Thread: Diesel queries

This would seem to be an appropriate place to ask what the difference is between ordinary "diesel" and "truck diesel" as it is labelled at some service stations?

One obvious difference is that the "truck diesel" is delivered via a hi-flow nozzle at a rate that is way beyond the capacity of my Defender's filler neck to cope with.

Is it chemically different?

I use Caltex when I can, but that's more due to a) the level of customer service and b) the quality of the facility (i.e storage tanks).
I've found I get less out of a tank of Shell diesel, however that might be because they don't have the option of the "premium" diesel, such as the Caltex Vortex.
Not a fan of the other servos in town, I know a local BP has had issues with water in their storage tanks.
I go where I trust.

Zero difference here. I keep track of fuel economy and my egt gauge has never picked up a burn temperature difference either.

I don't believe it is chemically different, but I'm no expert,,, (well maybe,, x = unknown quantity, and spert being a drip under pressure,,, )
Its just high flow. Where I usually get my fuel, they have a truck hose on the "Extra" bowser too , makes for a quick fill,,, except when filling up the jerry cans,,

My experience echoes most posts.

However, It depends on where the diesel is sourced. Most oz diesel comes out the one refinery and thinks that may now also be on way out.

As to where it is sourced, I have found that servos served with diesel out of Darwin get crappy diesel. It comes in from Singapore or somewhere else handy and I suspect that it has less KJ/kg than the fuel sourced from "South". Have always found on my trips that the ltr/100 went up by one or so, and then improved immediately I filled up with diesel from an Oz refinery when going back South.

So that was north of Alice, West of Cairns and T'ville and can't recall but think Broome as well given that the D2 was getting between 7-800 a tank on hwy. Going in next fill after would show increased consumption. Simply the "not so good" fuel is everywhere that the Darwin tankers show up. Are/were they Toll?

Was going to fill up today at the Coles/Shell with my 8c a litre off docket (god I'm cheap) but the tanker was in dropping off a load, so I kept going. Just in case there someone who doesn't know, never fill up after a tanker has dropped fuel, it stirs up the crap from the bottom of servo tank.

The responses from people in other states are not really relevant as fuel varies completely state to state (in terms of where it comes from).

There is no such thing as BP diesel in SA. Most or all of the diesel sold in SA would be from the ExxonMobil refinery. They have "product sharing" arrangements with the retailers in each state.

E.g. all diesel sold in WA from Esperance to Geraldton comes from the BP Kwinana refinery.

In QLD All diesel comes either from the Caltex or BP refineries.

Some refineries will get tankers in from OS when the price is right, and big users like mining companies will ship in their own private supply from the lowest bidder, however for the average purchaser, this fuel is rare.

What colour is your Singapore diesel? Every now and then I hit a batch of green coloured diesel and people who used to work at petrol stations (friends in high places) tell me that was sourced from Singapore rather than refined in NZ.
