When it comes to filling up the 4WD with Diesel I don’t pay that much attention as I stop and fill up. The other day I was filling up with a ‘High Flow’ pump which isn’t anything new, but noticed a sticker on the pump advising this is Truck Diesel and shouldn’t be used Cars or 4WD’s.
So what is truck diesel?
I have a 100 series 1HZ Cruiser so it’s far from high tech. Also even when the car was new 15 years ago the quality of Australia Diesel wouldn’t have been that flash.
Also would have thought new trucks these days are just as high tech new cars/4WD’s.

about 20 cents a litre... ;D
I have a 1hz too and begrudge paying for "premium diesel" when I know that my truck would run on chip oil with a shot of whisky in it...
I can see how the quality of the stuff matters for the common rail diesels though.

Anti sudsing agent and a deodorant to make it less smelly for the women folk when they fill up the Audi, was how it was described to me by a fuel company rep.

That's about it....and all the blurb about premium having cleaning and performance additives ??

i always get further on a standard tank of premium diesel (caltex), as opposed to 'truck' diesel (caltex)...
your mileage may vary...

better fuel economy for me... documented over a long period of time...

And what is the additive that gives you this difference ??
I usually shove the diesel in from the local independent fuel shop at around $1.19....the other big players are around $1.25 to $1.35 ??

I have 2 Pajeros ('06 & '17), both seem to run better on the 'premium' diesel, particularly Caltex & BP.
Post by: lloydus67 on November 03, 2017, 06:48:16 PM
I get better mileage from both rather than Caltex
Around 50-100 klms out of a tank difference, however Caltex is usually cheaper

High flow diesel is only for vehicles with fuel injection, not if you have a carby!!!!!!
Nice to look at but.

No idea. Not a fuel expert.
Just know that premium diesel works better in my ute than truck diesel.
As I said, others may experience a different result.

Considering at least 40% of diesel is imported into Australia and the rest comes out of four (4) Aussie refineries, what you are getting from a BP bowser is probably Caltex or vice versa depending on location or is from Asia and every servo in town is selling the same stuff albeit with some different additives. And none of the additives can improve economy or performance except maybe giving your fuel system a bit of a clean if it is an older engine but any gains diminish after a couple of tankfulls. Saying one brand gives better economy is just not scientifically provable, sorry.

that's cool... don't doubt anything that has been said in this thread...
as long as you can just explain to me why i consistently and measurably get better economy using one form/brand of diesel over another.
others (on this forum and others) have also said that they get better economy using a particular brand of diesel over another.

Prove it to me scientifically and I will believe it. Otherwise I am happy that you are happy in your beliefs.

Have all your economy tests been along the same roadways?
Have you changed vehicles during the period you conducted the economy tests.
So not just measurably different in only your current vehicle?

As accurate as anybody else's...
Same road, same vehicle, same route, different servos selling the same fuel, over months...
I only have one diesel vehicle, so haven't tried another vehicle.
I am smart enough to do the figures and to come to the conclusion that I get better economy with one brand of diesel over another.
If this doesn't fit with the narrative, that's cool... 8).
Until someone can definitively prove that one brand of diesel can't provide better economy than another, then I am happy to live in my fantasy... ;D

Just wondering if you were having a consistent benefit in more than one vehicle.
I have found some vehicles are better than others in the use of their fuel, even from same model of same manufacturer.

I'm not having a go either.

No worries here, mate... :D.
If someone wants to provide me with another diesel vehicle for nicks, then I'll happily test it too... ;D
I totally get the what was said about where our fuel comes from, etc...
I just have my figures to go on.
I don't know why or how and also understand that others might not see this benefit, but I do and that's good enough for me...

There is a difference between regular diesel and premium/ultimate/or whatever else they want call it diesel.

Really there is no difference between truck diesel and regular diesel except the large size nozzle at the bowser that allows for 'hi-flow' and the large nozzle will not fit in to the regular diesel car filler.Hi flow fits all our cars, rangie, amarok, and iload.

That article looks american. Do you have any actual data from Australia that isn't advertising to back this?
Just curious to find out.

Sorry, just did a very simple google search, something you could do yourself, but basically the result will be the same.

This is good for older diesels as it flushes the diesel system out. New diesels it is a waste of time.
Something i did find interesting is the standard diesel with its apparent 'foaming' issue, give a false reading on the guage due to foaming in the tank. This may be why when you put a premium anti foaming diesel in, you get more k's to a tank.

No, diesel foams naturally. They add an ANTI-foaming agent which takes all the refuelling pain away ;D

I did a bit of googling and found that the Puma fuel can have up to 20% bio diesel but I'm not sure what we purchased as my Wife binned the receipt.
I also came across this post when researching PUMA fuel so think I will stick with BP or Caltex from now on.
Lindsay transport just did a 6 month test using BP ultimate diesel in two of their Kenworths. They had a full history of the trucks and after the 6 month test they went back to truck diesel for another 6 months. There finding was that the trucks returned 3% better fuel consumption with the ultimate diesel and when the heads were stripped the combustion chambers and valves were in good nick with little carbon. One thing is, the ultimate diesel is dearer than standard diesel. https://www.exploroz.com/forum/130755/puma-fuel (https://www.exploroz.com/forum/130755/puma-fuel)
