What the heck is "truck diesel:

hi
most of them have a larger hi flow nozzle for filling the truck tanks quickly and is sometimes unable to be used to fill the standard 4x4 tank due to pressure blow back cutting the flow
thats what i have experienced when i tried to use one and truckies dont like waiting for 4x4s to fill up
cheers

Thanks Mark, the Caltex website explained about vortex diesel but nothing about "truck diesel". No problem, just wondering.
Rob.

Spot on dereki,

Vortex has the cleaning agents in it so the reason it is slightly dearer.
Caltex have a variety of different diesels,

LOW SULFUR DIESEL
ULTRA LOW SULFUR DIESEL
DIESEL- ULTRA LOW SULFUR
LOW SULFUR DIESEL UNMARKED
AUTOMOTIVE DIESEL FUEL
DIESEL FUEL UNMARKED
EXTRA LOW SULFUR DIESEL
DIESEL-EXTRA LOW SULPHUR
NEW GENERATION BIODIESEL
VORTEX DIESEL-ULTRA LOW SULFUR DIESEL
VORTEX DIESEL-EXTRA LOW SULFUR DIESEL
Alpine Diesel (NSW, QLD)
Highland Diesel (NSW, QLD)

Therefore the price changes depending on the additives, sulfur content etc.
The problem is do we really know what diesel we are putting in our vehicles?

Cheers
Simon.

This could be one of the reasons.
Cetane Levels
•Different cetane levels of diesel fuel measure the ignition quality of the diesel fuel. Higher cetane level makes the diesel fuel burn more easily and evenly and therefore produces more power. The average cetane level of diesel fuel is 40 but large diesel trucks and pickup trucks prefer a cetane level ranging between 45 and 50.
Cheers Dave..

My guess is they are simply advertising that if you are a truck, you will get a discount for filling there.
A few years ago, b4 all the price rises that followed low sulphur diesel, and all the other excuses.... it was common to get 2 cents off the price if you bought 100 litres or more....i made that target easily with a long range tank.A truck wont fill if they know the diesel is sub standard.....and they soon find out with the kms they do....then pass on the info....it is pretty safe to fill up at an outlet if you see a semi doing so.

hi sk maint
hi after reading your thread on types of diesel i'm even more confused about what i'm buying lol
but thanks for the imfo
what i have been concerned about is the last 2 tanks i have bought from busselton w/ws the exhaust fumes smells like power kerosene rather than diesel fumes also used to get the same fumes smell when i use to buy from w/ws mandurah before the new highway opened
has anyone else experienced this
and am wondering if anyone else has experienced this
i am very familar with the smell of power kero fumes having run our tractors on it back in the 60s as some old international tractors ran on petrol start/diesel and power kero and diesel
i'm also aware that power kero is used as aviation fuel for some planes and it could be coming from residue of pwr/kero left in the tanker when changing over to diesel cartage
i know it wont hurt my engine and would have a cleaning effect on the injectors the mazda has the old stock standard fuel system so i'm lucky and thats why i hang onto it at 139000kms its just a pup
note:
despite it smelling like a jet plane it doesn't go any faster
cheers

Sounds almost as difficult as buying MILK... low fat, no fat, high calciumm skim, extra dollop......

hi sdg
my mazda filler neck has an anti theft/syphon baffle in it and i suspect that thats what causes the blowback shut-off when i try and use the hi-flow truck outlets
one day i'll get around to removing the baffle as the filler has a locking cap
as well as the keylocking flap over the locking cap
but then again in 13+yrs
no one has ever syphoned my tank so the saftey system has worked
cheers
