What kind of oil do you use?

vaccum pump oil - but be very careful as to not over fill - I haven't put 3 oz in the pump after the first fill. I use it to pull the air from Platnumsilicon mold material. Been using pump for roughly 8 months.

Is the internal "oil filter" effective or does it still put out a mist? Would you use it indoors in a poorly ventilated space?

Not for indoor use unless you use and exhaust hose venting outdoors. smooth noise but annoying after time indoors. Mist comes off mostly when you restart vac after releasing pressure to open vac it for whatever reason.I set mine outside an run the vac lines into the house eliminating all exhaust and most noise.I can only get -24.5 pressure vacuum.

How many inches vacuum will this pull? I need 29 to operate a vacuum bell jar

At sea level you will pull a high vacuum than you will at say 3000 feet. Probably wont pull much more than 26 at 3000'. Less at higher altitudes. This is normal. As you dont need as much vacuum at higher altitudes.

Do you have a decibel reading for the noise level?

Hello, I did not take a decibel reading. but I can say that it is just a little more than a 'hum'. Nothing that would be bothersome.
