I mainly use Shell V-power, one - because I have heard it is the best and two - because i have a shell card!

I also have used Tesco ultra or what ever it is called, the 99 octane one and this seems to be just as good as the shell!

I have heard that Bp ultimate is spoze to be good and that is what ford recoment with all new cars now isnt it?

What are your views?

Shell V-power is said to have the highest octane rating (tested independently) at the pump but use what ever fuel your car is mapped to.

I use Tesco 99 because of the Clubcard points

V-Power was the only fuel I ever used in the Cossie - when out at the 'Ring, I used their super high octane stuff (I think it was 102 ron at the station in Adenau) - the engine seemed to love it

Now tho, I just use regular Shell in the 540i - again, I have a shell card - V-power club member too from my cossie owning days

In the escort - anything remotely diesel like that burns LOL

in the cossie I use V-Power whenever possible, but more often than not BP Ultimate as I pass a BP station on the way to work

There's been a few comparative tests between the different 'Super Unleaded' makes in EVO mag and also Fast Ford ( or Performance Ford ) mag.

They've used different test mules on each occasion and the results have varied as to what gave the most power on straight dyno figures and also on what the car 'felt' best with.
Tesco 99 has done well in one test, V-power did best in another, BP Ultimate made the car feel very responsive etc.......

So it would seem hard to say definitively for your particular engine - if you have access to a dyno rig you'd probably get slightly different results to what EVO got with their Mk5 Golf Gti and Fast Ford got with the Focus ST(?)

V-Power is the best high octane pump fuel and BP Ultimate is about the worst.

what car do you have? dont think i've seen you say and just wondered.

gingerman

tesco 99 because it right by my house and im lazy

rickbartlett

is bp ultimate that bad? its says on my torque of the devil paperwork to only use my car on bp ultimate?

Ed1

Its a peugeot 306 Xsi 2.0 16v, nothing amazing but you can tell the difference when you put decent petrol in it!

Lambchop

iTrader: (1)

Sweet, supposed to be a good engine

Personally i'd put normal petrol in anything non turbo as i'm a grip

rickbartlett

anyone tried the v power diesel????????

Mike1

Have a look at this test - everyone of these tests I've seen has used a different car and come up with slightly different results

Yeah it pulls so well, I got the Gti-6 gear box on it too and its made so much of a difference, Will shock quite a few cars off the lights, pulls like a train to 120 then i change into 6th and dont wanna go any faster, i get scared

I put V-power in it just coz im a gimp and like spending my money on my car!

Ed1

I was going to in my old van but i decided not to, Didnt wanna waste my money

rs2klee

im just using normal shell 95 atm.. not sure if it makes a difference as im just running in.. was told that to use normal fuel due to using mineral oil and to aid bedding in of the valves..95 in a redtop and 97+ in the greentops ? but did use optimax back then in the saph!

vroooom ptssssh

I'd only use Shell V power in a turbo motor!

Ed1

Do you get your shell card statements things throught the door every 1/4 or monthly, i havent got anything yet and i had it about 2 months!

Graceland

That burns so it ticks the box

sorry for the dumb question but is it actually bad to use 95 in a turbo? Is there much difference between 95 and 97 etc?

also would it matter much if you went from v power one day to bp ultimate a few days later and so on?

Depends on how close to the limits the car is set up. I always encourage people to bring their car in for mapping on the worst fuel they are likely to run, so if they can't always get V-Power and sometimes use BP Ultimate, I get them to have it mapped for Ultimate.

Forgetting scientific tests and so on, we absolutely positively see higher knock readings from BP Ultimate than we do from V-Power. I wouldn't put it in mine now at all and I used to swear by it.

i used to use Optimax all the while a few years ago in my last Track day S2. Now ive got the Primera trackcar, any old shit will do, cheaper the better! Current prefered tipple is Sainsburys finest 95ron!

I know of some people who ran the BP Ultimate diesel in fabia tdi VRS and they all said it smoked less than normal derv.

Remember guy,s these higher octaine fuels,loose the rating by a couple of point,if the petrol sits in your tank for a few weeks,so your 99ron becomes 97/96ish ron,and always use a busy petrol station,as the same thing happens in there tanks,if it sits to long

Over here, BP Ultimate and Mobil 8000 are ranked number 1 with Shell V Power and Caltex Vortex lower down. We used to get V Power Racing at some pumps which was 100 RON but that was phased out late last year sadly.

I work in the fuel industry here and it is quite interesting how the info is opposite to the UK as my cossie there lived on V Power.

What RON is Shell V-power down under?

In Uk its 99.

saff_cossie

98 here but we had V Power Racing which was 100 and at select service stations.

my stage 3 saff didnt like BP ultimate, in fact it felt less responsive and not as quick

i always used V power or at worst the tesco 99 Ron rated stuff

but nearly always it was V power

i wouldnt put anything less than 97 RON rated fuel in a cossie, but as said dont leave it sitting in your tank as it will lose potency.

rickbartlett

so whats better bp ultimate or tesco 99? just out of these 2?

Mike1

If you've got a CSL and have read the test above .......

....you'd have to plump for Tesco on the basis most people seem to rate V-Power higher
than BP Ultimate ( non 102 )

Might be different results in your car though.............

doctor stavros

Slightly off topic, but waht is best on a lesser tuned engine like my 1.8t in my Passat? I always use standard unleaded, whould i really reap any reward from going for tesco super as I always fill up at tesco

Mike1

Does it say anything on your filler cap/in your handbook about allowable values like up to 97/98 octane? If so your engine management might have adaptive knock control that can advance the ignition etc depending on info from knock sensors.
Stu MSD will know loads more than most on this but AFAIK the only way your car can tell what octane rating you've put in is by trying to feedback info from the knock sensors ( or other detonation sensors ) and depending on that altering the igniton system to advance it until it receives info telling it to stop/retard it from the knock sensors. Modern systems might be more intelligent perhaps but I'm sure that's how it used to work.
Your car will expect a minimum level of octane/whatever..............and then might have the ECU capacity to react positively to higher octane to take advantage.

Some older cars didn't have the capacity to do it automatically so you had to "set them up" to take advantage

It mentions 98 octane on my BMs filler cap and as I understand it the ECU will adapt up to that ( not sure if it would make full advantage of 102 though )

mobil 8000 for me.

POPEYE

I agree with Alan, i used to use optimax back in the UK but here Ultimate seems to get better results, plus the Ute is mapped on it aswell.
Never tried the 8000, might have to give it a go if i run low and not near a BP

Mike1

If anyone is interested I can scan the tests EVO mag did some while back using a V10 M5 and Mk5 Golf GTi.................ISTR it was a "Shell Special edition mag" though .....
