Will it work with car being stationery

Yes but i wouldn't burn a whole tank of fuel stationary. If you mean just while in traffic, yes as long as the engine is running.

when do you put it in?empty tank or anytime

It states to wait until tank is nearly empty then add immediately (ie at Petrol station and without starting the engine) before filling with approx 40-80 litres of diesel per full 430ml of additive. I used half in 40 litres

Is it recommended for EGR cleaning ?

Not sure if it cleans EGR But works incredibly great for turbo,DPF,and cat , best on market does what it says

How often can it be used as i do 600 mile a week and first one made a difference

It takes probably around 10 to 20 thousand miles for the carbon to build up in places like the EGR (exhaust gas recirculation valve ) if yours has never had this treatment you will have possibly noticed a difference before and after? Hope that’s a help
