Who uses a fuel additive?

I have a buddy that has had several ford diesels and always uses fuel additives. Does anyone else use them and if so how often and what brand? New to the diesel world and trying to learn about them.

I've had diesels before and always used additives. With nothing but biodiesel available where I live, I currently use Opti-Lube XPD. It makes a difference IMO. Seems to run smoother and quieter, even during regens.

GM recommends ACDelco Fuel System Treatment Plus - Diesel. It's a bit pricey. After a little research, I think I'm going to try Stanadyne.
