It's pretty well known on here that you shouldn't use Ultimate. T99 or V Power are much better.

Your losing 2 octane, which can incer DET. Stick a full tank off tesco 99 or Vpower.

Just curious as to why you would ask the question ?,,are you already using it ?. If so have a read of the link below:

hi midnight, you were giving me some advice the other night regarding my car not feeling as good as when i first picked it up, ever since the first time i put fuel in it and everytime since it has always been bp ultimate as i have a bp at the end of my street , ive also bought a standard re circ valve as you suggested,

could the choice of fuel be giving me some grief

i also have a tesco very close to me aswell for tesco 99

cheers

I'll put this in plain English:
BP Ultimate is sh*t!
I hate Ultimate with a passion, I've had less det using Esso 95.

Use V-Power or Tesco 99.

I just got my wrx on saturday, and the guy told my he had it remapped with a piggyback ECU (polas or something) to use 97 ron, so I just use sainsburys super. I shouldn't have any issues if it has been mapped to 97 should I?

I cant make it any plainer than : put the best fuel that you can afford in your car,higher octane means better combustion in the cylinders = more power + more efficiecy . You dont put castrol gtx in your engine when you do an oil change do you ? ,you can do ,your car will run ,but it wont thank you for it,and the oil will break down 3 x as quick as a really good synthetic oil imho. If you put the best fuel you can afford in your car and the engine does go bang ,then at least you have piece of mind that you have done your best to try to maintain your enginre -rather than neglect

Vpower has been released fo nearly 10 years ago i think

Ah ok, so even though it's mapped for 97RON, I won't have any ill effects if I were to use VPower or more likely (due to shells distance from me) Tesco 99RON?

rezaP1

There should really be some kind of massive notice advising folks to NOT use Ultimate or anything really other than V-Power, or Tesco 99

K1985, using a higher RON will not cause issues, but you will not be benefiting from any of the gains associated with running better fuel ( 99 RON ) unless you have your map tweaked. So best thing to do is get the ecu mapped for Shell or Tesco ... funds allowing of course

I had my car mapped on total su 97 ron, couldn't be bothered with the small gain I will get with sticking with 99 ron, I will probably use tesco 99 a lot of the time but at least I know if I get stuck I can just fill up with 97.

I have had both my last 2 cars mapped on tesco 99, and that is all that I put in with exception to shell 99 occasionally . There would be no I'll effects if I had to fill up/ top up with superunleaded 97 fuel ,and the car would still run ok as the ecu resets for the lower octane fuel, but I would have the sense not to be giving it stacks & hitting full boost on the lower octane stuff as my car was mapped on 99 Ron fuel.

Steven had the hatchback mapped by Paul on Ultishit.

100% Agreed there.


In order of preference:

1. vpower
2. momentum (tesco99)

and if stuck...

3. total excellium
4. esso super

and if desperate only to get to the next proper fuel stop

5. bp ultimate
6. other supermarkets super

bigsinky

guys this is all a load of *****. What do you think us guys in Northern Ireland do? We dont get Vpower, momentum, excellum or esso super. we have bp ultimate or tesco/sainsbury super thats it and our cars are mapped to run on 97octane fuel with no problems.

all this sh1te about causing det etc is a load of *****. if the car is mapped safely for the fuel that is used most often then there should be no problems. minimum 97 ron. having said that were uk cars not first run on 95ron?

You can call bull**** all you want. Every time I've had to put ultimate in it's been det central. I've had less det with esso 95 than I have with ultimate. I've no doubt it will be fine on standardish cars. My issues were on cars with 400+ with aftermarket ecus. Obviously if your mapped for ultimate then you won't have issues but you'll be down on power. I don't give a toss what you put in your car but I wouldn't even put bp ultimate in mine to get me to a shell garage. It's f*cking awful stuff.

You know me Duncan I'm not afraid of speaking my mind lol

bigsinky

i don't doubt it for one minute. we dont like it over here either.

Standards cars should be fine but more often than not we are having to use octane booster

A completely different kettle of fish. they usually have a load of ignition advance which you hope your aftermarket ecu will retard at the first sign of det.


A ******* shed load, but then thats what methanol is for

Unfortunately Daz as long as the main petrol suppliers in NI continue to say the market is not big enough in NI for them to ship the higher octane stuff, we are left with BP Ultimate and supermarket SUL

I tend to use sainsburys super unleaded or Vpower, i cant actually notice any difference between them - However, my car is only a WRX and is totally standard. If it was tuned up or mapped on a different fuel then id be more selective. Think this is an important note to remember!

Well my local is a BP, and Simon (JGM) mapped it with that in. I will admit that mine doesn't run as well on the BPee... I haven't seen higher knock levels in particular, but the car feels as if the ecu is pulling some timing.

All IMHO.

P.S. Luckily I'm 1 mile from a Shell garage at work...

dazdavies

iTrader: (22)

I do feel for you if that's all you can get but like you said methanol will sort it.

My point is aimed at cars that have been mapped on tesco 99 or V-power. Some people wrongly assume that BP ulimate is a comparable product. Although BP would have you believe it is, it isn't. A car mapped with V-power will be put at risk if you run it a hard on BP ultimate. It's nowhere near as good as vpower.

The only way you're going to be completely safe on the stuff is if your car has been specifically mapped for it. Mine isn't so I'm staying well clear of the stuff.

dynamix

If it has been mapped on the BP it shouldnt see any det activity and it shouldnt be retarding ignition. Yhe ignition will be lower though purely by nature that that is what has been put in the map to compensate for the (VERY) poor fuel quality and to get the best out of it safely.

If you only live a mile from shell why not get it mapped for the best fuel around?

On a recent tuned wrx I did with a VF35, STi tmic, 550s etc (normal suite of mods) ... the difference between the vpower map and normal SUL was 26bhp !! Why not run the best fuel. Even in standard form they prefer it.

1 mile from work Duncan...

In case I can't get any out in the deepest darkest crevices of the North Pennines...

P.S. I add octane booster to whatever I run it on, and she flies once the ambient is down below 15 degrees

vpower feels so much better than SUL 100 times better than the BP

Hi, i have just joined this forum and alarm bells are ringn cuz ov bp ultimate petrol i have a wrx sti 97 jap import and i always ran it on it i fout the car always run better on it.
