High Flow Diesel

jules47 · The Happy Helper

That's interesting - I thought it was only that the hose was a larger diameter - quicker fill.

KFT · Guru

From what I can determine the only difference is the size of the nozzle. Some SUV's cannot handle the high flow rate or with some the size of the nozzle.

Delta18 · Guru

Jules and KFT are spot on, simply dispenser hose diameter giving a higher flow.

Some utes cant handle it either though my D-Max has no problem.

Well there you go - what is something I'd like to know (sorry for hijacking your pos,t Vaughan) - is what is the AdBlu that you see on the designated truck bowsers at Shell servo (I think) we sometimes go through the truck ones if they are not busy ad the rest of the servo is packed. But left this one because we didn't know what it was.

Vaughan · Veteran Member

Interesting first time I saw it was up North a month or so ago and on the pump said not suitable for passenger

Hi Flow is as says in other words it has a bigger nozzle and the diesel comes out quickly. Ad blue is a substance that goes in its own tank for pollution control. DO NOT PUT IT IN YOUR DIESEL TANK.

TheHeaths · Guru

Jules47,

Adblu is an additive containing water that is used to reduce emissions from diesels, specifically I believe from the exhaust. DO NOT fill, or put any, into your diesel tank as it will ruin your motor.

Vaughan, the diesel in Hi flow bowsers is the same as that in the low flow, or normal vehicle bowsers. The "not suitable" part applies to the bowser itself, as the flow rate is too high for small vehicles with restricted fuel inlets, and designed for use on trucks to allow reasonably quick filling of their very large tanks. Normal bowsers operate at about 40 litres per minute, Hi flow at about 80 litres per minute.

Jules never, never, never ever, put Ad Blue in your vehicle diesel tank, radiator, window washer, or washing machine, it will kill them

It is used by some truckies, (it goes into a special tank), and not their diesel tanks

It is injected into the exhaust system to help with pollution, when the engine is running

I read somewhere that someone accidentally put it in their windscreen washer bottle, and it destroyed the windscreen

Hope that this message is clear enough, do not use it

I doubt that as it is a fertiliser (Urea I think) base plus water. Definitely not good in an engine though ha ha.

Adblue is a brand name of Diesel exhaust fluid

Bruce and Bev · Guru

and its not recommended to use truck diesel in high compression motors (told the older low compression common rail is ok) as it does not have the various additives in it that helps to keep a high compression motor cleaner and reduce likely water in fuel problems (but not entirely with either). But all diesel mechanics I have spoken to say no to truck diesel

blaze · Guru

and truck engines are just as hi tech as your 2.5 or whatever in your vehicle only they are tiny compared to a truck, the principle is the same.

Hi smile

Not sure where you found those diesel mechanics, however that is rubbish. There is no difference in the diesel fuel and it all comes out of the same tank(s). Only difference is the high flow rate which can startle some "ordinary" drivers and cause diesel spills on the forecourt. All direct injection motors have lower compression anyway. hmm

The new truck motors have all the same requirements as your 4wd and probably more electronic controls too. The new trucks have DPF exhaust filters which need the Ad Blue to help the process. It goes in a seperate small tank near the main tank. DO NOT PUT IT IN ANYTHING ELSE as already said.

Cannot see why the need for all this discussion. The hiflow pump is just the pump. It all comes out of the same tank in the ground.
The nozzle is larger and so will not fit in some fillers and the rate of flow is higher so that the auto cutoff may be a pain in a smaller filler.

kezngaz · Senior Member

As mentioned before on another post not that long ago..
You DO NOT have dpf and adblue on the same vehicle, its either one or other.
Adblue is euro 6. Dpf is used with egr.
New European built diesels have started ariving here in oz with adblue. Egr/dpf is donkeys years old.
Cheers Kezngaz.

I understand that High Flow Pumps are tested differently to Standard pumps, I have been short changed by a High Flow pump and now when travelling I Q up with the locals and use the standard pump except when none is available ie. at truck stops.

i have a 70 series and it will accept the high flow rate without problems, mate has a 4.2 lt GU, high flow pipe goes in but he needs to feather the trigger all the time or it flows back and overflows.
Note some small diameter pump outlets pumps (BP) have a high flow switch to allow faster fill for large volumes, look for the black button above the volume display.
If you need a 140lt fill normal flow is like watching grass grow!

Got that one back to front. AdBlue is the old tech.

The new ECE standards require the turbo to periodically burn through the DPF. Works just like a catalytic converter on a petrol engine.

New trucks have this turbo burn off as well. A light and warning system displays on the driver information screen (dash).

Most warehouse/distribution centres require the truck to remain outside until the DPF burn has finished due to the extremely high exhaust temperatures.
Some new trucks have an electronic postponement system that allows the driver to temporarily halt a burn in progress for a preset period.

Feel free to read. I did and this is what i based my fact on.
Ad blue is in euro 6 european built cars. And has the legs to meet euro 7 when ever that is!!!
Our local VW dealer has the new V6 Amarok in that has an ad blue filler neck and tank on it.

Adblue (DEF) and DPF are different technologies to serve different purposes.

DEF is used to help cleanup NOX emissions. DPF is used to reduce particulate emissions from the tailpipe.

These are not mutually exclusive technologies, and comparing them is like saying your car can have headlights OR windscreen wipers but not both. Different things to do different jobs.

(kezngaz - not sure how you can say 'it has the legs to meet euro 7' - the proposed levels have not been set. How can they meet something that is unknown?)

because some one asked the question an most people like to air their thoughts on the subject

try the hiflow 1) if it fits in your filler
2) it doesn't splash back on you

Only problem you may have using a high flow is that it does go in a lot faster and tends to froth in smaller vehicles and takes a while to settle
Just means you may not fill your tank properly
For that reason I tend to use the standard pump
I have a prado which has no trouble taking the high flow apart from the frothing

Hylife · Guru

Imagine being a truckie and wanting to pump in 1,000 litres of diesel and having to use the slow car pumps.

OMG! you'd be there all day.

Hi-flow = fast bowser pump, sometimes with bigger hose and sometimes with bigger nozzle too and usually always with extra long hoses (because some trucks have tanks on each side of the cab).

We all know that diesel froths up really easy, so if you pump it in too fast when the tank is nearly full, you get bubble blocks in your tank filling neck, and that results in back-splash.
Eezy peezy solution. Just squeeze the hi-flow trigger half way as you near the final top up.

A low flow diesel pump/dispenser will dispense fuel at or below 40LPM. It will have a 20mm nozzle and 3/4" hose.

A high flowdiesel pump/dispenser will dispense fuel at or below 80LPM It will have a 25mm nozzle and 1" hose. Sometimes you will find a high flow bowser with a 20mm nozzle.

A Ultra high flow pump/dispenser will dispense fuel at or below 160Lpm. it will have a 32mm nozzle and is for trucks only.

There are also some 400LPM dispensers around in truck stops.

Ad Blu is a mixture of urea and water. It is highly corrosive. Used for emission control in later Euro trucks, Ford Everest etc.

Ad Blu is only to be put into a dedicated tank.

Thanks for the interesting numbers Techman54, but I guess that those are maximums, not minimums.
By minimums I mean, that on most modern bowsers you can always just squeeze the trigger half/part way to get a lesser flow rate without the risk of splashback.

Never try to fill a 20 ltr Jerry can with a hi flow pump, unless you are wearing a rain coat and protective eye wear :lol: The diesel rushes in so fast the air can't escape quick enough and the plastic jerry can starts to expand. When you let the trigger go cause you think you are nearly at the top, the pressure can now bleed off around the nozzle and the jerry can returns to its normal size...... what looked like nearly full was actually over full and that diesel is going to leave the jerry can under pressure..... you also have to clean up the driveway after the spill or risk being reported to the EPA as the servo owner is going to look for a scape goat if caught and your number plate and face is on the video.
