Will one bottle be enough to treat my 1.8 diesel engine

One is enough, but make sure you add it to a full tank of diesel, does the job!

Does this help with rough idle in Astra 2011 Model?

It can do dependant on what the issue is, might be worth using something a little stronger like coma magic, or STP ultra

What's the difference between this and the standard STP diesel injector cleaner

This is apparently more concentrated for higher mileage cars

Do i have to put this is every time i fill up or just a one off?

It lasts for approximately 4000 miles
