As someone who has a 100 psi oil pressure gauge, I can tell you that it's somewhat less useful than the stock one. The normal oil pressure of a 350 barely registers at idle on my 100 psi gauge. It would be much nicer to have 60 psi be the highest number, so the needle would move. If the needle is pegged on the left at lower RPM, and is rarely seen to move, it's not a useful gauge. It would be better to just have a clock there because if the oil pressure did drop when you're just rolling around town and not getting the RPM's higher, you wouldn't ever know. Unless you wound the engine up to a higher RPM and that may be a very bad idea depending on what was wrong. You really need to be able to see that it's making the 8-15 psi it's supposed to at idle.

I get what your saying But 100 PSI works for every application and If you have a 60 psi it would be a little difficult to catch a failing motor cause your oil pressure would be at full pegged with a 60 psi. If that makes sense

Yeah it's a once size fits all gauge. But what engines will the people on this site be running? 305's and 350's mainly. A couple others like the 454. Maybe engines built for more performance than the stock ones will generate more oil pressure, and that's the idea.

I’m sure there’s a lot of LS and stroker motors also. But then again that’s 100 psi works for everything/build

I'd agree on the oil pressure gauge range & add the same argument for the tach & speedo - who's going to run any pickup to 140mph or spin the motor anywhere close to 8k. 100 mph & 5k RPM would be a lot more useful for most...

Change the sender and remember that the gauge will be a reference not a pressure reading. For example you switch out to a sender that makes your gauge show 20 psi at idle and 40 going down the road. Now if you start seeing 5 at idle and 15 on the road you know you need to investigate why. Figuring out the sender you need wouldn't be super difficult. Especially if you know the values on the sender you have.

They come with senders you don’t need to figure anything out.

You do if you are trying to make the gauge read different..We can add resistance that would make the gauge read lower but we can use a sender with lower resistance to make the gauge read where we want it to.

Every aftermarket gauges out there is setup the same. And send new senders. They read great with what they send that’s why they send them. Ya you don’t need 140mph but it’s also part of the modern look.

The one thing I don't like about my Dakotas. 160mph Speedo. I'd MUCH RATHER have more definition on a 0-100 or even a 0-120. Very few squarebodies doing over 100mph.

But the OP said he wants the gauge more usable for him,so I'm trying to help him.

Yup totally understand but the senders they send read pretty accurate. That’s all I was saying

But you see it doesn't work for every one, in the 1st 7 posts you have 2 people saying it doesn't fit their needs and 4 of the first 7 are yours so 2 out of 3 posts from members are saying these ranges don't work well for them.
