I guess you already know on at least the 89-up (could even be the 87-up) most Ford oil pressure gauges are fake. All you have to do is look at your oil pressure sending unit. If it's a large round can, it's the real thing. If it's the smaller switch style, then it's a fake gauge. They put a resistor in the cluster circuit board with the correct resistance to make the gauge always read right in the middle for oil pressure. The only way the oil pressure gauge would drop is if the switch made contact because the oil pressure was less than 5 pounds oil pressure. Another great Ford idea. That shows you the value Ford gave their own cluster gauges for giving information.
Oh I thought we were talking temperature my bad, I hate the fake oil gauge tho, a 7psi fraud of shame. Probably wouldnt even work that well when it gets that low.. my opinion at least lol. There should be a dummy light if they wanted to be *****s about it

They did that because “The customer is always right.” People complained that the needle in the oil pressure gauge moved around too much so they installed a resistor on the circuit board so it didn’t move around so much. The needle goes to a set point based on the resistance and stops.

They did. That’s what the red engine light or check gauges light is for.

You are exactly right. So much for the gauge giving any useful information.

Im saying that instead of the oil pressure gauge, there should be a dummy light,. I was implying that there shouldnt be a gauge for oil pressure since its not a gauge and there is a dummy light, i should have been more specific. I would like to have seen a ATF temp if they werent gonna use it lol . But of course that is forever ago now so cant change their choice to do that

Customer complaints turned it into a dummy gauge. You can change it back into a functional gauge. That’s what I did on the ‘89.
Well... I'm feeling pretty solid about my decision to run redundant gauges.
Too bad there's no good place to mount em.
My fuel gauge is very accurate: full is full and empty you better be looking to stop for gas. The voltage gauge is a real gauge. I converted the oil pressure gauge back to a real gauge and after having the truck for several years, I know where the coolant temp is when everything is good so I know when there is a problem. I see no reason to install aftermarket gauges but to each his own. Not only that but I don’t like the look of added on gauges.

As long as your gauges read in the "normal" range, you should be good to go correct? Or do you start getting worried when your oil pressure gauge reads on the "O" or maybe the "N"?
When should you start worrying about your engine temp? As long as it's in the "normal" range? Or do you start getting worried when it's on the "L" or maybe the "A".
I guess that is why Ford made the dummy resistor and gauge. Too many people were complaining their oil pressure gauge was on the "N". Silly people, it's still in the "normal" range!

You’re dead set on making a mountain out of a mile hill about the OEM gauges. In your case, throw the factory cluster in the trash and build your own from aftermarket gauges.
Do you get worried when your oil pressure gauge reads 29# instead of 33#? How about when your temperature gauge reads 197° instead of 206°? Is it time to figure out what is going on?
You know as well as I do that you can tell from after years of driving your truck if something isn’t right. You don’t need a full sweep gauge with numbers to back that up. The factory gauge does that job just fine for me.

I would be nice to have a range so it was clear what the realistic temp , pressure, etc range are, but its not the end of the world or anything. But hes definitely over worried. But since these gauges are not linear, the numbers couldnt be at just the front and end lol, youd need a middle to be able to know its not linear.
I am not worried, I have aftermarket gauges in my vehicles. I just like making fun of people relying on the stock gauges to troubleshoot and monitor critical functions of their engines they care so much about. Go back and look at this thread and the debate on what is good on these gauges and all the different places everyone's factory gauge reads at. And this is not the only thread on this, there are about a dozen. Most of them start out "I changed my thermostat, my clutch fan, and my radiator, and my temperature gauge still reads to the right side".
