Hey guys I had just bought a 2001 jeep Cherokee sport pretty new to them still and recently when I'm driving and then stop my oil gauge goes down but then when I start driving its back up to where it normally is any ideas to what might be doing this?
(I think it might be the sensor not sure though)

Scored a factory tire carrier but nothing else was in the jeep. Just wondering if anybody could give me a parts list and pics for the carrier

the oil gauge tells you the oil pressure. oil is fed through the engine by a pump that spins as the engine does, at idle it is pumping slowly(low oil pressure), at high rpms it pumps faster(high oil pressure), the faster the engine is spinning the harder the pump is pumping, ensuring that oil is moving through the engine as needed to lubricate all the components.

I've got a quick question. I have a 93 5 speed and have been getting around 18-19 mpg average. things just started to cool off for winter here in oregon and i suddenly just got 12 mpg that drop seems too big to be cold weather and witner gas could it be a bad 02 sensor?

I've searched the forum and not really found what I'm looking for, maybe somebody can point me to a related thread.
my new to me 98 jeep xj sport, 4.0L, AW4, stock height, 225/75R15(fairly new), 163k Mi on original engine trans etc.
I found the truck makes a cycling droning noise between 60mph and 70mph(100 - 120km/hr), it's not overly loud but noticeable, there is a slight vibration throughout the truck that is more continuous than the cycling droning noise. I'd say tire balance for anything around this speed but the tire balance does not "cycle".
the cycle is very consistent, kind of a wraaoooow wraaoooow that is one second on, one second off, repeat. haven't pushed it too much past 120km/hr but it's cycle does increase relative to speed, I notice nothing under 100km/hr
any thoughts?
my vote goes mostly to the rear gear set, since it is the only thing that I can think of that has a cycling variable(small gear to big gear) but transfer case and slush box also qualify under that definition. my feeling thus far is that the issue is coming from the rear, but I've had other vehicles trick me with a sound/feeling that travels through the vehicle leading you astray

To calculate the true MPG,
1. I would fill up at a gas station, record mileage or reset odometer.
2. Run near empty, fill up. Record mileage again or record odometer.
3. Subtract mileage from #1 from #2, write down if needed, or just the odometer reading
4. Now, I would take that reading, and add 'plus 4 percent' or .04
Example: Total odometer reading for trip = 320 miles times .04 = 320 x .04 = 12.8 and then add 320 = 332.8 total corrected trip miles
5. Take 332.8 and divide by the number gallons on fill up: 19.2 Gallons
332.8 / 19.2 = 17.3 mpg
This looks right to me. I know it doesn't show low end and high end speeds where the speedo may be less or more off, but I think it gets close.
Any math wizards out there to confirm a bit?
Looks fine to me. Remember you're working with a percentage so that covers high and low speed operation. If you did "derp I drove for three hours and I think i did 52 so I'll subtract 6 miles" I'd be concerned lol. There is no need to wait for the tank to be at any level, just get the odometer reading and fuel dispensed.

So, the following is the correct example:
To calculate the true MPG
1. Fill up at a gas station, record mileage or reset odometer.
2. Run near empty, fill up. Record mileage again or record odometer.
3. Subtract mileage from #1 from #2, write down if needed, or just use the odometer readings.
4. Now at this point, take that reading, and subtract or add your '4 %' or .04 or whatever offset you are using (plus or minus)
Example:
Total odometer reading for trip = 320 miles times .04 = 320 x .04 = 12.8 and then subtract that from 320 = 307.2 total corrected trip miles
5. Take 307.2 and divide by the number gallons on fill up: 19.2 Gallons
307.2 / 19.2 = 16.0 mpg
And there you go. TRUE 'average' MPG.

It's hard to tell but when I'm driving 20mph or faster its barely on the first line

Well then thats completely normal. Look at where the hand is, its not too far from the 180 mark. Take into account the inaccurateness (yes i know, not a word) of the stock readout, that puts the temp at probably right at 180.
