Question about 2003 Nissan Altima
Blue smoke indicates burning oil. So you oil getting into your cylinders somehow. Could be broken oil ring on one piston. If you have a lot of miles on your car or it has been overheated your engine may need an overhaul.

It sounds like you could need some new piston rings. when they go bad it causes oil to get by into the combustion chamber and burn when the engine fires.

Sounds like its flooding(excess fuel)Try squeezing the main fuel line enough to allow enough fuel through for engine to run smoothly if that improves running of engine either fuel pump needs replacement or pressure relief valve has failed or has no vacuum to activate it.Dirty or failing injectors can also cause your problem,try putting a can/bottle of injector cleaner in fuel tank to see if it improves running of engine.Air flow meter can also be an issue.A few potential reasons foryour problem and too hard to lock it down to a single cause without the vehicle being in front of me to do the appropriate tests so have just provided the basic causes and hope your able to take it from here and solve the problem.Good luck

SOURCE: Blue smoke comes from tailpipe
A lower octane gas woudn't cause it to blow blue smoke, more like it needs an engine job. There is oil getting into the combustion chamber, could be valve guides, valve seats, piston rings worn.
