Best petrol to use

[taff141177]

I ve heard v power is probably one of the best petrols to use the thing is I haven't got a shell garage nearby can any one recommend any other unleaded fuel to use instead of ordinary unleaded

 

[aaron-gardner]

What about a tesco? They sell 99 momentum at some stations. If not then I find personally that sainsburys super unleaded runs the best on my car next to these.

 

[taff141177]

Nice one yeah think Tesco has got the 99 momentum I've been using normal inleaded in mine for a year now and think its about time I started to use a better quality since a few others have said about using v power

 

[LukeK]

I don't see why there's a difference personally. Just a scam

 

[big eck]

I have to say my car runs better on the momentum 99 than the V Power.

Think I will fill up on 99 then got a bit of a trip down to South Wales tomorrow so I ll see what the mpg is like then

100% agree on this

100% agree on this

Nice one cheers for the info wish I had asked sooner now as I've been going past Tesco all the time

I have tried and tested all. Tesco Momentum is the best.!

I use momentum

And its not really a scam. My 1.4tsi requires at least 98ron as it has a supercharger! 95 ron retards the engine :O

Its not 'just' because its supercharged, many supercharged cars work fine on normal fuel. Its whether the map has been written to take advantage of super unleaded. My v5 is nowt special, but because it was designed to use super it has trouble with normal.

Put it in a car that can't use it and all you're doing is wasting money. So that is probably where the 'scam' thoughts come from.

My old mk2 tfsi specified 98 ron on the flap so nothing to do with being mapped

 

[putridmocha]

But mapped Cars definitely run better with good fuel
I use tesco personally

factory mapped for 98ron. many cars are mapped for 95 so won't take any advantage from better fuels

 

[putridmocha]

Most Cars Probably, just making the point that some unmapped Cars need 98

 

[LEE69]

Anything with a knock sensor will benefit

Yeah, so it was mapped by SEAT to run on 98. As Traumapat says, I'm not talking aftermarket 'remap', I'm talking standard factory map. All fuel injected cars have a map of some kind. Sorry if I confused the issue.

To get the most out of super unleaded, it needed to be burnt earlier in the cycle. If the map doesn't allow this, then it'll just get burnt at the same time as normal fuel and the extra energy will be wasted. Whether the car uses forced induction or is naturally aspirated, the fuel still needs to be burnt earlier than normal fuel would be.

Of course, if you burn normal fuel that early in the cycle it runs out of energy before it's able to push the piston down. This is pre-ignition, which is what a knock sensor is designed to cope with. If the knock sensor picks up pre-ignition, the ECU retards the spark so it can run on normal fuel, albeit with reduced output.

Plus you rack up the club card points lol

I've run mine for over 60,000 miles on v-Power / Tesco 99 ... I prefer v-Power simply down to the cleaning agents in the fuel which is good for the engine.

If you are re-mapped - Then you have to use Super
