I normally use Esso unleaded from my local garage,last weekend in Plymouth I pulled in to an Esso garage and was given the choice of unleaded or Esso Supreme,there was a price difference,79.9 for normal and 90.9 for supreme,gave the car a treat and filled with the more expensive,does the panel think this is worthwhile should it become available at my local garage and is this the same price differentual as the Optimax which is often mentioned?.

Would have to be good - thats nearly 50p a gallon more expensive.
|
|
I don't think so, that's over half as much again on the nett price (pre-tax)
|
11p per litre. 4.54 litres in a gallon. 11p x 4.54 = 44.94pence. Sorry I was so innaccurate!! :)
|
Why bother converting anyway? Everyone knows the price of a litre of petrol as they see it every day. What relevance is a gallon?

Boycott shoddy build and reliability.

True, but we do work out our averages in miles per gallon.
|
|

Because I'm very old and still think in terms of miles per gallon. Presume you think in terms of litres per 100 kilometres. By the way, I work about 5 miles from home and my speedo reads in MPH and miles. Unless yours read in Kilometres you have to convert to get MPG. That's why I find it easier to think in terms of cost of petrol in MPG. 50p per gallon is about a penny per mile added to my costs.
Anyway, I'm off for a pint.
|
i'll join you for that PINT.the pub is only a MILE walk.
and if you get there 1st,i'll have 1/6 gill of vodka.
|
|
you can walk that mile and have that pint but you cant have 1/6 gill of vodka it's sold in ml measures these days unfortunately...cheers...keo

Sorry, got a bit confused their (old age) - meant to say that "unless your car reads in kilometres you will have to convert to get litres per 100 kilometres"
So, forget the pint, I'm off for another 125 millilitres of wine. Or a glass to us oldies.
|
|
thats a small glass - i prefer 564 millilitres!
|
|
Or perhaps 568 millilitres if you wanted a full pint! ;-)

I dont think its really worth the extra 10p a litre wotever it is etc... do you know the octane rating? Shell optimax is 98 Ron. Is just sounds a bit OTT to me. But then someone must get some improvements out of it, i mean i use optimax in my ka & it improves the acceleration quite a bit!
--
Its not what you drive, its how you drive it! :-)
|
Thanks but no thanks for replies,I know it is about 50p agallon more expensive,the question was is it comparable to Shell Optimax and does Shell have the same price increase over its ordinary unleaded.

I find that both supreme and optimax give me both fresh breath and a glossy coat, though of course it could all be a marketing exercise and the benefits all be in my head...
|
Not sure how relevant it is, but if you run a diesel try the Shell diesel extra. Same price as the regular stuff but has made a huge difference to my car. Only sound I hear at motorway speeds now is the whistle of the turbo and the car is noticably more responsive.
Having never driven a petrol I can't say what difference to expect, but a read of the manual of my dad's Astra lead me to believe that the engine is specifically designed for a fuel octane and won't gain any improvement from a different one. There's a way of setting the engine to different octanes IIRC.

Your Turbo is whistling? oh dear oh dear (sucks air in through teeth)
|
|
|

Optimax (which is what I use) tends to be between 4 and 6p per litre more than the standard unleaded, which is bearable. 11p extra per litre for the Esso seems pretty steep.
Not sure about octane rating but I'd be surprised if it's as high as Optimax - AFAIK that's the only generally available 98-octane unleaded in this country. All the other supers tend to be around 97.
|
Meh. It's whistled ever since I owned the car and it's very quiet, only just audible from the driver's seat when on boost. Can't imagine it has any effect on performance, as the car is extremely nippy anyway.
Hasn't been picked up on 3 services, either.
|
used to use optimax in the scoob.
yes it made a big difference.
ran smoother, better mpg, could get 155 miles to £40.
now selling it so i just fill up with sainsburys stuff at 76.9
think optimax was 88.9?
now get 100miles to £30
car hesitates, and dosent pull cleanly all thru rev range, on 76.9 juice.

Thanks for that information paul,I have no Shell garage within 30 miles of where I live so could not make a compsrision,I have not noticed any difference so will give it a miss next time I,m in Plymouth.

Back to where ndw started: has anyone actually tried Esso Supreme?
HJ

so what is wrong with a whistling turbo,,,,,,,,,,
dont dump valves whistle????
that whistling turbo charged impreza has just thrashed me again :)
|
All the early turbos whistled as they spun up. I find the noise very sexy...
I'll get my coat.

My car requires a high octane fuel as standard 97 . Although it will run on standard rated petrol the diffrerence is very noticable, particularly with the girlie button switched off. I have tried Total Esso BP and Shell, and for me the Optimax gives by far the best performance. All are about equal on mpg.
|
Oh f' goodness' sake!
Optimax (and similar petrol) is not a 'treat' for a car, it is a waste of money unless... you have a high performance car that requires a higher octane rating.
Those old enough to remember (most of the BR, according to the age survey) will recall that when 'lead' was taken out of petrol, (about 1990?) cars had to be converted by having their ignition retarded, as unleaded had a lower octane rating.
Some high performance cars struggled on the lower (95 - standard unleaded) octane rated petrol, and 'super unleaded' was sold, which was 98.
Somehow or other, in the UK, super unleaded ceased to be sold widely. It always has been sold on the continent, where going into a petrol station has been like choosing a malt whiskey in a good bar. I think the Frenchies have finally stopped selling 2*!
Then Shell invented Optimax. Which exists to help our glorious mods to dress better (one of them once told me.) And marketed it as a super duper present to give to any old car.
But I'm afraid that a 1.1 Formule E Polo will obtain no benefit whatsoever from it. That 20v Audi Coupe (see other thread) will benefit.
Look in your car handbook. If it asks you for 98 petrol, then use Optimax. If it asks you for 95, use supermarket.
If you want to 'give your car a treat' then send me the price difference & I'll say a prayer for it. Or buy it some fluffy dice. But don't waste your money on Optimax - unless your handbook says so.
And all different brands of petrol are produced to the relevant BS. And why anybody should ask you whether you'd 'TRIED' Esso Supreme is beyond me. And, and and...
Anybody who has had any involvement in statistical tests will know that a random punter trying a different brand of petrol in his car does not constitute 'evidence' of one brand's being better than another. Double blind testing, in laboratory conditions, is what is called for. Sorry.
EVEN my brother, who is a very bright chemical engineer of very high capability uses Optimax in his downmarket Astra, as he has fallen for the marketing spiel. I could not get him to justify his choice from scientific principles.
It's 7.15 on a Friday night and I'm still ranting about Optimax et al. Better get off to the pub!

300 miles, 240 motorway 60 two laners and towns. 4 adults and their luggage. Elapsed time exactly 4 hours. Brim to brim consumption 40mpg. Fuel Shell Optimax. Car a bog ordinary ex-rental Mondeo.
But I do want to know if any Backroomers have had good results from Esso Supreme.
HJ

Oh HJ.
Why should anybody have a 'good' result from Esso Supreme ( rated 97) rather than from Supermarket 97. And would you believe that the 'good result' from a single tankful has any statistical significance whatsoever?
300 miles, 40 mpg = 7.5 gallons = 36 litres.
Brim to brim is a shockingly inefficient way of measuring petrol consumption accurately. Could easily be a couple of litres out or more. On a run that is only 36 litres long, this is a 5% or more difference, or a couple or more mpg.
Do you believe that the mpg-age would have been lower running on Supermarket Finest?
IIRC Optimax claims that you have to run several tanks through before you get any benefit, which makes a single Optimax filling - as described above - remarkably insignificant.
Is 40mpg remarkable for a repmobile? I think not! Optimax or not.

I've got Supreme in my car at moment, was 85.9p a litre as opposed to 80.9p for the regular stuff. As for a noticeable difference? NO
|
All fuel suppliers are party to an agreement whereby local shortfalls are made up by other suppliers in return for the same favour as and when. The fuel in your local Esso station could be that awful supermarket near water stuff and the fuel in your local Tesco's could be that superduper car enhancing Esso mega fuel. Now IF there was any significant difference do you think this would be the case? The legal implications alone would put a stop to it.
Optimax is outside this agreemnet and I don't know but would guess Supreme is also but as said above if you car is designed to run on 'normal' fuel you will gain no advantage anyway.

Mapmaker did not work out the average speed of that Mondeo.

Humble apologies to backroomers for the wrong information in my previous post.
Visited Plymouth again last weekend and found the correct price of Esso Supreme is 86.9/litre not 89.9 and six pence over their standard unleaded which was 79.9/litre.For those who queried its ron rating it is 97ron.
My local Esso station now has one pump seving this so I may use it as my mileage is only about 4000 per year if it is as kind to engines as Honest John says Optimax is (which I cant get locally)snswers welcome.
