Just wondering what the difference is between Truck diesel & the diesel from the car bowsers. I pulled up at the servo yesterday and there was a line up at the diesel bowser, so I snuck around to the fast flow pump out the back, there was an 8 cent difference in price ( I didn't know this at the time ). Just curious why the diesel at the truck bowsers is cheaper, is there any difference in the product.

IF there was a Difference between the 2 pump's, they would need to indicate the difference.. similar to the difference between the different Petrol Price's..
- If there is no Indication that the fuel is Different.. it not..
- there are about 3-4 different types of diesel out there..
- Bio B20 Diesel [up to 20% bio]
- Bio B5 Diesel [Up to 5% Bio]
- Clean TecD [A cleaner Diesel they say]
- Vortex Premium Diesel
- Extra Low Sulphur Diesel (XLSD) Regular Diesel -- the Regular stuff..
If there are no indications that the diesel is different, I bet it all comes from the same tank's.. - The Truck do use a high flow pump's to help them fill those large tank's Quickly.
- The cars use a normal slow flow rate as most car's have a smaller tank, that would be filled with foam in no time..
That's Good to know that there is a difference in price. As I have just gotten a diesel car myself..

There are two types of diesel fuel, #1 and #2. #2 is what you get most of the time and #1 is closer to kerosene for colder climates. The major difference between truck and car fuel pumps, is the delivery rate, trucks can take huge fuel delivery rates compared to cars, so have larger nozzles and hoses.
I use a Truck Filling station which is not open to the public where they sell both Truck, fast flow, and "Vortex" fuel. Vortex is 2 cents a litre dearer than the truck diesel. I think only Caltex have a special fuel designed for european diesels. It is supposed to be cleaner and have less sulphur. My own tug is a 1990 GQ Patrol and runs on what goes in it. Bio diesel, no problems, truck diesel, no worries, Vortex, no way (I am a cheap skate when possible.)
I think you will find that the "premium diesel" is a "narrow cut" diesel,, ie it is distilled from a narrow temperature band at the refinery,,,, whereas "wide cut" diesel - the cheaper version that is referred to here a truck diesel is distilled from a wide temperature range ie 338-538 deg C, which, amongs other things, gives it better cold weather properties.
The "premium" diesel has additives for very cold climates and has a more defined calorific value for consistent performance anywhere.
The same applies to Jet fuel used in jet engines. The RAAF jets years ago burnt their fuel fairly cleanly but the USAF (American) jets trailed black smoke. The RAAF used narrow cut fuel,, ie Jet A equivalent and the USAF used Jet B which is wide cut. This allowed the USAF to source a wider range of fuel around the world and their engines were "tuned" for this.
We have a 2005 LC79 Landcruiser 4.2 turbo diesel ute and use both,,, and I can't tell the difference, so buy by price.

I filled up in Rochester, Victoria a week ago. They only had a fast flow tank.
I searched everywhere for the slow flow, gave up and used the fast flow.
When I went into pay, I said so to lady at counter. She said We only have a fast flow.
Never come across that before.
This is getting very confusing now.
I go to the pump, I fill up with diesel. I don't go looking for different sorts of diesel, just buy the one they are selling.
Where do all the others come into play, bio etc?
Just as a suggestion, in order to meet current emission laws, oil companies have removed most of the sulfur from the diesel. Sulfur is used as a lubricant for the fuel pump and injectors. Whilst the oil companies are quick to reasssure users that they have dealt with this by introducing an additive package to circumvent this, I introduce my own additive when filling up. This can be Flaslube, Chemtec or mineral based two stroke oil at the rate of 100:1 down to 300:1. The engine does run quieter and you get a small decrease in fuel consumtion.
This idea originated from old truckies that use to practice this, albeit using engine oil.
As with all things technical, I stand corrected.

The best and cheapest way to overcome the lack of lubricant in diesel, is to use a small amount of ATF or 2 stroke in your fuel to keep the injectors clean and pump lubricated. Lack of lubricity in fuel systems is more of a problem than most people realise. The bloke I used to drive road trains for always puts 2 stroke in the tanks since they introduced ultra low sulphur and drivers carry 5 lt of it if they have to fill up somewhere.
I will use either bowser. Normally my first choice will be the slow flow because I figure the fast flow is for the trucks & don't expect them to wait while I fill when I could be using the bowser for smaller vehicles.. Some places actually have a sign saying fast flow pumps reserved for trucks. I reckon my troopie almost passes as a truck though.
I have never seen a difference in price except where there is "upmarket" diesel.
Cunamulla has a seperate area for trucks with the fast flow pumps, the smaller vehicle diesel pump has ONLY the upmarket diesel.
I think this thread is very imformative and I hope it continues to be so....
what I know is I've put pretty well anything labelled diesel (and plenty of bio diesel) into my 1984 landcruiser over the years to no real disadvantage; in my opinion.
thing is....is there are much less likely to be choices at the diesel bowser once you get away from crowded places (why, I wonder?)....
(BTW, in NZ , diesel is still (much) cheaper than unleaded, as opposed to east-coast Aust...that is, just like it was here some years ago anyway...why, I wonder?)
