I have a tesco 100 yards from my office and im tempted to start filling up with their momentum 99 RON rather than treking 10 miles to my nearest shell for V Power. Has anyone had any experince of both and if so is there a massive difference.

Also the clubcard factor comes into play - i.e. Channel crossing vouchers for trips to the ring

your thoughts would be appreciated? Cheers

 

Mine was mapped for it, never had any issues really

 

its an ongoign raging argument lol

general info seems to be vpower is 99ron with adatives, momentum is 99ron and just a rebrand of tesco99.

although i did notice all the press info released about it was only ever against 97 and 95 petrol not vpower.

personaly i use vpowers due to some bad stories on tesco99 and being mapped for vpower

 

This one has been done a few times and if you hit the search button and type in tesco 99,it should give you a few post. Personally i use 99 from tesco,and have done for the last 5 years with no probs ,but i also use v power as well,it just depends where i am when it comes to filling up.Tesco has the bonus of the clubcard as you mention where as the shell drivers club is crap imho

 

I used to use the Tesco stuff, but supplies were VERY unreliable and Tesco couldn't give a flying ****
NEVER known both our local Shell stations to run out of V-Power at once

 

Mines mapped for V power but regularly use Momentum as it's now called - no issues with either, Clubcard a bonus and the V=power club is glossy but crap

 

Sorry fella should have done a search before posting.. Opps... Note to self search is my friend

 

I have no choice at the moment they have knocked the shell garage by me down, so using momentum 99 on a jdm MY05 std jap map no problems at all, my car can't tell the difference between the 2.

 

i always use (tesco) it and never had any problems in either of my subaru's

 

mine was mapped for v-power but on occasions i used to put tesco in it, on my weekly 350 round trip i used to find v power more responsive but tesco slightly better on the mpg

imho

 

I couldn't agree with this more, on many occasions I've been to tesco petrol stations and they have had no 99. There is a shell much closer to me than a tesco so I usually use that anyway but I've never noticed a real difference between the two. It may well make a big difference in a heavily tuned car though

 

i have a small tesco 5 mins from house and they always seem to have it in, plus its mapped for it on this scoob but have used it in others for last 2 years or so.

happy with it.

 

safest bet is stick to what your car has been mapped on, mine has been mapped on v power thats all i use, I personally dont trust any supermarket fuel.

 

I tried both when I bought the car a couple of months ago, one after the other obviously as I had no idea what it was mapped to. Mine prefers Tesco, but it wouldnt have mattered either way - it's all bloomin expensive!

 

mine was mapped for tesco 99, and is usually cheaper so thats what i use, i have tried both and found shell seams to keep the power from a full tank down to empty, (i use a tank full every week) but the tesco tends to "go off" so to speak near to refill time. weird?!

 

both exactly the same albeit apparently very minor diffrences. i use both with no issues. just use whichever is nearest at the time imo

 

For the first five years shell 230 to the tank

The last five and half years 250 to the tank

No problems whatsoever

 

Sorry to be pedantic; but its the additives that makes it 99ron; like any other fuel really as they all contain octane boosters and "cleaning" additive of some form. Its base fuel is likely to be 95RON and the additives bring it up to its marketed 99RON.

For VPower, these additives include Toluene (most fuels contain this), Xylene and Trimethylbenzene (other fuels somtimes use MTBE instead like BP do). Tesco differs in that it uses Ethanol. They are all octane boosters of one form or another, but with different burning properties and energy content.

Inccidentally all fuels contain additives of some form for both octane and to promote cleaner burning (oxygenates). Be it supermarket 95Ron or BP ultimate 102Ron (now discontinued) .

Here's what Vpower has: http://www-static.shell.com/static/a...hellvpower.pdf (page three under additional information, alternative source: http://www.formulastudent.com/Librar...MSDS.sflb.ashx bottom of page one), similar ingredient can be found in other brand and grade fuels. But like all other fuel companies, it refrains from publishing the quanities of each active ingreident, so we can never properly compare it.

Unfortunately what MSDS I found on Momentum or Tesco 99RON just shows the ingredients as "gasoline", which is about as useful as a chocolate fireguard. But its prime oxygenate is Ethanol.

In respects its different ways of achieving the same end objective as cheaply as possible (to maximise profit). To truely compare both fuels we need to know its burn speed, energy content and its stability for both short term and long term storage (i.e how good is it after spending two weeks in your fuel tank).

 

Cracking post mate and very informative. Im going to give Momentum a try for a few tanks and see if it makes a difference.

 

i remember an episode of 5th gear where they tested fuels. i remember Vpower being better than bp's equivalent on the impreza in terms of power and mpg... there was a third petrol they tested but i cant think what it was. was it maybe tesco? cant get on youtube so cant hunt it down.

i personally wouldnt use tesco's though after that fuel hiccup they had a few years back. wasnt something being sold as something else? or something was added that caused disaster?
another reason i wouldnt use tesco is i have Vpower just a mile to the east or a mile to the west.

 

Mine's mapped for V Power and doesn't run as well on Tescos 99. Good for emergencies but that's it.

 

Don't bother; 5th gear are not impartial. Especially when it comes to promoting choice manufacturer's products, as they are sponsored by advertisers and manufacturers. This is why its called commercial television.

Just like the gadget show.

This is where the old style "funded by the tax payer" Top Gear may have been handy.

 

Shame they spend most of their time now doing stupid challenges, making floating cars, droptop people carriers and burning caravans rather than doing proper car reviews and offering good consumer advice.

 

yeah you are being pedantic lol

99 ron with additioanl adatives.

that better?


lol
