What's the point of the vacuum gauge ?

fun to watch and you can actually watch the vacuum gauge to maximize mpgs.
why do they make one if there is no point of one?

I've typically only seen them on forced induction vehicles.

what's the point of having an oil pressure gauge? vacuum gauge is just as useful for knowing when things are not optimal, and more useful for routine operation

Buying a ford fiesta will maximize your mileage too.
I certainly don't jump in the jeep to get great gas mileage.
On the other hand, if you were going to put 2 more gauges in a jeep, what else would you pick?
All the ones I could think of belong in a performance vehicle, not bolted onto a tractor engine.

not going to put a EGT guage...lol
fuel pressure would be cool, but they are expensive...

Trans and oil temp would have been my choices.

A vacuum gage is the most useful gage you can add. If you drive by not letting yourself go below a predetermined vacuum level, you will maximize your gas mileage. The gage will react like there is a string from your gas pedal to the gage.
Yeah, I know, buy a honda if you want good gas mileage. Sorry, when I drive a vehicle, whether it is a little 4 banger or a big V8, I do give a shit about not wasting ga$. You can still floor it for a thrill, but no point in wasting gas when you aren't even trying to go fast.

I think there's a difference between maximizing your mileage and realizing the limitations of the vehicle you're driving.
Let's say for arguement's sake that you get 16 mpg daily driving. We're not talking taking a long trip with the cruise on, just your average get you to work and back and around town and back home. If you're like me and you live 20 miles from work (mostly highway) it's pretty balanced between acceleration and cruising.
So you get 16, times about 17 gallons (because nobody runs the tank dry) is 272 miles. Right now, gas at my house is 2.49 a gallon. So to fill that tank back up, you're going to spend 42.48. That's 6.4 miles per dollar, if you're keeping track of that sort of thing.
Let's say you really baby it (and spend the money on a vacuum gauge, which is another conversation) and get 18 mpg. Again, let's be realistic about where we're driving. That's 306 miles. So on that 42.48 you're going to spend to fill up, you're getting 7.2 miles per dollar.
Now if you're me and you drive 40 miles round trip, 5 days a week, 50 weeks a year (for arguement's sake) you're driving 10,000 miles a year. At 18 mpg, you're going to spend 1388.89 on gas. At 16 mpg, you're going to spend 1562.50.
So for the constant attention and focus that what you're suggesting requires, you saved $173.01 for the YEAR. I spend more than that on lunch in a month.
I guess if it's worth it to you, pay attention to it. I can't justify the work it would take to save what amounts to 14.47 a month. I'd rather just drive and enjoy myself.

very interesting.
I got these for free from a friends car.
I did go out and buy a hole saw set though

And when gas goes up to $5/gallon, you save $346/year. That's almost 2 cases of cheap beer a month. I know, you buy the expensive beer too. Your comparison is very accurate and well thought out. Us old farts are just too cheap. And we walked 5 miles to school uphill both ways.:cheers:

I dont think I would even waste my time installing anything else, and I'm not really that sure if I would install the oil temp.

Interesting, Been thinking about doing a Trans temp, and a Pressure gauge for my OBA tank infront of the shifter..
I enjoy having a clock.. You should of just replaced the bulb!

what bulb?
I have a 96, there wasn't even a plug back there

i have an air/fuel gauge in front of my shifter. took out the change thing, cut metal, installed 2 switches and a gauge. and called it done.

How do you determine the best vacuum level for mileage?
I've been wanting to add an extra gauge or two.. I know I want a transmission temp gauge, but the other one (or two, depending which gauge pod I find) are up in the air. Maybe a secondary oil pressure gauge

i have a 2 gage A-pillar pod with a trans temp gage and a volt gage (my stock one is terribly inaccurate). my OBA gage and switch is mounted to a bracket on the knee panel by the center console.

I wouldn't mind having a vacuum gauge in my dash. Infact, I had already been considering one in the rock rig. I never took fuel mileage into consideration. More or less for an aid in driveability diagnosis. Depending on what that little needle is doing will tell you a lot about what is going on in your motor. If you know what you're looking at you can adjust timing, adjust fuel trim, even know if know when you're floating valves if you rap out the motor that hard. Vacuum can be used to know so many other things. Good mod.
