I have got a off road electric rc car and i just wanted to know how you can tell when to change the shock oil.

Depending on usage. I try to change oil on my buggy before every race, because even if you can't spot any difference on your pit table, old and dirty oil will behave a bit differently on the track where the shock action is a lot faster than you can simulate on a table. But if the car is just for bashing, then 1 oil change per season should be enough.

I go by feel; as soon as I can sense there is air in there (greater that how I built an emulsion shock to begin with), I rebuild. Typically ends up every second or third race night on an indoor track for me.

I rebuild it if I can feel air in the shock. Otherwise I will change it during the off-season.

I think it depends on the shock.

Better sealing shocks will let you go longer before changing oil.

Try to find out how long it takes for the oil to start looking relatively dirty, then you should have a good time frame that you know the oil will be good for.
