Thread: Vortex diesel V ordinary diesel

well it certainly doesn't foam up like the other stuff , so you don't stand at the bowser for an extra ten minutes just trying to fill the tank

This is a quote from, Drive.com

Unlike premium unleaded petrol, premium diesel has no performance advantages. However, it's claimed to do a better job of cleaning your car's engine, which over time could lead to better performance and economy.
Premium diesels such as Caltex Vortex Diesel have less of an odour and contain an anti-foaming agent to help prevent the frothing in the tank that can make filling a diesel more time-consuming.

I always thought that Vortx diesel and ordinary diesel is the same thing as you can only buy Vortex at the Caltex garages I go to - assumed it was just a marketing thing to make Caltex diesel sound better.

If there is a difference why can you not buy "normal" diesel at Caltex garages and Vortex is the only option.

I did like that it doesn't foam up as much that's better. But I know there's only 2 servos in my town a caltex and bp and the bp is about 7c a litre cheaper so I go there stuff the vortex haha

Caltex sell normal diesel and vortex in some markets (vic). I think the premium diesel has a higher cetane rating. I was using BP exclusively, and noticed a10% improvement in economy when I used vortex.

I've seen some Caltex Servos that offer "Truck Diesel" as well as Vortex.

Usually the "Truck Diesel" (as they call it) is a couple of cents per litre cheaper.

Whether you get any extra value from the extra two cents I can't say.

I think the truck diesel thing is just to get trucks to fill up there

Sometimes one truck fill is equivalent to about 10 cars , basically selling in bulk.

Vortex is an additive, usually added automatically while the truck is being loaded.
Some Caltex terminals do not have motor spirit, so source it from 'opposition' terminals. In these cases 91 RON ULP is sourced and (if the driver remembers) 4-5 litres of additive is tipped into the compartment to convert it to 95 RON ULP.

Some years ago Shell added an anti-foaming agent to their diesel, it clogged filters and was quickly dropped.
