DIESEL RIP OFF

And, every pump that I have taken notice of, has a label showing the minimum amount to be delivered. From memory, most are 2 litres

There are a stack of these "pictures" doing the rounds on FB at the moment. A number of them have been photochopped, just to make the point...

I am interested in answer to DeanoH 's question. Caltex have vortex also more

expensive.

Is it just a con to make people think they're getting a 'premium' product such as with 'premium' higher octane unleaded for higher performance engines ?

The Premium Diesel is like the European standard (clean low particulate) and your diesel runs cleaner. Similar to the Caltex vortex premium.
Not many BP servo's have the premium diesel though so you have to look it up on the app to find it.

May I carry this thread in this direction ; what is the benefit, real or imagined, of

diesel additives that assail the eye at every servo and auto shop.

To allow for ullage.

3l of ullage space as required for ULP.

which one?

de waxers
de waterers
lube replacers
injector cleaners
line and pump cleaners
cetane stabilisers
demulsifers
and stabilisers

in order

stops it from waxing when its cold
absorbs the water into the fuel to let it burn (opposite to demulsifiers)
replaces the lubrication properties of sulfer not in ULSD (most people use 2 stroke or engine oil)
cleans the injectors by means of heat activated decarbonising chemicals
a detergent additive that loosens all the stuff in the lines and pumps so it can be moved around
helps stop the fuel from going off and losing its "dieselness" or from fractioning due to heat/pressure, also helps lift the cetane value, similar to octane enhancer does for ulp making it nearer to pulp.
makes it repel water so in theory it all gets caught in the filter/water trap
and stops the fuel from breaking down "age"

The pumps have a $2 minimum purchase. You will see it written on the side somewhere.

So what happens when you buy less than $2?

When I was learning English this was the meaning:

Quote:

---

minimum[ min-uh-muhm ]
noun [plural min·i·mums, min·i·ma]
1. the least quantity or amount possible, assignable, allowable, or the like.
2. the lowest speed permitted on a highway.
3. the lowest amount, value, or degree attained or recorded.

I think that is the answer....
