Hi people which is the better of the 2 fuels in you opinion
Tesco99 or vpower, I hear of most cars being mapped on vpower but with a Ron of 97 from vpower and tesco being Ron99 surely that would make the tesco a better choice,reason I'm asking is I'm getting my car mapped next week and need to fill the tank so looking for best option,

 

I thought V-power was 99?

 

V Power is 98

I mix and match tescos and shell ... on the whole I find shell a little more refined, and tescos has a bit more oomph .. but I could be just imagining it

 

It is

 

Hi there

I've used both,but as many mapper this will confirm V-power is more consistent than T99

On T99 we have better mileage,on V-power car feels more happy(or seems to be),checked both runs via Syvecs datalogging and there are small differences...

With meth think V-power is hard to beat.Car feels great and on the T99 don't know doesn't feels in this way

Many mappers still preferring V-power against T99,many people using T99 with the octane booster

We're still preferring the V-power if we could.

V power and tesco99 are both 99 so no difference really

 

Mine was mapped on V-Power and runs perfectly fine on T99

 

What's the difference in price anyone.
143.9 last night on the v-power.

 

Which booster do you use? I was watching a 5thgear and they tested 4 in a lab across different rev ranges and loads. Flushed the engine beetween tests, carried out at same engine temps etc etc, and according to the results they all lost power by -2% and one by -6%.
Wasnt a Subaru engine, think its on YouTube too

 

i found v power gave better cold start performance in my 93 wrx

 

Hi there

We are used only once NF Nitrous formula Race(black one) on the T99,no test on RR,just I've done datalogging on the Syvecs

Jura,

I know with Tesco99 they use additives to bring up the RON, but is there a problem using T99 with a 20% meth mix?

 

so vpower sounds like the fav in general but tesco99 will be perfectly fine to use aswell.
only reason i asked because i thought there might be a diffrent in performance, but ill stick with v power for now as thats what i have always run my car on

 

I was told that the most important thing is to stick to what the car was mapped on if possible, but most mappers seem to favour V Power. Mine only ever gets V Power with or without Meth, but Iv got a Shell garage at the end of my road so easy choice for me.

 

I've used tesco momentum in my 03 wrx ppp with no probe at all

 

+1 Better mpg and cheaper too (T99)

 

Mapped on Tesco runs fine on VP however the Tesco is normally a few pence cheaper.

 

Hi there

I don't think so you will have some problems using T99 with 20% meth,we are run without the problem T99 with 20% methanol or T99 with 65/35 water meth mix

Mine was mapped on Vpower, i have used T99 few times, performance wise no difference both are 99 Ron BUT i get better mpg on Vpower.
