I would like to point out that "premium" fuel is ALWAYS either #1 or #2, depending on climate.
It's like comparing "premium" gas to "unleaded". Premium is STILL unleaded, but not all unleaded is "premium".
It's not?
I'm pretty confident that the only separation between "premium" and "regular" is the additive package. This can be a meaningful difference though, as that additive package will increase cetane as well as lubricity.
These claims are remarkably similar to the claims made by reputable additive companies. When I'm at a station that sells premium diesel and regular diesel, I ALWAYS pick the regular stuff and treat it myself. I don't know exactly what additives they use, but I know what I use and am confident of it's effectiveness.
I seem to get better fuel economy on the regular diesel treated with Power Service than I do the "premium" stuff. I have also run the regular treated stuff in temps as low as -25 degrees with no gelling or performance issues.

Interestingly enough, I bought the "premium" diesel tonight. I was out of Power Service and wasn't willing to pay truckstop prices for it. So instead I bought GOLD DIESEL for 4 cents more per gallon tonight.
The 28 miles home, all highway, on a warmed up engine, I averaged 23 MPGs.
This seems consistent with what I normally get with regular treated diesel.
On a side note, there is a definite correlation between engine temperature and fuel economy. This aforementioned run was on a completely warmed up engine after running 17 miles on the freeway. When she's cold she gets thirsty. It takes a good 15 miles to warm it up, and during that time I get between 6-17, 6 being when the oil temp is around 25°, and 17 when it's around 150°. Running fully warmed up at 205° EOT I routinely see 20+.

Yeah, I'm a firm advocate of fuel additive!

I get the regular and add my own additive and its -20/-30/-40 for 6 months of the year here and have no problems.
