If engine oil intervals are long, then it sure makes a lot of difference BUT it doesnt make any noises. Transmission can start making noise and it went away in my case once.
Its recommended to get your cars auto transmission oil change @ 25 - 30k kms max.
And Manual ones's should be changed no later than 50k kms.
Gear oil becomes very thick, full of dirt and deposits, once i changed my mehran's oil many years ago, it came out like pieces of mud, first it was not coming out, then the mechanic put in a screw driver in the hole then pieces of grease started to fall out
