped at a gas station and let it cool off for a minute and did a quick google search while I was in the skunkworks. now, here's a kicker. I have a much older mercury 2 door wagon with a 2.8 v6. I drove it rather abusively for about 12 years without much trouble. but when I finally put a mechanical oil pressure gauge in it to replace the oil warning light (that would light up at idle), I found out it had 0 oil pressure at idle. I kept driving it thinking it might scatter the bottom of the engine all over the road. but it never did. so, I'm thinking this could just be a common ford v6 engine issue. and as long as there's oil in it, it should be fine. but I'm wondering if we should use a premium oil like Amsoil or Royal Purple. I already use Wix or Wix made Napa Gold oil filters. decal on the windshield says next service is not due for another 5 thousand miles, or some time in October. but we plan on doing a full service on it tomorrow.

i have a 2005 ford escape xlt it has 205,000 miles on it. it needs o2 sensors and its reading a p0420. but this past week it started with the oil light coming on everytime i would stop and the RPM would drop under 1000. Please Help I am dont have the money to have it looked out and then worked.
