Your user name is cute. Please use punctuation. It takes you longer to type periods, but it takes us less time to read and understand your posts. It's a simple courtesy.

Sounds like you do need to add grease to the threads, since you are hearing a creak.

what sort of BB...a sealed one?

i'd re-do it, might have a hell of a job removing it next time.

It is pretty important. Seized bottom bracket shell threads can mean a bike with worn out BB bearings but that is otherwise good is basically trash (although most BBs can eventually be removed, it can be a major headache). The correct answer is: 'Disassemble the BB, grease, and re-assemble.'

BTW, what sort of bike is it? What material is the frame?

I don't think that will do it. I'd go down to the hardware store and get some real grease. You can use the kind intended for cars.

yeah, that wouldn't cut it for the BB

might be ok to use on old chains, i use something similar on old bikes - Boston, then after some use, decrease the drive drain and hit it with proper oil

That stuff is oil; grease is thicker and not liquid. Most greases for automotive or marine applications are fine general purpose bicycle greases.

There are many around here who use, way, too, many, punctuation, marks.... I am sure they would be glad to loan you a few.

Re: your BB: personally I would disassemble and redo with anti-seize or grease; however don't assume that the creak you hear is coming from the BB. There are many other probable sources

Anti-seize lube is the right stuff for threads.

I agree with everyone else, disassemble and grease those threads!

Thanks for the tip on the 3-in-one Bike Maintenance Spray. Says it can be used on the wood and glass parts of my bike--I've been looking all over for something like this .. . . .

If you think you did a good job assembling the drivetrain, I wouldn't mess with it. If it's creaking, how slight is too slight? The only value on the grease is to reduce strain on parts during assembly and, to a lesser extent, to protect the threads from corrosion. If you'll be doing maintenance in the next 12 months, it probably won't make a difference to the parts.

You have run up against what I identify as the bureaucrat, who reminds you of forms you didn't fill out or, succinctly what Kafka talked about.

I recently discovered this personality anthropomorphy to working on a fixed gear; There used to be, maybe it's called a meme, an image of warriors who were holed up on islands or other remote areas who didn't know the war is over and thus fight to the last breath of all, which I compared some bike fixes or tunings to but other analogs apply. Of course the former was always in plain sight when the idea of having enough spare parts or a standard was hoped for.

If you're OCD about maintenance, and rebuild the BB every two or three months, enjoy the ride. If you're like most of us and ride until the BB is worn out, take the cups out NOW and add grease (or Teflon tape). Missing two or three months of prime riding season because the bracket is still soaking in penetrating oil is no fun.

Personally, I would remove the bottom bracket, grease it, and reinstall it. It sounds like a pain but it will take only a few minutes.

Easy answer.

Anything (grease on threads, orientation of tire labels, cable routing) that bothers you enough to ask about you have to redo. Actually it's a great time saver because otherwise that's all you'll be able to think about every time that you ride.
