Fuel Additives vs Premium Diesel

[superhans88]

I appreciate both of these subjects have been discussed in great depth before, however is there any consensus on which is more effective?

I generally use premium diesel, more as an insurance policy against clogged injectors etc rather than for any performance benefit. The price differential of £5-£10 per tank got me wondering if it would be better spent on additive products instead? I have no experience of using these and have generally regarded them all as being akin to snake oil.. can anyone prove me wrong?

I give it an oil change every 6 months which works out about 10k miles, fuel filter is also changed every 20/30k or so.

It's the 1.6 TDCI (PSA) engine which has a reputation for turbo & injector failure, although mine is running nicely at 140k
