Check oil pressure with gauge if low it's the pump, if ok then it's a faulty pressure sensor

How much oil is it using ?
Some newer engines go thru a quart pretty quick.

Is it too cold at 0 degrees to figure out the real problem?

There may be water in the gas tank. If there is, then a complete fuel system flush is in order and replace the fuel filter. Make sure the engine is warmed up some before you try to start it. Oil doesn't move well inside the engine at that temperature. A block heater and a battery heater , if you don't already have them , should be used.

What does the message "engine power reduced" mean on a 2011 GMC Terrain?

It means the PCM has seen a problem with your engine running and has reduced the power for your safety. You need to bring your vehicle in to someone with a scan tool to read your trouble codes so they can look in the right direction to repair the non-performing part.

My cylinder is misfiring on my 2000 gmc jimmy

replace fuel filter, air filter, spark plugs, wires, distributor cap /rotor, if you have one. new oil with your filter ? just thought I'd ask, have a auto parts store pull code to see why your service engine soon light is on. this will tell you what sensor needs replaced, I'll bet its the oxygen sensor !

I have an 2004 Mercury Mountaineer it has 207900 miles on it , this morning I was cruising on interstate at 75 mph I started up a hill and it would only go to 70mph I turned off the cruise and tried to...

It is possible that when you had an oilchange the oil used was 10/40 which is correct for this vehicle BUT i would advocate that a thicker oil is used for this mileage say 20/50.
all cars will use/burn oil and i always ask my customers how much oil they put in from the last service so that i can judge what oil to use.Thin oils (5/30)should only be used for new cars,and even then
keep an eye on oil usage/burn.....
We have all read,in various publications that "using the wrong oil can cause damage"but after 40 years in the trade,i have NEVER had a complaint or any engine damaged by this method of filling
