Apart from premium fuel, how do I stop my direct injection petrol engine becoming clogged?

I've recently bought a Toyota Auris with the 1.2 turbo petrol engine (and am very pleased with it so far). I intend to keep it for a good long time; at least 10 years, ideally. I understand that direct injection petrol engines like this one can suffer from carbon deposits clogging the injectors and would like your advice on how best to avoid this. I only use 'super' fuels - normally Shell V-Power, currently BP Ultimate as our local Shell is being re-built. Is there anything else worth doing?

You're doing the right thing. In indirect injection engines the fuel/air mixture coming in via the inlet valves cleans them. With direct injection it doesn't, so it is more important to get the cleaner burn that you will get with Super.
