Filled the car with V-power the other day, £75 worth! Thumbs down

Anyway, everytime I start the car and pull away it hesitates for a couple of seconds, after that its fine. Only noticed it since I filled with V-power though. Seems worse when it's a cold start.

Any ideas?

I always run V-Power without exception, never had a problem...

As Chris says, try running on normal fuel again and see what happens. Smile

unlikely to be the fuel, but have you tried an ecu re-set?

I use V-Power in both my car and bike....and always have done. It seems to have a different smell when you put the fuel in than normal unleaded and even other brands of super.

I mainly use it for the cleaning detergents to be honest. Smile

i run super and ive got cold start hesitation like youve described but i dont think its the fuel. ive been running on it for 4 months and only recently had the problem.

personally id say neither of us have our problems caused by the fuel. have you considered other parts that can cause cold start hesitation?

The hesitation could be down to a lambda fault, or due to the fact it appears just after startup it could be the CTS has gone bad and is not supplying the engine with fuel enrichment.

I know what you mean about vpower smelling different stan, weird but it does seem different to normal fuel.

Yep, it certainly smells different, quite a nice smell too I think. LOL
At least with a different smell you definitely know you're putting V-Power in. Smile

Its a waste of time using the higher octane fuels. It makes no difference at all. Also the 97 is no cleaner than 95 so there are no benefits there.

The hesitation you may be experiencing will be due to the fact that 97 Resists ignition more than 95 fuel. Basically the higher the octane rating the more you engine will struggle to ignite the fuel.

I was once going to use V-Power but I too hesitated. I then just used normal Tesco 95 RON and saved a load of money.

Maybe it was your engine going "Really?"

Unless you're running boost, in which case fair play.

So for a super-charged 306 i should be using the 95 octane fuels as the premium stuff makes no difference?

If you say so Thumbs up

Have you used this tankful yet and tried standard unleaded again? Interested to know if the issue was resolved by changing the fuel back to normal 95...

The map for charged 6's is using high octane but if your car were to be mapped to 95, I'm sure that would be fine. In fact, it would be interesting to see if there is a power drop.

Standard cars are mapped to accept 95 or 97, although the handbook does advise to use 97. Yes

Obviously when a separate map is created then you should run with whatever fuel it was mapped on. Wink

So why is it better to run 97 octane fuel on a boosted 6's? Just wondering really

Lower octane fuels ignite more easily, so putting 95 in a car whose ECU is expecting fuel to not burn so easily can literally blow up your engine in seconds, as the fuel ignites before the piston reaches the top of the stroke.

Pre-ignition or knock, can't remember which one. Pre-ignition I think.

It's not that it's better, it's that it's absolutely essential if that's what your engine has been mapped for.

^^This

I would add that higher octane fuels can take more compression then lower octane fuels. It is therefore why you should use it in high compression engines, or engines that are low compression at build stage but when running boost create huge cylinder pressures requiring fuel that will take more pressure before self-ignitinng and causing detonation. Yes

Knock is when the fuel ignites before the spark has been introduced. Caused by having too low octane rating or high intake air temps.
