It generally seems to cost about 2c/litre more from stations that sell ordinary as well as premium, which is only about 1%, so if there's any benefit at all, it's probably worth it.

I haven't owned a diesel for about 25 years, so was wondering if anyone had found any benefit from using premium.

I reckon its a scam for car drivers using diesel. Most servos selling it have the "Premium" diesel pumps taking up most of the court usually leaving 1 regular (usually Hi Flow) diesel pump in a less obvious spot to find. Can't not see it being cheaper though.
