Between Esso Supreme Diesel & Esso ordinary diesel, apart from 8p per litre?
The reason I ask is because the place where I normally fill up has had new pumps installed & when I went to fill up on my way home on Friday I just picked up the extra diesel nozzle. It wasn’t until I looked at the display on the pump that I noticed it was a lot dearer.
I asked the chap behind the counter what was so different & all he could tell me was “8pence, Mate”
If I’m not mistaken the supreme diesel doesn’t have as much water content as normal diesel.
Then again I could be wrong.

More additives and a slightly lower cetane rating

Oh,well how much water should there be in diesel and do you think I should add some to keep my engine clean?
Well you could ad a brain then you could possibly become a driver. Then again not.

Add some to keep Esso’s Profits High ! LOL ! (Soon they will add ‘Green’ to the name on the pump ‘Supreme Green Diesel’ with added Lavender to make it smell better, then charge us another 10 p a litre !) oh ! Gullible we are !

Glad to see that you took it as the banter it was.

Indeed!
But with added lavender they would call it ‘Supreme Blue Diesel’,made to help you relax behind the wheel

Ahhh Nice !
Famous lines from Apocalypse Now-
Kilgore: I love the smell of ‘Diesel’ in the morning. You know, one time we had a hill bombed, for 12 hours. When it was all over, I walked up. We didn’t find one of ‘em, not one stinkin’ ■■■■ body. The smell, you know that gasoline smell, the whole hill. Smelled like…‘Lavender Infused Diesel’ Someday this war’s gonna end…(then all the Oil Companies will be out of business !) (I added that bit !) LOL !

Actually, the better the fuel, the HIGHER the cetane rating.
My camper (ex library truck) runs on it’s weight limit or very close and although a TK330engine (non turbo) is hardly cutting edge technology, it does give some interesting results on which fuel works best. If I buy from a typical haulier or supermarket cheapo stuff, it runs like crap, no pulling power and every motorway hill will be at least one down-change. Premium brand standard fuel is noticeably better with better pulling power and as a result, far better mpg. On it’s own it will improve from 15 to about 17+ mpg, however, the extra oomph allows me to stuck behind a truck easily and use his slipstream and typically achieve 20mpg. (and you don’t have to be right up the rear for this officer). The ‘extra’ type fuels made a slight improvement again although I haven’t been able to do a proper mpg figure.
Incidentally, the highest octane super derv used to be RIX bio-diesel. Many of the truck racers used to use this whenever possible.
And onto petrol, the really cheapo petrol stations (not the supermarkets, the small independent chains) have standard un-leaded that is so poor in burn control, some of the high performance 2 strokes (RS125 etc) are regular victims of seizures when they use it.
My personal choice is to always find a premium brand station that price fights a supermarket. Luckily, in my home town we have a shell station opposite Tesco. Happy days…
Not to be picky deisel is cetane which you want lower but not to low and petrol is octane witch you want higher but my engineering qualification could be wrong
Lol, pwned.
I think it’s worth putting a tank of the ■■■■ stuff in once every six months or so just so these super additives can have a clean up.
I used to do a regular run to Barcelona in a lwb Sprinter. Cheap supermarket fuel = 450 miles (give or take) per tankfull, super duper fuel = 550 miles per tank. Tbh I never worked out the cost versus extra mileage benefit, but I can say it pulled loads better and “felt” better through the seat of my pants on the expensive fuel.

Yep, it is wrong. Put it down to memory loss through sniffing too much cetane (or would that be not enough sniffing )
Following is a list cetane numbers varying grades and types of compression ignition diesel fuels:
Regular diesel–48
Premium diesel–55
Biodiesel (B100)–55
Biodiesel blend (B20)–50
Synthetic diesel–55

Un-owned I believe…
don’t know any tekknikal stuff, …but I have noticed that both petrol and diesel smell different to what they did years ago. 
is it what is now “put in” or what is no longer “put in” ■■?
In short, the higher the cetane number the more easily the fuel will combust in a compression setting (such as a diesel engine). The characteristic diesel “knock” occurs when the first portion of fuel that has been injected into the cylinder suddenly ignites after an initial delay (once ignition occurs, all the remaining fuel burns smoothly as it leaves the injector nozzle). Minimizing this delay results in less unburned fuel in the cylinder at the beginning and less intense knock. Therefore higher-cetane fuel usually causes an engine to run more smoothly and quietly. This does not necessarily translate into greater efficiency, although it may in certain engines. So depends on your aplocation if your in a old truck or car normal fuel is better but modern trucks which inject 6 times per compression stroke use higher
