hi chaps.
is there any advantage to using high octane fuel in an omega? :)

No.

You can use V Power to good effect...
But...
It costs more, although you get slightly more miles from a tank and the car will feel more responsive...
Net benefit is zero though, as Nick so succinctly put it ;)
-

How do you suppose that works?
-
haven't a clue just what I heard ;D
so v power it is then :y

V Power will cost you an extra £2-3. You will get an extra £2-3 of mileage from it. Ergo, you might as well stick to regular unleaded ;)
-
is v.power not a cleaner burning fuel..there fore cleaner moving engine parts :-\ :-\
-
Might as well just put in V Power... Every little helps. I use V Power if that particular pump is clear if not i'll just use standard Shell. But I've only used Shell whether that's standard or V Power the past 3 years with the V6, I used to put anything in the 2.2 though I didn't notice any difference in that car... In the V6 i noticed i was getting less miles with other fuel garages. Could well be a placebo effect but i'll be sticking with Shell fuel for the foreseeable future regardless.
-
Basically, gives a bigger bang, therefore helps increase power out put, not really noticeable on an un-tuned road car, the only real gain is the higher burn,and higher temps is it helps burn off residues in the exhaust side, and cats. Best used for a week before mot day,.
-
Always use BP ultimate since I bought the mig in 2010 & still use it in the Merc.
-
think the compression ratio is 10:1 on the 2.2 so yes you'll benefit from higher octane petrol - knock sensors will allow the ignition to advance, more power, more mpg. on the 2.5 V6 (also 10:1) i used to get 10% more mpg with super unleaded, tested on several journeys on the same stretch of motorway on cruise control.
i haven't tested the 2.6 i suspect the gains aren't as much as CR is lower.
-
Higher octane fuel doesn't give a 'bigger bang' or help increase power output. If petrol is identified as higher octane, it means that of the many hydrocarbons of which it is composed, octane is there in higher proportions. As octane is more stable than other hydrocarbons, this results in a more stable fuel that is less likely to knock. Using the so called premium or 'high octane' fuel in an engine designed for high performance and/or turboed engine will allow that engine to function as intended, without knocking, it won't make a bigger bang or make more bhp than stated, nor will it do that in an engine that is capable of running on regular fuel. Ask yourself how many standard road cars really need high octane fuel!
-
The (very mild) benefit in (modern) 91/95RON cars is the ignition will advance more before the knock sensors drag it back.
This will have a (minor) impact on economy and responsiveness.
-
When I stick the posh fuel in the GS, I can really feel the difference. Smoother, more power :D :D
Now I've started using bike for work again, I'm going to stick a tank of the good stuff in. As post winter slumber just been getting used to riding it again. As I've also just fitted muffs!
Never really feel a difference in the car, don't really feel it's worth it over a tank of 60L.

it allows the ignition to run further advanced without knock this does give a bit more power and economy. only works in cars which have variable ignition timing controlled by knock sensors (which must be almost all by now) and which have a decent CR. hence 10% better mpg on the 2.5 v6 (CR 10:1). super unleaded is rarely 10% more expensive than ordinary unleaded.

It's not 10% better though...

Not sure if Shell still do this but keep an eye out for Shell Garages that are closed for Refurbishment, then contact Customer Services, they normally nominate another Shell Garage thats closest and send you a book of Vouchers to use in the adjacent Garage, this can include 10p off per litre and sometimes promotes there V Power for the same price as the normal stuff included within the 10p off. :y
Cant remember if you need to be on the Shell Drivers Card Scheme or not for this, :-\

I've tried higher octane petrol on everything I've owned(knackered 1.7 astravan excluded!) recently, and the only one that had a noticeable difference was my 1.8GDI Legnum. That had a slight improvement in power when heavily loaded; it got about 4 tankfuls in France.
The only change it makes to the Omega is a fillup costs more.

Piss off.
I speak as I find and have tried V power in the following cars...
'95 N 1.4 Peugeot 106
'51 3.2 Omega manual
'55 1.9 Vectra 150 cdti
'07 1.9 Seat Altea XL tdi
'54 3.2 Omega manual
'00 2.0 Omega manual
'55 1.8 Vectra C saloon
'55 1.8 Vectra C hatch
'58 1.8 Vectra C hatch
'03 3.2 Omega manual
'63 2.0 Insignia 130cdti
'03 2.2 Omega auto
'11 2.2 Merc E class Blue efficiency diesel auto
'61 2.0 Insignia 160 cdti 4x4
'03 3.2 Omega auto
If that isn't a wide enough test pool, then I don't know what is... on every single car, the net result was zero, ie the extra cost was balanced by a slight increase in mpg, resulting in the same pence per mile.
-
A fresh air filter, Wynns fuel treatment, a tank or two of V power and a good thrashing are useful for keeping v6 cat codes at bay, and for clearing the system through immediately prior to an MoT. The only other reason for using it is to collect double/triple points :y

i don't know why you're getting so worked up about this. anyone can post a long list of cars they have driven but the proper test is quite easy to do especially if you drive to work on a motorway that isn't too busy (as i used to do):
* choose a set distance eg between 2 or three junctions
* make sure your tank is fully either unleaded or super unleaded
* set cruise control
* reset fully your average mpg on the display
* drive the distance at the cruise speed and write down the final mpg figure.
tested half a dozen times i was getting about 10% more mpg with super on the 2.5 V6, that's my experience.
hopefully oof is about people sharing their experiences not about keyboard warriors telling people to piss off
-
I have always used a higher grade fuel since 2010 ,not bothered about MPG if I was I'd buy a small vehicle, the cars have always performed well & sailed through the emissions part of the MOT, for a few pence I am happy with that.
-
I responded that way as your implication was that I was merely 'gobbing off'... Your patronising reaction does little to change that...
Collectively I have done nigh on 450K miles in those cars, on a variety of journey types including stop start town work and non stop long distance. Consistently the results are the same... The pence per mile cost remains constant regardless of the type of fuel used.
Simples.

And what exactly is that going to prove? So you have driven say 15 miles on a handful of occasions and made a comparison? ;D
Unless you have weather reports for the days which you carried out these scientific tests and can prove the temperature and air pressure were identical, I'll not believe a word of it.
I'm an advocate of Higher Octane fuels in vehicles where the ECU can make use of it. The Omega..... won't. It simply cannot advance/retard the ignition far enough to make a difference, and as I've said before, nowhere near 10%.
I'd also question the accuracy of the MID below ~100 miles. Mine used to vary wildly after a reset (3x Omega Elites, 2x 3.0 and 1x 3.2).
I can actually see how far the ECU has advanced the timing on my car, and 'Super' fuels do make a noticeable difference in performance. As for MPG, no idea..... I don't like crying, so I don't look at it too often.
-

you're not serious are you? ;D
omg i think you are :o
just do the tests a handful of times you'll find the results are remarkably consistent.

:y :y
I'm not bothered about the extra pence for the super unleaded because it does run better and I can get a slightly better return on the MPG (more noticeable on motorway), my Omega can take and make the benefits of 98 so why not use it.

I don't normally post if I disagree with something or someone on here, I usually ignore it, but on this occasion I feel in a position to comment. ::)
I travel to a cottage in Cornwall several times a year, using the exact same route each time, in the exact same car and with the same grade of fuel. Due to speed restrictions (my wife), I travel on cruise most of the way there, so my speed on each journey is quite consistent. I always travel in the early hours so traffic does not affect my constant speed but my fuel consumption varies each time. On the same 290 mile journey my fuel usage varies from just over a quarter of a tank to almost half a tank. The weather does make that much difference. :y
How do I calculate anything from this? :-\

A brief glance through this article ought to demonstrate how overly-simplistic that approach is...http://blog.caranddriver.com/why-your-trip-computer-isnt-giving-accurate-mpg-readings-and-how-to-fix-it/ (http://blog.caranddriver.com/why-your-trip-computer-isnt-giving-accurate-mpg-readings-and-how-to-fix-it/)
There are far too many variables to work it out in the real world. Given plastic tanks expand/contract depending on temperature, even brim to brim is far from an accurate method.
Instinctively I think that unless your car has been mapped for higher octane fuel - and hence will knock its ar$e off on 95 Ron it's probably not worth the cost difference. No scientific basis for this though.
In reality I suspect any of the following would have a bigger impact on your mpg:
- unloading all the accumulated crap in the car
- driver losing a couple of pounds
- correctly inflating tyres
-
As has been said, not much point in using premium fuels in an Omega but the power of marketing and the placebo effect is significant. ;)
-
The weather does make a difference to the running.
-
results for my 2.6v6 manual, super unleaded, 60mph on cruise, same 5 miles of motorway, different days (months even)
38.8mpg
39.3mpg
38.5mpg
38.8mpg
try it.
incidentally i've also tested the MID 'range' function on the mig, twice on the 2.6 and twice on the 2.5. both cars figures were accurate to a mile.
not so easy to try, be safe.
-
Definitely snakeoil...
Done 240 miles today on a brimmed from empty tank of V Power... mostly motorway and mostly with cruise on and managed a whole 23 mpg ;D
-
not snake oil, octane is a fundamental part of petrol chemistry.

Good read. So what's your point? I don't see anything in the Millbrook report which suggest anything like a 10% increase in fuel economy. Please, prey tell! ::)
As for the Shell Nitro vPower+ RocketFuel Titanium CarbonFibre edition report, sponsored by Shell (which doesn't state any firm figures on fuel economy), again.... what's your point? ;D
YES, IT WILL HELP ENGINES WHICH ARE DESIGNED (OR MAPPED) FOR IT TO WORK WITH. IN AN OMEGA, IT WILL NOT. Simples! :)

Fit a rubber crankshaft, increased compression as the revs build up = more power = better mpg :y

TurboMags are what you need instant 15 to 25% increase to MPG, works on Petrol, Diesel and LPG. Gives High octane performance with lower octane fuel, read the tech spec on the sellers page, proven technology.
I reckon its only a question of time before Car Manufactures catch on to this and start fitting them as standard. ;D

Ooo, now that is interesting, which programme are you with? I've managed to amass 190k of Miles and More in the last 3 yrs. hoping to hit 220k by next spring to take swmbo and I to the US business class so always keen to build up the miles!

I dont think your get a full tank Nick, If you were to use V Power added to the TurboMags, you would be up there in the Plus 35% extra MPG, A some simple Water Based Mist injection, say another 5%, if you could cool the mist to below 0 Degrees before injection probably another 5%, that gets you up to 45% say, then LPG it, thats 50% savng in MPG compared to Petrol cost, your nearly there. :y

But surely if we combine all of these with the instant increase that the internet adds(increase=gullible% x √[stupidity/optimism]π) I'll get within 97.846902645% of my goal? Surely?
And I love the idea of water just below zero degrees: some oppswit somewhere is bound to buy into snow injection ! We are rich beyond any dreams of avarice and will never need to work again
-
The Omega MIDs/GIDs/CIDs are pretty accurate on everything but range - try a brim to brim manual calculation, resetting FC at same time, to work out average MPG over a tank. You will find it bloody close. Thus it figures that >7.1mpg instantaneous readings are accurate (FC appears so use <7.1mpg figures in overall calculations, but never displays less than this).
The MIDs actually have an adjustment for MPG, a feature removed from later developed GIDs/CIDs as deemed not required.
If your FC is properly set for your car configuration, and is inaccurate, you have an issue with engine and/or sensors.

Have a Shell points card, when you register it and get an account, you can choose how you collect the points... I simply went with the avios option :y
Apparently you accumulate points from the get go, but they don't show on the account for a year, so not sure how quickly they build up :-\

Thank you, but I was going to use bumper mounted windmills to enable any Reliant engine to replace Scania's wimpy diesels.

Joking aside, it has been suggested that a big block Chevvy lump running on Lpg and fitted with a suitable hi torque gearbox would be at least as economical as an equivalent power commercial diesel lump, and greener too without the need to add piss to every tank...
Shell would probably sell enough fart gas to pay for another infomercial about it :-X

Apparently you accumulate points from the get go, but they don't show on the account for a year, so not sure how quickly they build up :-\
I trust you also have an AirMiles Amex and pay with that at the same time? :y

Shell clearly didn't have anything to do with that piece... ::)
If it helps you sleep, you carry on... I will continue to buy it as long as I get triple airmiles :-X

I don't, for reasons beyond my control, but that's not to say the thought hasn't crossed my mind :y
That said, by the time I can afford to go anywhere, I should have enough points to get there ::)

not wading in to this debate. just adding my thoughts...
when I did the 0-60 thread (stop it!) I tried out super unleaded thinking ''oooooh the manual says it is mapped to run on 98 and there must be at least 100 horse power I'm losing by not running the super unleaded'' ::) ;D
however there was literally no improvement in performance. zero. if you want to see how I measured this see the 0-60 thread.
the only things I did notice was that the car seemed to run hotter and there was an audible ticking noise. following that I went back to the 95.
fuel economy. don't care, not looked in to it :y
-
Webby; not (really not) wanting to dredge up your 0-60 thread, but do omegas "learn" the fuel?
By that I mean that iirc Saabs adjust their mapping slightly dependent on the fuel you feed them so the first tank of Super Juice (TM) doesn't do much to alter performance but allegedly the car learns how to burn it better so future tanks show improvement.
Just to add: I suspect the "learning" thing came off a forum too so not sure if it's dangle berries or not. :D

The Omega ECUs have knock retard, in that they retard the ignition if fuel quality is so poor that the engine starts knocking. They don't advance the timing from the mapped values. It's simply a measure to protect the engine from "weasel pee". I've never seen a healthy Omega where knock retard has been anything other than zero, regardless of fuel.

Ooh... This has been exciting! Handbags at dawn? :-X ::)
My experiences are that the V Power/Ultimate type fuels make no difference on standard road cars. Used to use it in the bike, which was noticeably different.
Better to stick a branded cleaner through periodically IMHO :y

This is on the flat, cruise control on and looks like the air-con is on as well :y
Always get good return.
Manchester to Dagenham on same tank &
Manchester to Swansea also on a tank not bad going that.

;D I promise I wont.................... 'til the right time! 8) :o 8) :o
no idea about learning mate to be honest. I didn't like the knocking noise it seemed to emanate so got it out of there sharpish :y

The timing is already advanced, it is designed to retard it with knock control when required and will return to the highest advance value it's setup for until reaching a knock value. It's constantly in a yo-yo effect but always trying to reach the highest advance it can, on the 3.0 it will handle advance for 98 unleaded.
-
:y agree with that
as does the owners manual page 216
"Octane requirement 2.6V6 and 3.2V6
unleaded 95, 98(2)
2) Knock control system automatically adjusts ignition timing according to type of fuel used (octane number)."
apols i was out on the CR earlier it is not 10:1 on the 2.5 and 3.0 it is 10.8:1 (10:1 on the 2.6 and 3.2)
