to me, diesel was diesel, and im sure most of the population assume the same.

Well, most of the population don't know or care about differences in things technical unless/until it actually affects their life in some way. Like concrete - there are many, many types and none of them set by drying. But not many people work with it themselves.
But I'm surprised an apparently technical person like you didn't at least know that there is winter diesel and summer diesel.

Be fair,
 
I didn't know that either, an I am a "technical" person,
concrete hydrates, thats why Ice is used when concrete batching such as on dams but "technical" at what?????????????????
 
Supermarket fuel accounts for the majority of fuel sold here in OZ, to the extent that the duopoly, namely Woolworths and Coles are under investigation for all sorts of things, pricing etc but hey the Government is weak and they, Woolworths and Coles, are too big so nothing will happen.
 
The other 'good' thing is we are now shutting down all our refineries and are importing all fuel rather than process our own its cheaper to import Petrol from????????????????.
 
Fuel Quality, brands, etc now means nothing.

 %).......& RAAArty says....... "its cheaper to import Petrol from?" ............PETRONAS in Malaysia...or Singapore..........

It was reported that the largest single refinery in Singapore can daily produce approx. 10 fold of the total Australian production of cracked fuel output

We sell our coal, iron ore & LPG away at rock bottom give away prices  >>:-( ...yet our OZ fuel is still based upon the Singapore per litre price in US$

This was courtesy of a previous OZ Prime Minister ....Mr Paul Keating. :o ...[also a part owner of a Malaysian pig farm  O0] ....

Sorry my friend, no offence intended. I generally find that 'technical' people, being engineers, scientists, or 'hobby' technicians for example, are interested in such stuff and tend to just accumulate snippets of information. Obviously not all will learn everything there is, but F4TCT is an aviation person where things like fuel quality are somewhat important (eg. water in your fuel can freeze at altitude - which can be embarrassing), so I was a little surprised he thought there was just 'diesel'.


Importing petrol makes perfect sense if you don't extract enough crude locally to refine to meet all your own needs. A 'mega' refinery will usually do the job cheaper than a small local one and if you have to ship liquid in anyway why not ship refined fuel instead of crude?

to be fair,


we use avgas, 100LL its 2 a litre for a reason. its blue and we check for water at the first flight of the day.


the newer engines can use normal mogas although the higher octane the better.


the very rare diesel aircraft use jet a1 - different ball game all together.

Although, I'm quite late in this thread, I just wanted to show and ask something...although this is clearly not scientific, if you search for 'Tesco contaminated fuels' or 'Sainsbury's contaminated fuels' into Yahoo!, see how many news stories there are. Then search for Texaco or Gulf contaminated fuels and see how many news stories there are...Fair enough the media might be slightly biased but still, if they all fill from the same tank, why are the higher end forecourts not getting these problems reported (not meant sarcastically)?  :-)

exactly, its the 'ends' of production going to the supermarkets...

seems to be a huge divide on opinion on the matter - naturally i guess.

Hi all
After reading all of this over the last few weeks I have started to use shell and BP instead of the supermarkets  , for me its easier spending the  extra pound at the petrol station instead of possibly hundreds at the garage,  not sure if I'm getting more mpg's yet but time will tell.

Dan , I hope you get it all  sorted out and you get something back from the supermarket....

I've never bothered worrying about petrol types and mpg too much because the biggest variable in my driving is me.

Some days, the traffic is a bit busy so I drive slow and don't even bother trying to fight my way through to save a bit of time - probably good mpg.

Other days, I get a clear road so I 'enjoy' driving a bit more - probably much worse mpg.

As this varies over the time it takes to empty a tankful, then I can't accurately predict my 'target' mpg.

If I want good overall mpg, I should buy a car with a little engine.

I thought jet a1 was basically kerosene not diesel and used in jet engines.

In our part of Australia I have only ever seen 2 kinds of diesel, truck and car. As far as I can tell the only difference is in the size of the nozzle, the truck pumps are usually fast flow, so therefore a bigger nozzle and hose. My 4WD can accept either so I just go to the first available pump. If there is a difference between the 2 types I have not noticed it, as my Mitsubishi Pajero performs just as well on either, with no variation in economy.


However, once you get into the cold areas of Australia, such as the Snowy Mountains and snowfields, there is a winter diesel fuel available. When I was coach driving we would always fill with the winter fuel in those areas to aid cold starting.

you should always put in the grade of petrol or diesel that's either in your owners manual or on the filler flap I have been an owner of a Nissan 350Z for some years the car has only ever been ran on high octane petrol like Shell SuperV or Tesco99 members on our forum have had engine failures like burnt out valves etc just running them on a lower grade only it's a fact. I also drive a BMW 330D again I use Diesel Super from petrol stations for the extra pence at a fill up its worth it plus you will get better running and performance with the right grade fuel.
On another note my friend works for Fina at Buncedfield refinery where they had the huge fire some years ago he tells me all the petrol and diesel is the same for all stations around the country Morrisons,Tesco and Sainsbury fuel comes from the same tankers that shell,BP and Murco etc get theirs.  O0

 {-) Many moons ago an old mate of mine who fancied himself to be a bit of a car mechanic had an old Vauxhall Cresta with a knackered engine so he goes to the breakers yard and buys a good one for a fiver(I am talking 50 years ago) after a bit of a struggle we manage to get the engine into the boot of the Cresta, on the way home we came across some road works with a big ramp which he did not see,as we go over the ramp there is a big bang followed by a crunch so we get out of the car to have a look, the engine and the floor of the boot were in the middle of the road,suffered with a wee bit of rust those Cresta's well I mean you can't laugh in those situations can you,Ray. {-) {-) {-) {-)

I had an escort we did that with, we had parts from 3 engines, it had a 1600 rad, a 1300 block, a 1100 head and various other bits to get the engine running, I ran that car for over a year, and sold it to a mate who took it down to cornwall on holiday, the only bit that let him down was the wiper that fell off.
